Bisoprolol plus Hydrochlorothiazide is indicated in the treatment of Hypertension.

Combined antihypertensive preparations

Bisoprolol Fumarate and Hydrochlorothiazide have been used individually and in combination for the treatment of hypertension. The antihypertensive effects of these agents are additive; Hydrochlorothiazide 6.25 mg significantly increases the antihypertensive effect of Bisoprolol Fumarate. The incidence of hypokalemia with the Bisoprolol Fumarate and Hydrochlorothiazide 6.25 mg combination is significantly lower than with Hydrochlorothiazide 25 mg. Bisoprolol Fumarate is a β1-selective (cardioselective) adrenoceptor blocking agent without significant membrane stabilizing or intrinsic sympathomimetic activities in its therapeutic dose range. Hydrochlorothiazide is a benzothiadiazine diuretic. Thiazides affect renal tubular mechanisms of electrolyte reabsorption and increase excretion of sodium and chloride in approximately equivalent amounts

Bisoprolol is an effective treatment of hypertension in once-daily doses of 2.5 to 40 mg, while Hydrochlorothiazide is effective in doses of 12.5 to 50 mg. In clinical trials of Bisoprolol/Hydrochlorothiazide combination therapy using Bisoprolol doses of 2.5 to 20 mg and Hydrochlorothiazide doses of 6.25 to 25 mg, the antihypertensive effects increased with increasing doses of either component.

Initial Therapy: Antihypertensive therapy may be initiated with the lowest dose of this conbination, one 2.5/6.25 mg tablet once daily. Subsequent titration (14 day intervals) may be carried out with this tablets up to the maximum recommended dose 20/12.5 mg once daily, as appropriate.

Replacement Therapy: The combination may be substituted for the titrated individual components.

Therapy Guided by Clinical Effect: A patient whose blood pressure is not adequately controlled with 2.5-20 mg Bisoprolol daily may instead be given this conbination. Patients whose blood pressures are adequately controlled with 50 mg of hydrochlorothiazide daily, but who experience significant potassium loss with this regimen, may achieve similar blood pressure control without electrolyte disturbance if they are switched to this conbination.

Generally well tolerated. Most side effects have been mild and transient. Side effects which may occur: fatigue, dizziness, headache, bradycardia, arrhythmia, peripheral ischemia, chest pain, palpitations, rhythm disturbances, cold extremities, claudication, orthostatic hypotension, diarrhoea, constipation, nausea, dyspepsia, rhinitis, pharyngitis etc.

It is contraindicated in patients in cardiogenic shock, overt cardiac failure, second or third degree AV block, marked sinus bradycardia, anuria and hypersensitivity to either component of this product or to other sulfonamide-derived drugs.

Hyperuricemia or acute gout may be precipitated in certain patients receiving thiazide diuretics. Warning signs or symptoms of fluid and electrolyte imbalance include dryness of mouth, thirst, weakness, lethargy, drowsiness, restlessness, muscle pains or cramps, muscular fatigue, hypotension, oliguria, tachycardia and gastrointestinal disturbances such as nausea and vomiting. Hypokalemia may develop. If withdrawal of this combination therapy is planned, it should be achieved gradually over a period of about 2 weeks. Patients should be carefully observed.

This combination drug may potentiate the action of other antihypertensive agents used concomitantly. This combination drug should not be combined with other beta-blocking agents. Patients receiving catecholamine-depleting drugs, such as reserpine or guanethidine, should be closely monitored because the added beta-adrenergic blocking action of Bisoprolol Fumarate may produce excessive reduction of sympathetic activity. In patients receiving concurrent therapy with clonidine, if therapy is to be discontinued, it is suggested that this combination drug be discontinued for several days before the withdrawal of clonidine. This combination drug should be used with caution when myocardial depressants or inhibitors of AV conduction, such as certain calcium antagonists (particularly of the phenylalkylamine [verapamil] and benzothiazepine [diltiazem] classes) or antiarrhythmic agents, such as disopyramide, are used concurrently. Both digitalis glycosides and beta-blockers slow atrioventricular conduction and decrease heart rate. Concomitant use can increase the risk of bradycardia.

Use in Pregnancy: Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Bisoprolol Fumarate and Hydrochlorothiazide should be used during pregnancy only if the potential benefit justifies the risk to the fetus.

Use in Nursing Mothers: Bisoprolol Fumarate alone or in combination with Hydrochlorothiazide has not been studied in nursing mothers. Thiazides are excreted in human breast milk. Small amounts of Bisoprolol Fumarate have been detected in the milk of lactating rats. Because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

There are limited data on overdose with this combination product. The most frequently observed signs expected with overdosage of a beta-blocker are bradycardia and hypotension. Lethargy is also common and with severe overdoses, delirium, coma, convulsions, and respiratory arrest have been reported to occur. Congestive heart failure, bronchospasm, and hypoglycemia may occur. With thiazide diuretics, acute intoxication is rare. The most prominent feature of overdose is acute loss of fluid and electrolytes. Signs and symptoms include cardiovascular (tachycardia, hypotension, shock), neuromuscular (weakness, confusion, dizziness, cramps of the calf muscles, paresthesia, fatigue, impairment of consciousness), gastrointestinal (nausea, vomiting, thirst), renal (polyuria, oliguria, or anuria), and laboratory findings (hypokalemia, hyponatremia, hypochloremia, alkalosis, increased BUN [especially in patients with renal insufficiency]).

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

Combined antihypertensive preparations

This is a fixed-dose combination of Amlodipine and Atenolol. Amlodipine is a dihydropyridine calcium antagonist that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle; it has a greater effect on vascular smooth muscle than on cardiac muscle. Amlodipine is a peripheral vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and reduction in blood pressure. Amlodipine reduces tone, decreases coronary vasoreactivity and lowers cardiac demand by reducing afterload.

Atenolol is a cardioselective beta-blocker. The cardio-selectivity is dose-related. Atenolol causes a reduction in blood pressure by lowering cardiac output, decreasing the plasma renin activity and sympathetic outflow from CNS. Atenolol also causes a reduction in myocardial oxygen demand by virtue of its negative inotropic and negative chronotropic effects.

The recommended dosage is Amlodipine and Atenolol 5/25 mg tablet once daily. If necessary, the dosage may be increased to 5/25 mg two tablets daily or as advised by the physicians. The dosage however should be individualized.

The combination of Amlodipine and Atenolol is well tolerated. Overall side-effects include
fatigue, headache, edema, nausea, drowsiness, anxiety and depression.

Hypersensitivity to either component, sinus bradycardia, second and higher degrees of heart block, cardiogenic shock, hypotension, congestive heart failure, poor left ventricular function.

Bronchospasm: The combination should be used with caution in patients with airway obstruction.

Renal impairment: The combination can be used in patients with renal impairment. However, caution may be necessary if the creatinine clearance is less than 30 ml/min because of possible reduction in the excretion of unchanged Atenolol.

Hepatic impairment: Caution may be necessary in the use of the combination in patients with severe liver damage because of prolongation of the elimination half-life of Amlodipine.

Drug withdrawal: Since coronary heart disease may exist without being recognized, patients should be warned against stopping the drug suddenly. Any discontinuation should be gradual and under observation.

Disopyramide: Atenolol reduces the clearance of disopyramide by 20%. Additive negative inotropic effects on the heart may be produced.

Ampicillin: at doses of 1 gm and above may reduce Atenolol levels.

Oral antidiabetics and insulin: Beta-blockers may decrease tissue sensitivity to insulin and inhibit insulin secretion e.g. in response to oral antidiabetics. Atenolol has less potential for these actions.

The combination should be used during pregnancy only if the expected benefit outweighs the potential fetal risk. The combination should not be used by nursing mothers. If its use is considered necessary, breast-feeding should be stopped.

Though not documented, hypotension and less frequently congestive cardiac failure may occur in cases of overdosage. Unabsorbed drugs may be removed by gastric lavage or administration of activated charcoal. Symptomatic treatment is suggested.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

This is indicated in-

• Patients with essential hypertension
• Patients with angina pectoris & hypertension as co-existing diseases
• ln post Ml patients
• ln patients with refractory angina pectoris where nitrate therapy has failed.

