Angiotensin-converting enzyme (ACE) inhibitors

Ramipril is an angiotensin converting enzyme (ACE) inhibitor, which after hydrolysis to ramiprilat, blocks the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. So, inhibition of ACE by ramipril results in decreased plasma angiotensin II, which leads to decreased vasopressor activity and decreased aldosterone secretion. Thus ramipril exerts its antihypertensive activity. It is also effective in the management of heart failure and reduction of the risk of stroke, myocardial infarction and death from cardiovascular events. It is long acting and well tolerated; so, can be used in long term therapy.

Dosage of Ramipril must be adjusted according to the patient tolerance and response.

Hypertension: For the management of hypertension in adults not receiving a diuretic, the usual initial dose of Ramipril is 1.25-2.5 mg once daily. Dosage generally is adjusted no more rapidly than at 2 week intervals. The usual maintenance dosage in adults is 2.5-20 mg daily given as a single dose or in 2 divided doses daily. If BP is not controlled with Ramipril alone, a diuretic may be added.

Congestive heart failure after myocardial infarction: In this case, Ramipril therapy may be initiated as early as 2 days after myocardial infarction. An initial dose of 2.5 mg twice daily is recommended, but if hypotension occurs, dose should be reduced to 1.25 mg twice daily. Therapy is then titrated to a target daily dose of 5 mg twice daily.

Prevention of major cardiovascular events: In this case, the recommended dose is 2.5 mg once daily for the first week of therapy and 5 mg once daily for the following 3 weeks; dosage then may be increased, as tolerated, to a maintenance dosage of 10 mg once daily.

Dosage in renal impairment:

• For patients with hypertension and renal impairment: The recommended initial dose is 1.25 mg Ramipril once daily. Subsequent dosage should be titrated according to individual tolerance and BP response, up to a maximum of 5 mg daily.
• For patients with heart failure and renal impairment: The recommended dose is 1.25 mg once daily. The dose may be increased to 1.25 mg twice daily and up to a maximum dose of 2.5 mg twice daily depending upon clinical response and tolerability.

Ramipril tablets have to be swallowed with sufficient amounts of liquid. The tablets must not be chewed or crushed. Absorption of Ramipril is not significantly affected by food. Ramipril may, therefore, be taken before, during or after a meal.

Ramipril is generally well tolerated. Dizziness, headache, fatigue and asthenia are commonly reported side effects. Other side effects occurring less frequently include symptomatic hypotension, cough, nausea, vomiting, diarrhoea, rash, urticaria, oliguria, anxiety, amnesia etc. Angioneurotic oedema, anaphylactic reactions and hyperkalaemia have also been reported rarely.

Ramipril must not be used

• in patients with hypersensitivity to ramipril, to any other ACE inhibitor, or any of the excipients of Ramipril.
• in patients with a history of angioedema.
• concomitantly with sacubitril/valsartan therapy. Do not initiate Ramipril until sacubitril/valsartan is eliminated from the body. In case of switch from Ramipril to sacubitril/valsartan, do not start sacubitril/valsartan until Ramipril is eliminated from the body.
• in patients with haemodynamically relevant renal artery stenosis, bilateral or unilateral in the single kidney.
• in patients with hypotensive or haemodynamically unstable states.
• with aliskiren-containing medicines in patients with diabetes or with moderate to severe renal impairment (creatinine clearance <60 ml/min).
• with angiotensin II receptor antagonists (AIIRAs) in patients with diabetic nephropathy.
• during pregnancy.

Concomitant use of ACE inhibitors and extracorporeal treatments leading to contact of blood with negatively charged surfaces must be avoided, since such use may lead to severe anaphylactoid reactions. Such extracorporeal treatments include dialysis or haemofiltration with certain high-fux (e.g. polyacrylonitril) membranes and low-density lipoprotein apheresis with dextran sulfate.

Ramipril should be used with caution in patients with impaired renal function, hyperkalaemia, hypotension, and impaired hepatic function.