Atenolol is indicated-

• In the management of hypertension. It may be used alone or concomitantly with other antihypertensive agents, particularly with a thiazide-type diuretic.
• For the long-term management of patients with angina pectoris.
• In the management of hemodynamically stable patients with defnite or suspected acute myocardial infarction to reduce cardiovascular mortality.

Beta-adrenoceptor blocking drugs, Beta-blockers

The synthesis of atenolol resulted from attempts to produce a β-adrenoceptor antagonist that would competitively block β1 (cardiac) receptors but have no effect on β2-receptors. It is classified as a β1 selective (cardioselective) β-adrenergic receptor antagonist with no membranestability activity and no partial agonist activity. It is markedly the most hydrophilic of the currently available β- blockers and thus penetrates the lipid of cell membranes poorly

Hypertension: The initial dose of Atenolol is 50 mg given as one tablet a day either alone or added to diuretic therapy. The full effect of this dose will usually be seen within one to two weeks. If an optimal response is not achieved, the dosage should be increased to Atenolol 100 mg given as one tablet a day. Increasing the dosage beyond 100 mg a day is unlikely to produce any further benefit.

Angina Pectoris: The initial dose of Atenolol is 50 mg given as one tablet a day. If an optimal response is not achieved within one week, the dosage should be increased to Atenolol 100 mg given as one tablet a day. Some patients may require a dosage of 200 mg once a day for optimal effect. Twenty-four hour control with once daily dosing is achieved by giving doses larger than necessary to achieve an immediate maximum effect. The maximum early effect on exercise tolerance occurs with doses of 50 to 100 mg, but at these doses the effect at 24 hours is attenuated, averaging about 50% to 75% of that observed with once a day oral doses of 200 mg.

Acute Myocardial Infarction: In patients with definite or suspected acute myocardial infarction, treatment with Atenolol I.V. Injection should be initiated as soon as possible after the patient's arrival in the hospital and after eligibility is established. Treatment should begin with the intravenous administration of 5 mg Atenolol over 5 minutes followed by another 5 mg intravenous injection 10 minutes later. In patients who tolerate the full intravenous dose (10 mg), Atenolol Tablets 50 mg should be initiated 10 minutes after the last intravenous dose followed by another 50 mg oral dose 12 hours later. Thereafter, Atenolol can be given orally either 100 mg once daily or 50 mg twice a day for a further 6-9 days or until discharge from the hospital. If bradycardia or hypotension requiring treatment or any other untoward effects occur, Atenolol should be discontinued.

In a series of investigations in the treatment of acute myocardial infarction, bradycardia and hypotension occurred more commonly, as expected for any beta blocker. In addition, a variety of adverse efects has been reported with other beta-adrenergic blocking agents, and may be considered potential adverse efects of Atenolol.

• Hematologic: Agranulocytosis.
• Allergic: Fever, combined with aching and sore throat, laryngospasm, and respiratory distress.
• Central Nervous System: Reversible mental depression progressing to catatonia; an acute reversible syndrome characterized by disorientation of time and place; short term memory loss; emotional lability with slightly clouded sensorium; and, decreased performance on neuropsychometrics.
• Gastrointestinal: Mesenteric arterial thrombosis, ischemic colitis.
• Miscellaneous: There have been reports of skin rashes and/or dry eyes associated with the use of beta-adrenergic blocking drugs. Discontinuance of the drug should be considered if any such reaction is not otherwise explicable. Patients should be closely monitored following cessation of therapy.
• Other: Erythematous rash

Atenolol is contraindicated in-

• Sinus bradycardia, heart block greater than first degree, cardiogenic shock, and overt cardiac failure.
• Those patients with a history of hypersensitivity to the atenolol or any of the drug product’s components.

General: Patients already on a beta blocker must be evaluated carefully before Atenolol is administered. Initial and subsequent Atenolol dosages can be adjusted downward depending on clinical observations including pulse and blood pressure. Atenolol may aggravate peripheral arterial circulatory disorders.

Impaired Renal Function: The drug should be used with caution in patients with impaired renal function.

Geriatric Use:

• Hypertension and Angina Pectoris: Due to Coronary Atherosclerosis: Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
• Acute Myocardial Infarction: Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Evaluation of patients with hypertension or myocardial infarction should always include assessment of renal function.

Pregnancy Category D. Caution should be exercised when Atenolol is administered to a nursing woman. Clinically significant bradycardia has been reported in breast-fed infants. Premature infants, or infants with impaired renal function, may be more likely to develop adverse effects.

Elderly Patients or Patients with Renal Impairment: Atenolol is excreted by the kidneys; consequently dosage should be adjusted in cases of severe impairment of renal function. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, refecting greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. The following maximum oral dosages are recommended for elderly, renal impaired patients and for patients with renal impairment due to other causes:

• Creatinine clearance 15-35 ml/min/1.73 m²: Maximum dosage 50 mg daily
• Creatinine clearance <15 mL/min/1.73 m²: Maximum dosage 25 mg daily

Some renal impaired or elderly patients being treated for hypertension may require a lower starting dose of Atenolol: 25 mg given as one tablet a day. Patients on hemodialysis should be given 25 mg or 50 mg after each dialysis; this should be done under hospital supervision as marked falls in blood pressure can occur.

Overdosage with Atenolol has been reported with patients surviving acute doses as high as 5 g. One death was reported in a man who may have taken as much as 10 g acutely. The predominant symptoms reported following Atenolol overdose are lethargy, disorder of respiratory drive, wheezing, sinus pause and bradycardia. Additionally, common efects associated with overdosage of any beta-adrenergic blocking agent and which might also be expected in Atenolol overdose are congestive heart failure, hypotension, bronchospasm and/or hypoglycemia. Treatment of overdose should be directed to the removal of any unabsorbed drug by induced emesis, gastric lavage, or administration of activated charcoal. Atenolol can be removed from the general circulation by hemodialysis. Based on the severity of symptoms, management may require intensive support care and facilities for applying cardiac and respiratory support.

Do not use later than the date of expiry. Keep all medicines out of the reach of children. To be dispensed only on the prescription of a registered physician.

This combination is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure lowers the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions.

Combined antihypertensive preparations

Atenolol and chlorthalidone have been used singly and concomitantly for the treatment of hypertension. Studies have shown that there is no interference with bioavailability when these agents are given together in the single combination tablet. Therefore, this combination provides a convenient formulation for the concomitant administration of these two drugs.

Atenolol is a beta1-selective (cardioselective) beta-adrenergic receptor blocking agent that provides-

• reduction in resting and exercise heart rates and cardiac output
• reduction of systolic and diastolic blood pressure at rest and on exercise
• reduction in reflex orthostatic tachycardia.

Chlorthalidone is a monosulfonamyl diuretic with prolonged action and low toxicity. It produces diuresis with greatly increased excretion of sodium and chloride at distal convoluted tubule of the nephron.

The initial dose is Atenolol 50 mg and Chlorthalidone 25 mg once a day. If an optimal response is not achieved, another antihypertensive agent may be added gradually beginning with 50 percent of the usual recommended starting dose to avoid an excessive fall in blood pressure. Atenolol is excreted via kidneys and therefore dosage should be adjusted in cases of severe impairment of renal function.

Use in elderly: Clinical studies of Atenolol & Chlorthalidone combination did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

The adverse effects observed for this combination are essentially the same as those seen with the individual components. Atenolol: Bradycardia, Cold Extremities, Postural Hypotension, Leg Pain, Dizziness, Vertigo, Light Headedness, Tiredness, Fatigue, Lethargy, Drowsiness, Depression, Dreaming, Diarrhea, Nausea, Wheeziness, Dyspnea, Chlorthalidone Orthostatic hypotension, anorexia, gastric irritation, vomiting, cramping, constipation, vertigo, purpura, photosensitivity, rash, urticaria, hyperglycemia, glycosuria, hyperuricemia, muscle spasm, weakness, restlessness.

Atenolol and Chlorthalidone combination is contraindicated in hypersensitivity to this product or to sulfonamide-derived drugs. It is also contraindicated in patients with sinus bradycardia, heart block greater than first degree, cardiogenic shock, overt cardiac failure and anuria.

This combination may aggravate peripheral arterial circulatory disorders. Periodic determination of serum electrolytes to detect possible electrolyte imbalance should be performed at appropriate intervals.

Pregnancy Category D. Caution should be exercised when this drug is administered to a woman who is breastfeeding.

No specific information is available with regard to overdosage of this combination in humans. Treatment should be symptomatic and supportive and directed to the removal of any unabsorbed drug by induced emesis, or administration of activated charcoal. Atenolol can be removed from the general circulation by hemodialysis. Further consideration should be given to dehydration, electrolyte imbalance and hypotension by established procedures.

Store in cool and dry place, protected from light.

This is indicated in-

• Patients with essential hypertension
• Patients with angina pectoris & hypertension as co-existing diseases
• ln post Ml patients
• ln patients with refractory angina pectoris where nitrate therapy has failed.

The combination of Amlodipine and Atenolol is well tolerated. Overall side-effects include
fatigue, headache, edema, nausea, drowsiness, anxiety and depression.

Hypersensitivity to either component, sinus bradycardia, second and higher degrees of heart block, cardiogenic shock, hypotension, congestive heart failure, poor left ventricular function.

Bronchospasm: The combination should be used with caution in patients with airway obstruction.

Renal impairment: The combination can be used in patients with renal impairment. However, caution may be necessary if the creatinine clearance is less than 30 ml/min because of possible reduction in the excretion of unchanged Atenolol.

Hepatic impairment: Caution may be necessary in the use of the combination in patients with severe liver damage because of prolongation of the elimination half-life of Amlodipine.

Drug withdrawal: Since coronary heart disease may exist without being recognized, patients should be warned against stopping the drug suddenly. Any discontinuation should be gradual and under observation.

Disopyramide: Atenolol reduces the clearance of disopyramide by 20%. Additive negative inotropic effects on the heart may be produced.

Ampicillin: at doses of 1 gm and above may reduce Atenolol levels.

Oral antidiabetics and insulin: Beta-blockers may decrease tissue sensitivity to insulin and inhibit insulin secretion e.g. in response to oral antidiabetics. Atenolol has less potential for these actions.

The combination should be used during pregnancy only if the expected benefit outweighs the potential fetal risk. The combination should not be used by nursing mothers. If its use is considered necessary, breast-feeding should be stopped.

Though not documented, hypotension and less frequently congestive cardiac failure may occur in cases of overdosage. Unabsorbed drugs may be removed by gastric lavage or administration of activated charcoal. Symptomatic treatment is suggested.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

This is indicated in-

• Patients with essential hypertension
• Patients with angina pectoris & hypertension as co-existing diseases
• ln post Ml patients
• ln patients with refractory angina pectoris where nitrate therapy has failed.

Combined antihypertensive preparations

This is a fixed-dose combination of Amlodipine and Atenolol. Amlodipine is a dihydropyridine calcium antagonist that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle; it has a greater effect on vascular smooth muscle than on cardiac muscle. Amlodipine is a peripheral vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and reduction in blood pressure. Amlodipine reduces tone, decreases coronary vasoreactivity and lowers cardiac demand by reducing afterload.

Atenolol is a cardioselective beta-blocker. The cardio-selectivity is dose-related. Atenolol causes a reduction in blood pressure by lowering cardiac output, decreasing the plasma renin activity and sympathetic outflow from CNS. Atenolol also causes a reduction in myocardial oxygen demand by virtue of its negative inotropic and negative chronotropic effects.

The recommended dosage is Amlodipine and Atenolol 5/25 mg tablet once daily. If necessary, the dosage may be increased to 5/25 mg two tablets daily or as advised by the physicians. The dosage however should be individualized.

The combination of Amlodipine and Atenolol is well tolerated. Overall side-effects include

Tenoxicam is indicated for the symptomatic treatment of the following painful inflammatory and degenerative disorders of the musculoskeletal system:

• Rheumatoid arthritis.
• Osteoarthritis.
• Arthrosis.
• Ankylosing spondylitis.
• Extra-articular disorders, e.g. tendinitis, bursitis, periarthritis of the shoulders (shoulder-hand syndrome) or hips, strains, and sprains.
• Acute gout.

Drugs for Osteoarthritis, Drugs used for Rheumatoid Arthritis, Non-steroidal Anti-inflammatory Drugs (NSAIDs)

Tenoxicam is a non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic and antipyretic properties and it also inhibits platelet aggregation. Tenoxicam inhibits prostaglandin biosynthesis. In-vitro tests of leukocyte peroxidase suggest that tenoxicam may act as a scavenger for active oxygen at the site of inflammation. Tenoxicam is a potent in-vitro inhibitor of human metalloproteinases (stromelysin and collagenase), which induce cartilage breakdown. These pharmacological effects explain, at least in part, the therapeutic benefit of Tenoxicam in the treatment of painful inflammatory and degenerative disorders of the musculoskeletal system. Tenoxicam showed no mutagenic, carcinogenic or teratogenic effects in animals. As with other prostaglandin inhibitors, renal and gastrointestinal effects, increased incidence of dystocia and delayed parturition were observed in animal safety studies.

Standard dosage: For all indications except acute gout, a daily dosage of 20 mg should be given at the same time of day.

In acute attacks of gout: The recommended dose for acute attacks of gout is 40 mg once daily for two days followed by 20 mg once daily for a further five days.

In the treatment of chronic disorders: The therapeutic effect of tenoxicam is evident early in treatment but there is a progressive increase in response over time. In chronic disorders, daily doses higher than 20 mg should be avoided since this would increase the frequency and intensity of unwanted reactions without significantly increasing efficacy. For patients needing long-term treatment, a reduction to a daily oral dose of 10 mg may be tried for maintenance.

Special dosage instructions: In principle, the above dosage recommendations also apply to elderly patients and to patients suffering from kidney or liver disease. Because of lack of clinical experience, no dosage recommendations have so far been established for children and adolescents.

The tablets should be taken with a glass of water. It is preferable to take this medicine during or immediately after a meal.

Based on clinical trials including large numbers of patients, Tenoxicam proved to be well tolerated in the recommended dose. Usually, the undesirable effects reported were mild and transient. In a small proportion of patients, the interruption of treatment due to undesirable effects was necessary. Local tolerance of Tenoxicam given parenterally was good. The following undesirable effects have been reported:

Frequency is greater than 1%-

• Gastrointestinal tract: gastric, epigastric and abdominal discomfort, dyspepsia, heartburn, nausea.
• Central nervous system: dizziness, headache.

Frequency less than 1%-

• Gastrointestinal tract: constipation, diarrhea, stomatitis, gastritis, vomiting, ulcers, Gl-bleeding including hematemesis and melena.
• Central nervous system: fatigue, sleep disturbances, appetite loss, dry mouth, vertigo.
• Skin: itching (also in the anal region after rectal administration), erythema, exanthema, rash, urticaria.
• Urinary tract and kidneys: increase in BUN or creatinine, edema.
• Liver and biliary tract: increased liver enzyme activity.
• Cardiovascular system: palpitations.

Isolated cases (frequency less than 0.01%)-

• Gastrointestinal tract: Gl-perforation.
• Central nervous system: visual disturbances.
• Skin: Stevens-Johnson and Lyell's syndrome, photosensitivity reaction, vasculitis.
• Blood: anemia, agranulocytosis, leukopenia, thrombocytopenia.
• Hypersensitivity reactions: dyspnea, asthma, anaphylaxis, angioedema.
• Cardiovascular system: elevated blood pressure, mainly in patients treated with cardiovascular drugs.
• Liver/Biliary tract: hepatitis.

Tenoxicam must not be administered to patients:

• known to be hypersensitive to the drug;
• in whom salicylates or other non-steroidal anti-inflammatory drugs (NSAIDs) induce symptoms of asthma, rhinitis, or urticaria;
• suffering or having suffered from the disease of the upper gastrointestinal tract, such as gastritis, gastric and duodenal ulcer.