Concomitant administration with diuretics may lead to serious hypotension and in addition dangerous hyperkalemia with potassium sparing diuretics. Concomitant therapy with lithium may increase the serum lithium concentration. Reduction in BP may affect the ability to drive and operate machinery and this may be exacerbated by alcohol. NSAIDs may reduce the antihypertensive effect of Ramipril and cause deterioration of renal function.

Ramipril must not be taken during pregnancy. Therefore, pregnancy must be excluded before starting treatment. Pregnancy must be avoided in cases where treatment with ACE inhibitors is indispensable. If the patient intends to become pregnant, treatment with ACE inhibitors must be discontinued, i.e. replaced by another form of treatment. If the patient becomes pregnant during treatment, medication with Ramipril must be replaced as soon as possible by a treatment regimen without ACE inhibitors. Otherwise, there is a risk of harm to the fetus. Ramipril is not recommended during breastfeeding.

Elderly: A reduced initial dose of 1.25 mg Ramipril daily must be considered.

Hepatic impairment: Treatment in these patients must therefore be initiated only under close medical supervision. The maximum permitted daily dose in such cases is 2.5 mg Ramipril.

Renal impairment: With a creatinine clearance between 50 and 20 ml/min per 1.73 m2 body surface area, the initial daily dose is generally 1.25 mg Ramipril. The maximum permitted daily dose, in this case, is 5 mg Ramipril. Patients with incompletely corrected fuid or salt depletion, in patients with severe hypertension, as well as in patients in whom a hypotensive reaction would constitute a particular risk, (e.g., with relevant stenoses of the coronary vessels or those supplying the brain) A reduced initial dose of 1.25 mg Ramipril daily must be considered.

Patients pretreated with a diuretic: Consideration must be given to discontinuing the diuretic for at least 2 to 3 days or- depending on the duration of action of the diuretic- longer before starting treatment with Ramipril, or at least to reducing the diuretic dose. The initial daily dose in patients previously treated with a diuretic is generally 1.25 mg Ramipril.

Sign and symptom: Overdosage may cause excessive peripheral vasodilatation (with marked hypotension, shock), bradycardia, electrolyte disturbances, and renal failure.

Management: Primary detoxifcation by, for example, gastric lavage, administration of adsorbents, sodium sulfate; (if possible during the frst 30 minutes). In the event of hypotension administration of α1-adrenergic agonists (e.g. norepinephrine, dopamine) or angiotensin II (angiotensinamide), which is usually available only in scattered research laboratories, must be considered in addition to volume and salt substitution.

Indicated for the treatment of mild to moderate hypertension in patients (in whom combination therapy is appropriate) who have been stabilised on the individual components given in the same proportion.

Combined antihypertensive preparations

Ramipril is an angiotensin converting enzyme (ACE) inhibitor, which after hydrolysis to ramiprilat, blocks the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. So, inhibition of ACE by ramipril results in decreased plasma angiotensin II, which leads to decreased vasopressor activity and decreased aldosterone secretion. Thus ramipril exerts its antihypertensive activity. It is also effective in the management of heart failure and reduction of the risk of stroke, myocardial infarction and death from cardiovascular events. It is long acting and well tolerated; so, can be used in long term therapy.

Hydrochlorothiazide is a thiazide diuretic. Thiazides affect the renal tubular mechanisms of electrolyte reabsorption, directly increasing excretion of sodium and chloride in approximately equivalent amounts. Indirectly, the diuretic action of Hydrochlorothiazide reduces plasma volume, with consequent increases in plasma renin activity, increases in aldosterone secretion, increases in urinary potassium loss, and decreases in serum potassium. The renin-aldosterone link is mediated by angiotensin II, so co-administration of anangiotensin converting enzyme (ACE) inhibitor tends to reverse the potassium loss associated with these diuretics.

Dose Titration Guided by Clinical Effect. A patient whose blood pressure is not adequately controlled with ramipril (or another ACE inhibitor) alone or with hydrochlorothiazide (or another thiazide diuretic) alone may be switched to combination therapy with Ramipril 2.5 mg + Hydrochlorothiazide 12.5 mg or Ramipril 5 mg + Hydrochlorothiazide 25 mg tablet.