NSAIDs inhibit renal prostaglandin synthesis and consequently may have an undesirable effect on renal hemodynamics and on salt and water balance. It is necessary to adequately monitor the patient with a special emphasis on cardiac and renal function (BUN, creatinine, development of edema, weight gain, etc.) when giving Tenoxicam to patients with conditions that could increase their risk of developing renal failure, such as pre-existing renal disease, impaired renal function in diabetics, hepatic cirrhosis, congestive heart failure, volume depletion or concomitant treatment with potentially nephrotoxic drugs, diuretics and corticosteroids. Tenoxicam inhibits platelet aggregation and may affect hemostasis. Tenoxicam has no significant influence on blood coagulation factors, coagulation time, prothrombin time or activated thromboplastin time. Patients having coagulation disorders or receiving drug therapy that interferes with hemostasis should, however, be carefully observed when Tenoxicam is administered. Any patient being treated with Tenoxicam who presents with symptoms of gastrointestinal disease should be closely monitored. If peptic ulceration or gastrointestinal bleeding occurs, Tenoxicam should be immediately withdrawn. If severe skin reactions (e.g. Lyell's or Stevens-Johnson syndrome) occur, the treatment should be discontinued immediately. Adverse eye findings have been reported with Tenoxicam. Thus ophthalmic evaluation is recommended for patients who develop visual disturbances. Because of the high plasma protein binding of tenoxicam, caution is required when plasma albumin levels are markedly reduced. In common with anti-inflammatory drugs, Tenoxicam may mask the usual signs of infection. Tenoxicam Tablets should not be given to patients who either dislike or do not tolerate milk products.

As in the case of other NSAIDs, salicylate displaces tenoxicam from protein-binding sites and increases clearance and volume of distribution of tenoxicam. Concurrent treatment with salicylate or other NSAIDs should be avoided because of increased risk of gastrointestinal undesirable reactions. The co-administration of some NSAIDs and methotrexate has been associated with reduced renal tubular secretion of methotrexate, higher plasma concentrations of methotrexate, and severe methotrexate toxicity. Therefore, caution should be exercised when Tenoxicam is administered concurrently with methotrexate. No clinically relevant interaction was found in the small number of patients receiving concomitant treatment with gold, penicillamine or probenecid. As Tenoxicam may decrease the renal clearance of lithium, their concomitant administration may lead to increased plasma levels and toxicity of lithium. The plasma levels of lithium should be closely monitored. As with NSAIDs in general, Tenoxicam should not be administered concurrently with K-sparing diuretics. There is a known interaction between these two classes of compounds, which may cause hyperkalemia and renal failure. No clinically significant interaction between Tenoxicam and furosemide was noted, but Tenoxicam attenuates the blood pressure-lowering effect of hydrochlorothiazide. As known from other NSAIDs, Tenoxicam might attenuate the antihypertensive effects of alpha-adrenergic blockers and ACE-inhibitors. No interactions have been reported between NSAIDs and centrally-acting alpha agonists or calcium channel blockers. There was no clinically relevant interaction when Tenoxicam was administered together with atenolol. During clinical trials no interaction was reported for patients treated concomitantly with digitalis products. Thus concurrent dosing of Tenoxicam and digoxin appears to be without major risk. No interaction has been found with concomitantly administered antacids, cimetidine, warfarin and phenprocoumon at the recommended dosages. The clinical effect of oral antidiabetic drugs (glibornuride, glibenclamide, tolbutamide) was likewise not modified by Tenoxicam. Nevertheless, careful monitoring is recommended when patients concomitantly receive anticoagulants or oral antidiabetic drugs. No clinically relevant interaction has been found between Tenoxicam and low molecular weight heparin.

NSAIDs have an inhibitory effect on prostaglandin synthesis and, when given during late pregnancy, may cause the closure of the fetal ductus arteriosus, prolong labor and delay parturition. Treatment during the third trimester of pregnancy should be avoided. Based on findings from single-dose administration, a very small amount (approximately 0.2%) of tenoxicam passes into breast milk. There is no evidence of adverse reactions in breast-fed infants of mothers taking Tenoxicam. Nevertheless, infants should be weaned or the drug discontinued.

Use in Children & adolescent: Tenoxicam is not recommended for use in patients under 16 years of age, as the dose and indications in this population have not been established.

Effects on ability to drive and use machines: Patients experiencing adverse events that might affect driving or using machines, such as vertigo, dizziness or visual disturbances should refrain from driving a car or using machines.

Although there is no experience of acute overdosage with Tenoxicam, it may be expected that the signs and symptoms mentioned under Undesirable effects would be more pronounced. Overdose should be countered by conventional measures to reduce absorption (e.g. gastrolavage and charcoal) and speed up elimination (e.g. cholestyramine).

Do not store above 30°C, protect from light & moisture. Keep out of the reach of children.

Atenolol is indicated-

• In the management of hypertension. It may be used alone or concomitantly with other antihypertensive agents, particularly with a thiazide-type diuretic.
• For the long-term management of patients with angina pectoris.
• In the management of hemodynamically stable patients with defnite or suspected acute myocardial infarction to reduce cardiovascular mortality.

Beta-adrenoceptor blocking drugs, Beta-blockers

The synthesis of atenolol resulted from attempts to produce a β-adrenoceptor antagonist that would competitively block β1 (cardiac) receptors but have no effect on β2-receptors. It is classified as a β1 selective (cardioselective) β-adrenergic receptor antagonist with no membranestability activity and no partial agonist activity. It is markedly the most hydrophilic of the currently available β- blockers and thus penetrates the lipid of cell membranes poorly

Hypertension: The initial dose of Atenolol is 50 mg given as one tablet a day either alone or added to diuretic therapy. The full effect of this dose will usually be seen within one to two weeks. If an optimal response is not achieved, the dosage should be increased to Atenolol 100 mg given as one tablet a day. Increasing the dosage beyond 100 mg a day is unlikely to produce any further benefit.

Angina Pectoris: The initial dose of Atenolol is 50 mg given as one tablet a day. If an optimal response is not achieved within one week, the dosage should be increased to Atenolol 100 mg given as one tablet a day. Some patients may require a dosage of 200 mg once a day for optimal effect. Twenty-four hour control with once daily dosing is achieved by giving doses larger than necessary to achieve an immediate maximum effect. The maximum early effect on exercise tolerance occurs with doses of 50 to 100 mg, but at these doses the effect at 24 hours is attenuated, averaging about 50% to 75% of that observed with once a day oral doses of 200 mg.

Acute Myocardial Infarction: In patients with definite or suspected acute myocardial infarction, treatment with Atenolol I.V. Injection should be initiated as soon as possible after the patient's arrival in the hospital and after eligibility is established. Treatment should begin with the intravenous administration of 5 mg Atenolol over 5 minutes followed by another 5 mg intravenous injection 10 minutes later. In patients who tolerate the full intravenous dose (10 mg), Atenolol Tablets 50 mg should be initiated 10 minutes after the last intravenous dose followed by another 50 mg oral dose 12 hours later. Thereafter, Atenolol can be given orally either 100 mg once daily or 50 mg twice a day for a further 6-9 days or until discharge from the hospital. If bradycardia or hypotension requiring treatment or any other untoward effects occur, Atenolol should be discontinued.

In a series of investigations in the treatment of acute myocardial infarction, bradycardia and hypotension occurred more commonly, as expected for any beta blocker. In addition, a variety of adverse efects has been reported with other beta-adrenergic blocking agents, and may be considered potential adverse efects of Atenolol.

• Hematologic: Agranulocytosis.
• Allergic: Fever, combined with aching and sore throat, laryngospasm, and respiratory distress.
• Central Nervous System: Reversible mental depression progressing to catatonia; an acute reversible syndrome characterized by disorientation of time and place; short term memory loss; emotional lability with slightly clouded sensorium; and, decreased performance on neuropsychometrics.
• Gastrointestinal: Mesenteric arterial thrombosis, ischemic colitis.
• Miscellaneous: There have been reports of skin rashes and/or dry eyes associated with the use of beta-adrenergic blocking drugs. Discontinuance of the drug should be considered if any such reaction is not otherwise explicable. Patients should be closely monitored following cessation of therapy.
• Other: Erythematous rash

Atenolol is contraindicated in-

• Sinus bradycardia, heart block greater than first degree, cardiogenic shock, and overt cardiac failure.
• Those patients with a history of hypersensitivity to the atenolol or any of the drug product’s components.

General: Patients already on a beta blocker must be evaluated carefully before Atenolol is administered. Initial and subsequent Atenolol dosages can be adjusted downward depending on clinical observations including pulse and blood pressure. Atenolol may aggravate peripheral arterial circulatory disorders.

Impaired Renal Function: The drug should be used with caution in patients with impaired renal function.

Geriatric Use:

• Hypertension and Angina Pectoris: Due to Coronary Atherosclerosis: Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
• Acute Myocardial Infarction: Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Evaluation of patients with hypertension or myocardial infarction should always include assessment of renal function.

Pregnancy Category D. Caution should be exercised when Atenolol is administered to a nursing woman. Clinically significant bradycardia has been reported in breast-fed infants. Premature infants, or infants with impaired renal function, may be more likely to develop adverse effects.

Elderly Patients or Patients with Renal Impairment: Atenolol is excreted by the kidneys; consequently dosage should be adjusted in cases of severe impairment of renal function. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, refecting greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. The following maximum oral dosages are recommended for elderly, renal impaired patients and for patients with renal impairment due to other causes:

• Creatinine clearance 15-35 ml/min/1.73 m²: Maximum dosage 50 mg daily
• Creatinine clearance <15 mL/min/1.73 m²: Maximum dosage 25 mg daily

Some renal impaired or elderly patients being treated for hypertension may require a lower starting dose of Atenolol: 25 mg given as one tablet a day. Patients on hemodialysis should be given 25 mg or 50 mg after each dialysis; this should be done under hospital supervision as marked falls in blood pressure can occur.

Overdosage with Atenolol has been reported with patients surviving acute doses as high as 5 g. One death was reported in a man who may have taken as much as 10 g acutely. The predominant symptoms reported following Atenolol overdose are lethargy, disorder of respiratory drive, wheezing, sinus pause and bradycardia. Additionally, common efects associated with overdosage of any beta-adrenergic blocking agent and which might also be expected in Atenolol overdose are congestive heart failure, hypotension, bronchospasm and/or hypoglycemia. Treatment of overdose should be directed to the removal of any unabsorbed drug by induced emesis, gastric lavage, or administration of activated charcoal. Atenolol can be removed from the general circulation by hemodialysis. Based on the severity of symptoms, management may require intensive support care and facilities for applying cardiac and respiratory support.

Do not use later than the date of expiry. Keep all medicines out of the reach of children. To be dispensed only on the prescription of a registered physician.

• Creatinine clearance <15 mL/min/1.73 m²: Maximum dosage 25 mg daily

Some renal impaired or elderly patients being treated for hypertension may require a lower starting dose of Atenolol: 25 mg given as one tablet a day. Patients on hemodialysis should be given 25 mg or 50 mg after each dialysis; this should be done under hospital supervision as marked falls in blood pressure can occur.

Overdosage with Atenolol has been reported with patients surviving acute doses as high as 5 g. One death was reported in a man who may have taken as much as 10 g acutely. The predominant symptoms reported following Atenolol overdose are lethargy, disorder of respiratory drive, wheezing, sinus pause and bradycardia. Additionally, common efects associated with overdosage of any beta-adrenergic blocking agent and which might also be expected in Atenolol overdose are congestive heart failure, hypotension, bronchospasm and/or hypoglycemia. Treatment of overdose should be directed to the removal of any unabsorbed drug by induced emesis, gastric lavage, or administration of activated charcoal. Atenolol can be removed from the general circulation by hemodialysis. Based on the severity of symptoms, management may require intensive support care and facilities for applying cardiac and respiratory support.

Do not use later than the date of expiry. Keep all medicines out of the reach of children. To be dispensed only on the prescription of a registered physician.

Tenoxicam is indicated for the symptomatic treatment of the following painful inflammatory and degenerative disorders of the musculoskeletal system:

• Rheumatoid arthritis.
• Osteoarthritis.
• Arthrosis.
• Ankylosing spondylitis.
• Extra-articular disorders, e.g. tendinitis, bursitis, periarthritis of the shoulders (shoulder-hand syndrome) or hips, strains, and sprains.
• Acute gout.

Drugs for Osteoarthritis, Drugs used for Rheumatoid Arthritis, Non-steroidal Anti-inflammatory Drugs (NSAIDs)

Tenoxicam is a non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic and antipyretic properties and it also inhibits platelet aggregation. Tenoxicam inhibits prostaglandin biosynthesis. In-vitro tests of leukocyte peroxidase suggest that tenoxicam may act as a scavenger for active oxygen at the site of inflammation. Tenoxicam is a potent in-vitro inhibitor of human metalloproteinases (stromelysin and collagenase), which induce cartilage breakdown. These pharmacological effects explain, at least in part, the therapeutic benefit of Tenoxicam in the treatment of painful inflammatory and degenerative disorders of the musculoskeletal system. Tenoxicam showed no mutagenic, carcinogenic or teratogenic effects in animals. As with other prostaglandin inhibitors, renal and gastrointestinal effects, increased incidence of dystocia and delayed parturition were observed in animal safety studies.

Standard dosage: For all indications except acute gout, a daily dosage of 20 mg should be given at the same time of day.

In acute attacks of gout: The recommended dose for acute attacks of gout is 40 mg once daily for two days followed by 20 mg once daily for a further five days.

In the treatment of chronic disorders: The therapeutic effect of tenoxicam is evident early in treatment but there is a progressive increase in response over time. In chronic disorders, daily doses higher than 20 mg should be avoided since this would increase the frequency and intensity of unwanted reactions without significantly increasing efficacy. For patients needing long-term treatment, a reduction to a daily oral dose of 10 mg may be tried for maintenance.

Special dosage instructions: In principle, the above dosage recommendations also apply to elderly patients and to patients suffering from kidney or liver disease. Because of lack of clinical experience, no dosage recommendations have so far been established for children and adolescents.

The tablets should be taken with a glass of water. It is preferable to take this medicine during or immediately after a meal.

Based on clinical trials including large numbers of patients, Tenoxicam proved to be well tolerated in the recommended dose. Usually, the undesirable effects reported were mild and transient. In a small proportion of patients, the interruption of treatment due to undesirable effects was necessary. Local tolerance of Tenoxicam given parenterally was good. The following undesirable effects have been reported:

Frequency is greater than 1%-

• Gastrointestinal tract: gastric, epigastric and abdominal discomfort, dyspepsia, heartburn, nausea.
• Central nervous system: dizziness, headache.

Frequency less than 1%-

• Gastrointestinal tract: constipation, diarrhea, stomatitis, gastritis, vomiting, ulcers, Gl-bleeding including hematemesis and melena.
• Central nervous system: fatigue, sleep disturbances, appetite loss, dry mouth, vertigo.
• Skin: itching (also in the anal region after rectal administration), erythema, exanthema, rash, urticaria.
• Urinary tract and kidneys: increase in BUN or creatinine, edema.
• Liver and biliary tract: increased liver enzyme activity.
• Cardiovascular system: palpitations.

Isolated cases (frequency less than 0.01%)-

• Gastrointestinal tract: Gl-perforation.
• Central nervous system: visual disturbances.
• Skin: Stevens-Johnson and Lyell's syndrome, photosensitivity reaction, vasculitis.
• Blood: anemia, agranulocytosis, leukopenia, thrombocytopenia.
• Hypersensitivity reactions: dyspnea, asthma, anaphylaxis, angioedema.
• Cardiovascular system: elevated blood pressure, mainly in patients treated with cardiovascular drugs.
• Liver/Biliary tract: hepatitis.

Tenoxicam must not be administered to patients:

• known to be hypersensitive to the drug;
• in whom salicylates or other non-steroidal anti-inflammatory drugs (NSAIDs) induce symptoms of asthma, rhinitis, or urticaria;
• suffering or having suffered from the disease of the upper gastrointestinal tract, such as gastritis, gastric and duodenal ulcer.