Replacement Therapy: For convenience, patients receiving ramipril and hydrochlorothiazide from separate tablets may instead wish to receive tablets of combination of Ramipril 2.5 mg + Hydrochlorothiazide 12.5 mg or Ramipril 5 mg + Hydrochlorothiazide 25 mg. If necessary, the dose may be increased to two tablets of Ramipril 2.5 mg + Hydrochlorothiazide 12.5 mg or Ramipril 5 mg + Hydrochlorothiazide 25 mg once daily.

Maximum daily dose: 10 mg ramipril and 50 mg hydrochlorothiazide (four tablets of Ramipril 2.5 mg + Hydrochlorothiazide 12.5 mg or two tablets of Ramipril 5 mg + Hydrochlorothiazide 25 mg).

The combination of Ramipril and Hydrochlorothiazide is generally well tolerated. Side effects commonly reported include headache, dizziness, asthenia, nausea, vomiting, hypotension, cough, weakness, diarrhoea, fever, gastric irritation, pulmonary oedema, photosensitivity, electrolyte imbalance, hyperglycaemia, hyperuricaemia and vertigo.

This preparation must not be used in patients with hypersensitivity to ramipril, hydrochlorothiazide or other thiazide diuretics. History of hereditary angioneurotic oedema. Severe impairment of renal function. Haemodynamically relevant unilateral or bilateral renal artery stenosis, mitral stenosis, aortic stenosis, and in patients with low blood pressure (hypotensive patients) or in patients with an unstable circulatory situation (haemodynamically unstable patients) where there might be a risk of life-threatening fall in blood pressure and renal failure. Clinically relevant electrolyte disturbances e.g. hypokalemia, hyponatremia or hypercalcemia which may worsen following treatment.

Treatment with Ramipril and Hydrochlorothiazide combination requires regular medical supervision. Generally dehydration, reduced blood volume (hypovolumia) or salt depletion should be corrected before initiating the treatment (in patients with concomitant heart failure, however, this must be carefully weighed against the risk of volume overload).

Special caution is necessary during the treatment of: Patients with severe and particularly with malignant hypertension. Patients with concomitant and particularly with severe heart failure. Patients in whom fluid or salt deficiency exists or may develop (as a result of inadequate fluid or salt intake) or as a result of diarrhoea, vomiting or excessive sweating in cases where salt and fluid replacement is inadequate. Patients with haemodynamically relevant renal artery stenosis. In patients with pre-existing impairment of renal function or in kidney transplant patients. White blood cell count should be monitored (more frequent in the initial phase of the treatment) so that leucopenia can be detected. Insufficient experience has been gained concerning the use of Ramipril and Hydrochlorothiazide combination in children.

Combination with diuretics or other antihypertensive agents or nitrates and tricyclic antidepressants may potentiate the antihypertensive response to Ramipril and Hydrochlorothiazide combination. Patients previously treated with diuretics may experience a marked drop in blood pressure. Ramipril / Hydrochlorothiazide may weaken the effectiveness of blood sugar lowering medications (antidiabetic agents, e.g. insulin and sulphonylurea derivatives). When Ramipril/Hydrochlorothiazide is administered simultaneously with acetyl salicylic acid or indomethacin, attenuation of antihypertensive effect and moreover acute renal failure may occur. Ramipril / Hydrochlorothiazide may potentiate the effects of alcohol.

ACE inhibitors can cause foetal and neonatal morbidity and death when administered to pregnant women. Also, thiazides cross the placental barrier and appear in cord blood. There is a risk of foetal or neonatal jaundice, thrombocytopenia, and possibly other adverse reactions that have occurred in adults. When pregnancy is detected, Ramipril and Hydrochlorothiazide combination should be discontinued as soon as possible. This product is excreted in breast milk. Because of the potential for serious adverse reactions in nursing infants, women receiving Ramipril and Hydrochlorothiazide combination should not breast feed.