NSAIDs inhibit renal prostaglandin synthesis and consequently may have an undesirable effect on renal hemodynamics and on salt and water balance. It is necessary to adequately monitor the patient with a special emphasis on cardiac and renal function (BUN, creatinine, development of edema, weight gain, etc.) when giving Tenoxicam to patients with conditions that could increase their risk of developing renal failure, such as pre-existing renal disease, impaired renal function in diabetics, hepatic cirrhosis, congestive heart failure, volume depletion or concomitant treatment with potentially nephrotoxic drugs, diuretics and corticosteroids. Tenoxicam inhibits platelet aggregation and may affect hemostasis. Tenoxicam has no significant influence on blood coagulation factors, coagulation time, prothrombin time or activated thromboplastin time. Patients having coagulation disorders or receiving drug therapy that interferes with hemostasis should, however, be carefully observed when Tenoxicam is administered. Any patient being treated with Tenoxicam who presents with symptoms of gastrointestinal disease should be closely monitored. If peptic ulceration or gastrointestinal bleeding occurs, Tenoxicam should be immediately withdrawn. If severe skin reactions (e.g. Lyell's or Stevens-Johnson syndrome) occur, the treatment should be discontinued immediately. Adverse eye findings have been reported with Tenoxicam. Thus ophthalmic evaluation is recommended for patients who develop visual disturbances. Because of the high plasma protein binding of tenoxicam, caution is required when plasma albumin levels are markedly reduced. In common with anti-inflammatory drugs, Tenoxicam may mask the usual signs of infection. Tenoxicam Tablets should not be given to patients who either dislike or do not tolerate milk products.

As in the case of other NSAIDs, salicylate displaces tenoxicam from protein-binding sites and increases clearance and volume of distribution of tenoxicam. Concurrent treatment with salicylate or other NSAIDs should be avoided because of increased risk of gastrointestinal undesirable reactions. The co-administration of some NSAIDs and methotrexate has been associated with reduced renal tubular secretion of methotrexate, higher plasma concentrations of methotrexate, and severe methotrexate toxicity. Therefore, caution should be exercised when Tenoxicam is administered concurrently with methotrexate. No clinically relevant interaction was found in the small number of patients receiving concomitant treatment with gold, penicillamine or probenecid. As Tenoxicam may decrease the renal clearance of lithium, their concomitant administration may lead to increased plasma levels and toxicity of lithium. The plasma levels of lithium should be closely monitored. As with NSAIDs in general, Tenoxicam should not be administered concurrently with K-sparing diuretics. There is a known interaction between these two classes of compounds, which may cause hyperkalemia and renal failure. No clinically significant interaction between Tenoxicam and furosemide was noted, but Tenoxicam attenuates the blood pressure-lowering effect of hydrochlorothiazide. As known from other NSAIDs, Tenoxicam might attenuate the antihypertensive effects of alpha-adrenergic blockers and ACE-inhibitors. No interactions have been reported between NSAIDs and centrally-acting alpha agonists or calcium channel blockers. There was no clinically relevant interaction when Tenoxicam was administered together with atenolol. During clinical trials no interaction was reported for patients treated concomitantly with digitalis products. Thus concurrent dosing of Tenoxicam and digoxin appears to be without major risk. No interaction has been found with concomitantly administered antacids, cimetidine, warfarin and phenprocoumon at the recommended dosages. The clinical effect of oral antidiabetic drugs (glibornuride, glibenclamide, tolbutamide) was likewise not modified by Tenoxicam. Nevertheless, careful monitoring is recommended when patients concomitantly receive anticoagulants or oral antidiabetic drugs. No clinically relevant interaction has been found between Tenoxicam and low molecular weight heparin.

NSAIDs have an inhibitory effect on prostaglandin synthesis and, when given during late pregnancy, may cause the closure of the fetal ductus arteriosus, prolong labor and delay parturition. Treatment during the third trimester of pregnancy should be avoided. Based on findings from single-dose administration, a very small amount (approximately 0.2%) of tenoxicam passes into breast milk. There is no evidence of adverse reactions in breast-fed infants of mothers taking Tenoxicam. Nevertheless, infants should be weaned or the drug discontinued.

Use in Children & adolescent: Tenoxicam is not recommended for use in patients under 16 years of age, as the dose and indications in this population have not been established.

Effects on ability to drive and use machines: Patients experiencing adverse events that might affect driving or using machines, such as vertigo, dizziness or visual disturbances should refrain from driving a car or using machines.

Although there is no experience of acute overdosage with Tenoxicam, it may be expected that the signs and symptoms mentioned under Undesirable effects would be more pronounced. Overdose should be countered by conventional measures to reduce absorption (e.g. gastrolavage and charcoal) and speed up elimination (e.g. cholestyramine).

Do not store above 30°C, protect from light & moisture. Keep out of the reach of children.

This is indicated in-

• Patients with essential hypertension
• Patients with angina pectoris & hypertension as co-existing diseases
• ln post Ml patients
• ln patients with refractory angina pectoris where nitrate therapy has failed.

Combined antihypertensive preparations

This is a fixed-dose combination of Amlodipine and Atenolol. Amlodipine is a dihydropyridine calcium antagonist that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle; it has a greater effect on vascular smooth muscle than on cardiac muscle. Amlodipine is a peripheral vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and reduction in blood pressure. Amlodipine reduces tone, decreases coronary vasoreactivity and lowers cardiac demand by reducing afterload.

Atenolol is a cardioselective beta-blocker. The cardio-selectivity is dose-related. Atenolol causes a reduction in blood pressure by lowering cardiac output, decreasing the plasma renin activity and sympathetic outflow from CNS. Atenolol also causes a reduction in myocardial oxygen demand by virtue of its negative inotropic and negative chronotropic effects.

The recommended dosage is Amlodipine and Atenolol 5/25 mg tablet once daily. If necessary, the dosage may be increased to 5/25 mg two tablets daily or as advised by the physicians. The dosage however should be individualized.

The combination of Amlodipine and Atenolol is well tolerated. Overall side-effects include
fatigue, headache, edema, nausea, drowsiness, anxiety and depression.

Hypersensitivity to either component, sinus bradycardia, second and higher degrees of heart block, cardiogenic shock, hypotension, congestive heart failure, poor left ventricular function.

Bronchospasm: The combination should be used with caution in patients with airway obstruction.

Renal impairment: The combination can be used in patients with renal impairment. However, caution may be necessary if the creatinine clearance is less than 30 ml/min because of possible reduction in the excretion of unchanged Atenolol.

Hepatic impairment: Caution may be necessary in the use of the combination in patients with severe liver damage because of prolongation of the elimination half-life of Amlodipine.

Drug withdrawal: Since coronary heart disease may exist without being recognized, patients should be warned against stopping the drug suddenly. Any discontinuation should be gradual and under observation.

Disopyramide: Atenolol reduces the clearance of disopyramide by 20%. Additive negative inotropic effects on the heart may be produced.

Ampicillin: at doses of 1 gm and above may reduce Atenolol levels.

Oral antidiabetics and insulin: Beta-blockers may decrease tissue sensitivity to insulin and inhibit insulin secretion e.g. in response to oral antidiabetics. Atenolol has less potential for these actions.

The combination should be used during pregnancy only if the expected benefit outweighs the potential fetal risk. The combination should not be used by nursing mothers. If its use is considered necessary, breast-feeding should be stopped.

Though not documented, hypotension and less frequently congestive cardiac failure may occur in cases of overdosage. Unabsorbed drugs may be removed by gastric lavage or administration of activated charcoal. Symptomatic treatment is suggested.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

Atenolol is indicated-

• In the management of hypertension. It may be used alone or concomitantly with other antihypertensive agents, particularly with a thiazide-type diuretic.
• For the long-term management of patients with angina pectoris.
• In the management of hemodynamically stable patients with defnite or suspected acute myocardial infarction to reduce cardiovascular mortality.

Beta-adrenoceptor blocking drugs, Beta-blockers

The synthesis of atenolol resulted from attempts to produce a β-adrenoceptor antagonist that would competitively block β1 (cardiac) receptors but have no effect on β2-receptors. It is classified as a β1 selective (cardioselective) β-adrenergic receptor antagonist with no membranestability activity and no partial agonist activity. It is markedly the most hydrophilic of the currently available β- blockers and thus penetrates the lipid of cell membranes poorly

Hypertension: The initial dose of Atenolol is 50 mg given as one tablet a day either alone or added to diuretic therapy. The full effect of this dose will usually be seen within one to two weeks. If an optimal response is not achieved, the dosage should be increased to Atenolol 100 mg given as one tablet a day. Increasing the dosage beyond 100 mg a day is unlikely to produce any further benefit.

Angina Pectoris: The initial dose of Atenolol is 50 mg given as one tablet a day. If an optimal response is not achieved within one week, the dosage should be increased to Atenolol 100 mg given as one tablet a day. Some patients may require a dosage of 200 mg once a day for optimal effect. Twenty-four hour control with once daily dosing is achieved by giving doses larger than necessary to achieve an immediate maximum effect. The maximum early effect on exercise tolerance occurs with doses of 50 to 100 mg, but at these doses the effect at 24 hours is attenuated, averaging about 50% to 75% of that observed with once a day oral doses of 200 mg.

Acute Myocardial Infarction: In patients with definite or suspected acute myocardial infarction, treatment with Atenolol I.V. Injection should be initiated as soon as possible after the patient's arrival in the hospital and after eligibility is established. Treatment should begin with the intravenous administration of 5 mg Atenolol over 5 minutes followed by another 5 mg intravenous injection 10 minutes later. In patients who tolerate the full intravenous dose (10 mg), Atenolol Tablets 50 mg should be initiated 10 minutes after the last intravenous dose followed by another 50 mg oral dose 12 hours later. Thereafter, Atenolol can be given orally either 100 mg once daily or 50 mg twice a day for a further 6-9 days or until discharge from the hospital. If bradycardia or hypotension requiring treatment or any other untoward effects occur, Atenolol should be discontinued.

In a series of investigations in the treatment of acute myocardial infarction, bradycardia and hypotension occurred more commonly, as expected for any beta blocker. In addition, a variety of adverse efects has been reported with other beta-adrenergic blocking agents, and may be considered potential adverse efects of Atenolol.

• Hematologic: Agranulocytosis.
• Allergic: Fever, combined with aching and sore throat, laryngospasm, and respiratory distress.
• Central Nervous System: Reversible mental depression progressing to catatonia; an acute reversible syndrome characterized by disorientation of time and place; short term memory loss; emotional lability with slightly clouded sensorium; and, decreased performance on neuropsychometrics.
• Gastrointestinal: Mesenteric arterial thrombosis, ischemic colitis.
• Miscellaneous: There have been reports of skin rashes and/or dry eyes associated with the use of beta-adrenergic blocking drugs. Discontinuance of the drug should be considered if any such reaction is not otherwise explicable. Patients should be closely monitored following cessation of therapy.
• Other: Erythematous rash

Atenolol is contraindicated in-

• Sinus bradycardia, heart block greater than first degree, cardiogenic shock, and overt cardiac failure.
• Those patients with a history of hypersensitivity to the atenolol or any of the drug product’s components.

General: Patients already on a beta blocker must be evaluated carefully before Atenolol is administered. Initial and subsequent Atenolol dosages can be adjusted downward depending on clinical observations including pulse and blood pressure. Atenolol may aggravate peripheral arterial circulatory disorders.

Impaired Renal Function: The drug should be used with caution in patients with impaired renal function.

Geriatric Use:

• Hypertension and Angina Pectoris: Due to Coronary Atherosclerosis: Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
• Acute Myocardial Infarction: Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Evaluation of patients with hypertension or myocardial infarction should always include assessment of renal function.

Pregnancy Category D. Caution should be exercised when Atenolol is administered to a nursing woman. Clinically significant bradycardia has been reported in breast-fed infants. Premature infants, or infants with impaired renal function, may be more likely to develop adverse effects.

Elderly Patients or Patients with Renal Impairment: Atenolol is excreted by the kidneys; consequently dosage should be adjusted in cases of severe impairment of renal function. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, refecting greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. The following maximum oral dosages are recommended for elderly, renal impaired patients and for patients with renal impairment due to other causes:

• Creatinine clearance 15-35 ml/min/1.73 m²: Maximum dosage 50 mg daily
• Creatinine clearance <15 mL/min/1.73 m²: Maximum dosage 25 mg daily

Some renal impaired or elderly patients being treated for hypertension may require a lower starting dose of Atenolol: 25 mg given as one tablet a day. Patients on hemodialysis should be given 25 mg or 50 mg after each dialysis; this should be done under hospital supervision as marked falls in blood pressure can occur.

The predominant symptoms reported following Atenolol overdose are lethargy, disorder of respiratory drive, wheezing, sinus pause and bradycardia. Additionally, common efects associated with overdosage of any beta-adrenergic blocking agent and which might also be expected in Atenolol overdose are congestive heart failure, hypotension, bronchospasm and/or hypoglycemia. Treatment of overdose should be directed to the removal of any unabsorbed drug by induced emesis, gastric lavage, or administration of activated charcoal. Atenolol can be removed from the general circulation by hemodialysis. Based on the severity of symptoms, management may require intensive support care and facilities for applying cardiac and respiratory support.

Do not use later than the date of expiry. Keep all medicines out of the reach of children. To be dispensed only on the prescription of a registered physician.

This combination is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure lowers the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions.

Combined antihypertensive preparations

Atenolol and chlorthalidone have been used singly and concomitantly for the treatment of hypertension. Studies have shown that there is no interference with bioavailability when these agents are given together in the single combination tablet. Therefore, this combination provides a convenient formulation for the concomitant administration of these two drugs.

Atenolol is a beta1-selective (cardioselective) beta-adrenergic receptor blocking agent that provides-

• reduction in resting and exercise heart rates and cardiac output
• reduction of systolic and diastolic blood pressure at rest and on exercise
• reduction in reflex orthostatic tachycardia.

Chlorthalidone is a monosulfonamyl diuretic with prolonged action and low toxicity. It produces diuresis with greatly increased excretion of sodium and chloride at distal convoluted tubule of the nephron.

The initial dose is Atenolol 50 mg and Chlorthalidone 25 mg once a day. If an optimal response is not achieved, another antihypertensive agent may be added gradually beginning with 50 percent of the usual recommended starting dose to avoid an excessive fall in blood pressure. Atenolol is excreted via kidneys and therefore dosage should be adjusted in cases of severe impairment of renal function.

Use in elderly: Clinical studies of Atenolol & Chlorthalidone combination did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

The adverse effects observed for this combination are essentially the same as those seen with the individual components. Atenolol: Bradycardia, Cold Extremities, Postural Hypotension, Leg Pain, Dizziness, Vertigo, Light Headedness, Tiredness, Fatigue, Lethargy, Drowsiness, Depression, Dreaming, Diarrhea, Nausea, Wheeziness, Dyspnea, Chlorthalidone Orthostatic hypotension, anorexia, gastric irritation, vomiting, cramping, constipation, vertigo, purpura, photosensitivity, rash, urticaria, hyperglycemia, glycosuria, hyperuricemia, muscle spasm, weakness, restlessness.

Atenolol and Chlorthalidone combination is contraindicated in hypersensitivity to this product or to sulfonamide-derived drugs. It is also contraindicated in patients with sinus bradycardia, heart block greater than first degree, cardiogenic shock, overt cardiac failure and anuria.

This combination may aggravate peripheral arterial circulatory disorders. Periodic determination of serum electrolytes to detect possible electrolyte imbalance should be performed at appropriate intervals.

Pregnancy Category D. Caution should be exercised when this drug is administered to a woman who is breastfeeding.

No specific information is available with regard to overdosage of this combination in humans. Treatment should be symptomatic and supportive and directed to the removal of any unabsorbed drug by induced emesis, or administration of activated charcoal. Atenolol can be removed from the general circulation by hemodialysis. Further consideration should be given to dehydration, electrolyte imbalance and hypotension by established procedures.

Store in cool and dry place, protected from light.

Tenoxicam is indicated for the symptomatic treatment of the following painful inflammatory and degenerative disorders of the musculoskeletal system:

• Rheumatoid arthritis.
• Osteoarthritis.
• Arthrosis.
• Ankylosing spondylitis.
• Extra-articular disorders, e.g. tendinitis, bursitis, periarthritis of the shoulders (shoulder-hand syndrome) or hips, strains, and sprains.
• Acute gout.