Dosage in renal impairment: In patients with a creatinine clearance between 60 and 30 ml/min, treatment should be initiated with Ramipril 1.25 mg monotherapy. If blood pressure is not adequately controlled, the dose of Ramipril may be increased to 2.5 mg. If blood pressure is still not controlled, patient may be switched to one tablet of Ramoril 2.5 Plus once daily. Dosage may be titrated upward to Ramoril 5 Plus until blood pressure is controlled.

Uue in children: Safety and effectiveness in paediatric patients have not been established

Ramipril: Limited data on human overdosage are available. The most likely clinical manifestations would be symptoms attributable to hypotension. Because the hypotensive effect of Ramipril is achieved through vasodilation and effective hypovolemia, it is reasonable to treat Ramipril overdosage by infusion of normal saline solution.

Hydrochlorothiazide: The most common signs and symptoms observed are those caused by electrolyte depletion (hypokalemia, hypochloremia, and dehydration resulting from excessive diuresis. If digitalis has also been administered, hypokalemia, may accentuate cardiac arrhythmias. The degree to which Hydrochlorothiazide is removed by hemodialysis has not been established.

Chloramphenicol is indicated for the treatment of ocular infections involving the conjunctiva and/or cornea caused by chloramphenicol-susceptible organisms. Such as Staphylococcus aureus, Streptococcus pneumoniae, E.coli, H. influenzae, Klebsiella/Enterobacter spp, Moraxella lacunata, and Neisseria species.

Ear Anti-Infectives & Antiseptics, Eye Anti-Infectives & Antiseptics, Macrolides

Chloramphenicol is a broad-spectrum bacteriostatic antibiotic which acts through the inhibition of bacterial protein synthesis by interfering with the transfer of activated amino acids from soluble RNA to ribosomes.

Adult and Children: Instill 1 or 2 drops in the conjunctival sac 4-6 times per day for the first 72 hours and then every 4 hours thereafter. Treatment should be continued for approximately 7 days, but should not be continued for more than 3 weeks without re-evaluation by the physician.

The systemic adverse reaction has not been observed within short-term topical use of Chloramphenicol. The most frequently reported adverse reactions have been burning, stinging, conjunctival hyperemia, blood dyscrasia, allergic or inflammatory reactions, vesicular and maculopapular dermatitis.

It is contraindicated in individuals with a history of hypersensitivity to Chloramphenicol or any ingredients of the preparation.

Chloramphenicol ophthalmic solution should never be given for minor infections or for prophylaxis. Repeated course and prolonged treatment should be avoided. Blood dyscrasias (granulocytopenia, thrombocytopenia and moderate anaemia) may occur after prolonged ophthalmic use.

Chymotrypsin may be inhibited if given simultaneously with Chloramphenicol.

Safety for use in pregnancy and lactation has not been established. Therefore, use only when considered essential by the physicians.

Accidental ingestion of the medicine is unlikely to cause any toxicity due to low content of antibiotic.

Store in a cool (between 2°C-8°C) and dry place, protect from light, keep out of reach of children. Do not touch the dropper tip to the surface since this may contaminate the solution. Do not use after 30 days of the first opening.

Thus ramipril exerts its antihypertensive activity. It is also effective in the management of heart failure and reduction of the risk of stroke, myocardial infarction and death from cardiovascular events. It is long acting and well tolerated; so, can be used in long term therapy.

Dosage of Ramipril must be adjusted according to the patient tolerance and response.

Hypertension: For the management of hypertension in adults not receiving a diuretic, the usual initial dose of Ramipril is 1.25-2.5 mg once daily. Dosage generally is adjusted no more rapidly than at 2 week intervals. The usual maintenance dosage in adults is 2.5-20 mg daily given as a single dose or in 2 divided doses daily. If BP is not controlled with Ramipril alone, a diuretic may be added.

Congestive heart failure after myocardial infarction: In this case, Ramipril therapy may be initiated as early as 2 days after myocardial infarction. An initial dose of 2.5 mg twice daily is recommended, but if hypotension occurs, dose should be reduced to 1.25 mg twice daily. Therapy is then titrated to a target daily dose of 5 mg twice daily.

Prevention of major cardiovascular events: In this case, the recommended dose is 2.5 mg once daily for the first week of therapy and 5 mg once daily for the following 3 weeks; dosage then may be increased, as tolerated, to a maintenance dosage of 10 mg once daily.

Dosage in renal impairment:

• For patients with hypertension and renal impairment: The recommended initial dose is 1.25 mg Ramipril once daily. Subsequent dosage should be titrated according to individual tolerance and BP response, up to a maximum of 5 mg daily.
• For patients with heart failure and renal impairment: The recommended dose is 1.25 mg once daily. The dose may be increased to 1.25 mg twice daily and up to a maximum dose of 2.5 mg twice daily depending upon clinical response and tolerability.

Ramipril tablets have to be swallowed with sufficient amounts of liquid. The tablets must not be chewed or crushed. Absorption of Ramipril is not significantly affected by food. Ramipril may, therefore, be taken before, during or after a meal.

Ramipril is generally well tolerated. Dizziness, headache, fatigue and asthenia are commonly reported side effects. Other side effects occurring less frequently include symptomatic hypotension, cough, nausea, vomiting, diarrhoea, rash, urticaria, oliguria, anxiety, amnesia etc. Angioneurotic oedema, anaphylactic reactions and hyperkalaemia have also been reported rarely.

Ramipril must not be used

• in patients with hypersensitivity to ramipril, to any other ACE inhibitor, or any of the excipients of Ramipril.
• in patients with a history of angioedema.
• concomitantly with sacubitril/valsartan therapy. Do not initiate Ramipril until sacubitril/valsartan is eliminated from the body. In case of switch from Ramipril to sacubitril/valsartan, do not start sacubitril/valsartan until Ramipril is eliminated from the body.
• in patients with haemodynamically relevant renal artery stenosis, bilateral or unilateral in the single kidney.
• in patients with hypotensive or haemodynamically unstable states.
• with aliskiren-containing medicines in patients with diabetes or with moderate to severe renal impairment (creatinine clearance <60 ml/min).
• with angiotensin II receptor antagonists (AIIRAs) in patients with diabetic nephropathy.
• during pregnancy.

Concomitant use of ACE inhibitors and extracorporeal treatments leading to contact of blood with negatively charged surfaces must be avoided, since such use may lead to severe anaphylactoid reactions. Such extracorporeal treatments include dialysis or haemofiltration with certain high-fux (e.g. polyacrylonitril) membranes and low-density lipoprotein apheresis with dextran sulfate.

Ramipril should be used with caution in patients with impaired renal function, hyperkalaemia, hypotension, and impaired hepatic function.

Concomitant administration with diuretics may lead to serious hypotension and in addition dangerous hyperkalemia with potassium sparing diuretics. Concomitant therapy with lithium may increase the serum lithium concentration. Reduction in BP may affect the ability to drive and operate machinery and this may be exacerbated by alcohol. NSAIDs may reduce the antihypertensive effect of Ramipril and cause deterioration of renal function.

Ramipril must not be taken during pregnancy. Therefore, pregnancy must be excluded before starting treatment. Pregnancy must be avoided in cases where treatment with ACE inhibitors is indispensable. If the patient intends to become pregnant, treatment with ACE inhibitors must be discontinued, i.e. replaced by another form of treatment. If the patient becomes pregnant during treatment, medication with Ramipril must be replaced as soon as possible by a treatment regimen without ACE inhibitors. Otherwise, there is a risk of harm to the fetus. Ramipril is not recommended during breastfeeding.

Elderly: A reduced initial dose of 1.25 mg Ramipril daily must be considered.

Hepatic impairment: Treatment in these patients must therefore be initiated only under close medical supervision. The maximum permitted daily dose in such cases is 2.5 mg Ramipril.