Drugs for Osteoarthritis, Drugs used for Rheumatoid Arthritis, Non-steroidal Anti-inflammatory Drugs (NSAIDs)

Tenoxicam is a non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic and antipyretic properties and it also inhibits platelet aggregation. Tenoxicam inhibits prostaglandin biosynthesis. In-vitro tests of leukocyte peroxidase suggest that tenoxicam may act as a scavenger for active oxygen at the site of inflammation. Tenoxicam is a potent in-vitro inhibitor of human metalloproteinases (stromelysin and collagenase), which induce cartilage breakdown. These pharmacological effects explain, at least in part, the therapeutic benefit of Tenoxicam in the treatment of painful inflammatory and degenerative disorders of the musculoskeletal system. Tenoxicam showed no mutagenic, carcinogenic or teratogenic effects in animals. As with other prostaglandin inhibitors, renal and gastrointestinal effects, increased incidence of dystocia and delayed parturition were observed in animal safety studies.

Standard dosage: For all indications except acute gout, a daily dosage of 20 mg should be given at the same time of day.

In acute attacks of gout: The recommended dose for acute attacks of gout is 40 mg once daily for two days followed by 20 mg once daily for a further five days.

In the treatment of chronic disorders: The therapeutic effect of tenoxicam is evident early in treatment but there is a progressive increase in response over time. In chronic disorders, daily doses higher than 20 mg should be avoided since this would increase the frequency and intensity of unwanted reactions without significantly increasing efficacy. For patients needing long-term treatment, a reduction to a daily oral dose of 10 mg may be tried for maintenance.

Special dosage instructions: In principle, the above dosage recommendations also apply to elderly patients and to patients suffering from kidney or liver disease. Because of lack of clinical experience, no dosage recommendations have so far been established for children and adolescents.

The tablets should be taken with a glass of water. It is preferable to take this medicine during or immediately after a meal.

Based on clinical trials including large numbers of patients, Tenoxicam proved to be well tolerated in the recommended dose. Usually, the undesirable effects reported were mild and transient. In a small proportion of patients, the interruption of treatment due to undesirable effects was necessary. Local tolerance of Tenoxicam given parenterally was good. The following undesirable effects have been reported:

Frequency is greater than 1%-

• Gastrointestinal tract: gastric, epigastric and abdominal discomfort, dyspepsia, heartburn, nausea.
• Central nervous system: dizziness, headache.

Frequency less than 1%-

• Gastrointestinal tract: constipation, diarrhea, stomatitis, gastritis, vomiting, ulcers, Gl-bleeding including hematemesis and melena.
• Central nervous system: fatigue, sleep disturbances, appetite loss, dry mouth, vertigo.
• Skin: itching (also in the anal region after rectal administration), erythema, exanthema, rash, urticaria.
• Urinary tract and kidneys: increase in BUN or creatinine, edema.
• Liver and biliary tract: increased liver enzyme activity.
• Cardiovascular system: palpitations.

Isolated cases (frequency less than 0.01%)-

• Gastrointestinal tract: Gl-perforation.
• Central nervous system: visual disturbances.
• Skin: Stevens-Johnson and Lyell's syndrome, photosensitivity reaction, vasculitis.
• Blood: anemia, agranulocytosis, leukopenia, thrombocytopenia.
• Hypersensitivity reactions: dyspnea, asthma, anaphylaxis, angioedema.
• Cardiovascular system: elevated blood pressure, mainly in patients treated with cardiovascular drugs.
• Liver/Biliary tract: hepatitis.

Tenoxicam must not be administered to patients:

• known to be hypersensitive to the drug;
• in whom salicylates or other non-steroidal anti-inflammatory drugs (NSAIDs) induce symptoms of asthma, rhinitis, or urticaria;
• suffering or having suffered from the disease of the upper gastrointestinal tract, such as gastritis, gastric and duodenal ulcer.

NSAIDs inhibit renal prostaglandin synthesis and consequently may have an undesirable effect on renal hemodynamics and on salt and water balance. It is necessary to adequately monitor the patient with a special emphasis on cardiac and renal function (BUN, creatinine, development of edema, weight gain, etc.) when giving Tenoxicam to patients with conditions that could increase their risk of developing renal failure, such as pre-existing renal disease, impaired renal function in diabetics, hepatic cirrhosis, congestive heart failure, volume depletion or concomitant treatment with potentially nephrotoxic drugs, diuretics and corticosteroids. Tenoxicam inhibits platelet aggregation and may affect hemostasis. Tenoxicam has no significant influence on blood coagulation factors, coagulation time, prothrombin time or activated thromboplastin time. Patients having coagulation disorders or receiving drug therapy that interferes with hemostasis should, however, be carefully observed when Tenoxicam is administered. Any patient being treated with Tenoxicam who presents with symptoms of gastrointestinal disease should be closely monitored. If peptic ulceration or gastrointestinal bleeding occurs, Tenoxicam should be immediately withdrawn. If severe skin reactions (e.g. Lyell's or Stevens-Johnson syndrome) occur, the treatment should be discontinued immediately. Adverse eye findings have been reported with Tenoxicam. Thus ophthalmic evaluation is recommended for patients who develop visual disturbances. Because of the high plasma protein binding of tenoxicam, caution is required when plasma albumin levels are markedly reduced. In common with anti-inflammatory drugs, Tenoxicam may mask the usual signs of infection. Tenoxicam Tablets should not be given to patients who either dislike or do not tolerate milk products.

As in the case of other NSAIDs, salicylate displaces tenoxicam from protein-binding sites and increases clearance and volume of distribution of tenoxicam. Concurrent treatment with salicylate or other NSAIDs should be avoided because of increased risk of gastrointestinal undesirable reactions. The co-administration of some NSAIDs and methotrexate has been associated with reduced renal tubular secretion of methotrexate, higher plasma concentrations of methotrexate, and severe methotrexate toxicity. Therefore, caution should be exercised when Tenoxicam is administered concurrently with methotrexate. No clinically relevant interaction was found in the small number of patients receiving concomitant treatment with gold, penicillamine or probenecid. As Tenoxicam may decrease the renal clearance of lithium, their concomitant administration may lead to increased plasma levels and toxicity of lithium. The plasma levels of lithium should be closely monitored. As with NSAIDs in general, Tenoxicam should not be administered concurrently with K-sparing diuretics. There is a known interaction between these two classes of compounds, which may cause hyperkalemia and renal failure. No clinically significant interaction between Tenoxicam and furosemide was noted, but Tenoxicam attenuates the blood pressure-lowering effect of hydrochlorothiazide. As known from other NSAIDs, Tenoxicam might attenuate the antihypertensive effects of alpha-adrenergic blockers and ACE-inhibitors. No interactions have been reported between NSAIDs and centrally-acting alpha agonists or calcium channel blockers. There was no clinically relevant interaction when Tenoxicam was administered together with atenolol. During clinical trials no interaction was reported for patients treated concomitantly with digitalis products. Thus concurrent dosing of Tenoxicam and digoxin appears to be without major risk. No interaction has been found with concomitantly administered antacids, cimetidine, warfarin and phenprocoumon at the recommended dosages. The clinical effect of oral antidiabetic drugs (glibornuride, glibenclamide, tolbutamide) was likewise not modified by Tenoxicam. Nevertheless, careful monitoring is recommended when patients concomitantly receive anticoagulants or oral antidiabetic drugs. No clinically relevant interaction has been found between Tenoxicam and low molecular weight heparin.

NSAIDs have an inhibitory effect on prostaglandin synthesis and, when given during late pregnancy, may cause the closure of the fetal ductus arteriosus, prolong labor and delay parturition. Treatment during the third trimester of pregnancy should be avoided. Based on findings from single-dose administration, a very small amount (approximately 0.2%) of tenoxicam passes into breast milk. There is no evidence of adverse reactions in breast-fed infants of mothers taking Tenoxicam. Nevertheless, infants should be weaned or the drug discontinued.

Use in Children & adolescent: Tenoxicam is not recommended for use in patients under 16 years of age, as the dose and indications in this population have not been established.

Effects on ability to drive and use machines: Patients experiencing adverse events that might affect driving or using machines, such as vertigo, dizziness or visual disturbances should refrain from driving a car or using machines.

Although there is no experience of acute overdosage with Tenoxicam, it may be expected that the signs and symptoms mentioned under Undesirable effects would be more pronounced. Overdose should be countered by conventional measures to reduce absorption (e.g. gastrolavage and charcoal) and speed up elimination (e.g. cholestyramine).

Do not store above 30°C, protect from light & moisture. Keep out of the reach of children.