Renal impairment: With a creatinine clearance between 50 and 20 ml/min per 1.73 m2 body surface area, the initial daily dose is generally 1.25 mg Ramipril. The maximum permitted daily dose, in this case, is 5 mg Ramipril. Patients with incompletely corrected fuid or salt depletion, in patients with severe hypertension, as well as in patients in whom a hypotensive reaction would constitute a particular risk, (e.g., with relevant stenoses of the coronary vessels or those supplying the brain) A reduced initial dose of 1.25 mg Ramipril daily must be considered.

Patients pretreated with a diuretic: Consideration must be given to discontinuing the diuretic for at least 2 to 3 days or- depending on the duration of action of the diuretic- longer before starting treatment with Ramipril, or at least to reducing the diuretic dose. The initial daily dose in patients previously treated with a diuretic is generally 1.25 mg Ramipril.

Sign and symptom: Overdosage may cause excessive peripheral vasodilatation (with marked hypotension, shock), bradycardia, electrolyte disturbances, and renal failure.

Management: Primary detoxifcation by, for example, gastric lavage, administration of adsorbents, sodium sulfate; (if possible during the frst 30 minutes). In the event of hypotension administration of α1-adrenergic agonists (e.g. norepinephrine, dopamine) or angiotensin II (angiotensinamide), which is usually available only in scattered research laboratories, must be considered in addition to volume and salt substitution.

Proton Pump Inhibitor

Omeprazole, a substituted benzimidazole, is an inhibitor of gastric acid secretion. It inhibits gastric acid secretion by blocking hydrogen-potassium-adenosine triphosphatase (H⁺/K⁺ ATPase) enzyme system in the gastric parietal cell. After oral administration, the onset of the antisecretory effect occurs within one hour, with the maximum effect occurring within two hours and inhibition of secretion lasts up to 72 hours. When the drug is discontinued, secretory activity returns gradually, over 3 to 5 days.

Oral-

• Benign gastric and duodenal ulcer: 20 mg once daily for 4 weeks in duodenal ulceration, 8 weeks in gastric ulceration; in severe or recurrent cases, dose to be increased to 40 mg daily; maintenance dose for recurrent duodenal ulcer, 20 mg once daily; in prevention of relapse in duodenal ulcer, 10-20 mg daily.
• NSAID-associated duodenal or gastric ulcer: 20 mg once daily for 4 weeks, continued for further 4 weeks, if not fully healed. 20 mg once daily is used as prophylaxis in patients with a history of NSAID-associated duodenal or gastric ulcers.
• Gastro-esophageal reflux disease: 20 mg once daily for 4 weeks, continued for further 4-8 weeks, if not fully healed; 40 mg once daily has been given for 8 weeks in gastro-esophageal reflux disease, refractory to other treatment; maintenance dose is 20 mg once daily.
• Long-term management of acid reflux disease: 10-20 mg daily.
• Acid-related dyspepsia: 10-20 mg once daily for 2-4 weeks.
• Prophylaxis of acid aspiration: 40 mg on the preceding evening, then 40 mg 2-6 hours before surgery.
• Zollinger-Ellison syndrome: Initially 60 mg once daily; usual range 20-120 mg daily (If daily dose is more than 80 mg, 2 divided dose should be used).
• Helicobacter pylori eradication regimen in peptic ulcer disease: Omeprazole is recommended at a dose of 20 mg twice daily in association with antimicrobial agents as detailed below: Amoxicillin 500 mg and Metronidazole 400 mg both three times a day for one week, or Clarithromycin 250 mg and Metronidazole 400 mg both twice a day for one week, or Amoxicillin 1 g and Clarithromycin 500 mg both twice a day for one week.
• Paeditaric use in severe ulcerating reflux esophagitis (Child>1 year): If body-weight 10-20 kg, 10-20 -mg once daily for 4-12 weeks; if body-weight over 20 kg, 20-40 mg once daily for 4-12 weeks.

IV Injection-

• Prophylaxis of acid aspiration: Omeprazole 40 mg to be given slowly (over a period of 5 minutes) as an intravenous injection, one hour before surgery.
• Duodenal ulcer, gastric ulcer or reflux oesophagitis: In patients with duodenal ulcer, gastric ulcer or reflux oesophagitis where oral medication is inappropriate, Omeprazole IV 40 mg once daily is recommended.
• Zollinger- Ellison syndrome (ZES): In patients with Zollinger-Ellison Syndrome the recommended initial dose of Omeprazole given intravenously is 60 mg daily. Higher daily doses may be required and the dose should be adjusted individually. When doses exceed 60 mg daily, the dose should be divided & given twice daily.

Direction for use of IV Injection: Omeprazole lyophilized powder and water for injection is for intravenous administration only and must not be given by any other route. Omeprazole IV injection should be given as a slow intravenous injection. The solution for IV injection is obtained by adding 10 ml water for injection to the vial containing powder. After reconstitution the injection should be given slowly over a period of at least 2 to 5 minutes at a maximum rate of 4 ml/minute. Use only freshly prepared solution. The solution should be used within 4 hours of reconstitution.

Direction for use of IV Infusion: Omeprazole IV infusion should be given as an intravenous infusion over a period of 20-30 minutes or more. The contents of one vial must be dissolved in 100 ml saline for infusion or 100 ml 5% Dextrose for infusion. The solution should be used within 12 hours when Omeprazole is dissolved in saline and within 6 hours when dissolved in 5% Dextrose. The reconstituted solution should not be mixed or co-administered in the same infusion set with any other drug.

Omeprazole is generally well tolerated. Nausea, abdominal colic, paresthesia, dizziness and headache have been stated to be generally mild and transient and not requiring a reduction in dosage.

Omeprazole is contraindicated in patients with known hypersensitivity to any of the components of the formulation.

When gastric ulcer is suspected, the possibility of gastric malignancy should be excluded before treatment with Omeprazole is instituted, as treatment may alleviate the symptoms and delay diagnosis.

Omeprazole can prolong the elimination of diazepam, warfarin and phenytoin. So, reduction of warfarin or phenytoin dose may be necessary when Omeprazole is added to the treatment. There is no evidence of an interaction of Omeprazole with theophylline, propranolol or antacids.

US FDA pregnancy category of Omeprazole is C. However, results from three prospective epidemiological studies indicate no adverse effects of Omeprazole on pregnancy or on the health of the fetus/newborn child. There is no information available on the passage of Omeprazole into breast milk or its effects on the neonate. Breast-feeding should, therefore, be discontinued, if the use of Omeprazole is considered essential.

Keep in a dry place away from light and heat. Keep out of the reach of children.

H2 receptor antagonist

Ranitidine competitively blocks histamine at H2-receptors of the gastric parietal cells which inhibits gastric acid secretion. It does not affect pepsin secretion, pentagastrin-stimulated intrinsic factor secretion or serum gastrin.

Ranitidine Tablet & Syrup:

Duodenal and gastric ulcer: The usual dosage is 150 mg twice daily taken in the morning and evening or 300 mg as a single daily dose at night for 4 to 8 weeks.

Reflux oesophagitis: 150 mg twice daily or 300 mg at bed time for up to 8 weeks.

Zollinger Ellison syndrome: 150 mg 3 times daily and increased if necessary up to 6 g daily in divided doses. Dosage should be continued as long as clinically indicated.

Episodic dyspepsia: 150 mg twice daily or 300 mg at bed time for up to 6 weeks.

Maintenance: 150 mg at night for preventing recurrences.

Child (peptic ulcer): 2-4 mg/kg twice daily, maximum 300 mg daily.

Ranitidine IV injection & IV Infusion:

Ranitidine injection may be given either as a slow (over a period of at least two minutes) intravenous injection of 50 mg, after dilution to a volume of 20 ml per 50 mg dose, which may be repeated every six to eight hours; or as an intermittent intravenous infusion at a rate of 25 mg per hour for two hours; the infusion may be repeated at six to eight hour intervals; or as an intramuscular injection of 50 mg (2 ml) every six to eight hours. In the prophylaxis of haemorrhage from stress ulceration in seriously ill patients or the prophylaxis of recurrent haemorrhage in patients bleeding from peptic ulceration, parenteral administration may be continued until oral feeding commences.

In the prophylaxis of upper gastrointestinal haemorrhage from stress ulceration in seriously ill patient sapriming dose of 50 mg as low as intravenous injection followed by a continuous intravenous infusion of 0.125-0.250 mg/kg/hour may be preferred. In patients considered to be at risk of developing aspiration syndrome Ranitidine injection 50 mg may be given intramuscularly or by slow intravenous injection 45 to 60 minutes before induction of general anaesthesia.

Children: The recommended oral dose for the treatment of peptic ulcer in children is 2 mg/kg to 4 mg/kg twice daily to a maximum of 300 mg ranitidine per day. Safety and effectiveness of Ranitidine injection have not been established in case of children.

Ranitidine is well tolerated and side effects are usually uncommon. Altered bowel habit, dizziness, rash, tiredness, reversible confusional states, headache, decreased blood counts, muscle or joint pain have rarely been reported.

Patients hypersensitive to Ranitidine

Ranitidine should be given in reduced dosage to patients with impaired renal and hepatic function.

Delayed absorption and increased peak serum concentration with propantheline bromide. Ranitidine minimally inhibits hepatic metabolism of coumarin anticoagulants, theophylline, diazepam and propanolol. May alter absorption of pH-dependent drugs (e.g. ketoconazole, midazolam, glipizide). May reduce bioavailability with antacids.

Pregnancy: Ranitidine crosses the placenta. But there is no evidence of impaired fertility or harm to the foetus due to Ranitidine. Like other drugs, Ranitidine should only be used during pregnancy if considered essential.

Lactation: Ranitidine is excreted in human breast milk. Caution should be exercised when the drug is administered to a nursing mother.

Use in elderly patients: In clinical trial the ulcer healing rates have been found similar in patients age 65 and over with those in younger patients. Additionally, there was no difference in the incidence of adverse effects.

Ranitidine is very specific in action and accordingly no particular problems are expected following overdosage with the drug. Symptomatic and supportive therapy should be given as appropriate. If required, the drug may be removed from the plasma by haemodiaiysis.

Slow IV inj: Ranitidine 50 mg diluted to a concentration ≤2.5 mg/mL (e.g. total of 20 mL) with NaCl 0.9% inj or dextrose 5% or 10%, lactated Ringer's, Na bicarbonate 5% soln.

Intermittent slow IV infusion: Ranitidine 50 mg diluted to a concentration ≤0.5 mg/mL (e.g. total of 100 mL) of dextrose 5% inj or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Continuous IV infusion: Ranitidine 150 mg diluted in 250 mL of dextrose 5% inj or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Patients with Zollinger-Ellison syndrome or other hypersecretory conditions: Ranitidine should be diluted to a concentration ≤2.5 mg/mL with dextrose 5% or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Store in a cool and dry place. protect from light.

Tetracycline group of drugs

Tetracycline has its main mechanism of action on protein synthesis, and an energy-dependent active transport system pumps the drug through the inner cytoplasmic membrane of bacteria. Once inside the bacterial cell, Tetracycline binds specifically to the 30s ribosomes and inhibit bacterial protein synthesis.

Many Gram positive aerobic Cocci are susceptible, but many strains of staphylococci, streptococci and even some pneumococci are resistant to Tetracycline. Thus, tetracycline is not the drug of choice in infections due to gram positive aerobes.

Pseudomonas and many Enterobacteriaceae are resistant. Urinary concentrations are adequate for some community - acquired E. coli and consequently, Tetracycline is still used in uncomplicated initial UTIs. Tetracycline is also active against and is the drug of choice for Brucella species, Calymmatobacterium granulomatis, Vibrio cholerae and V. vulnificus.

Tetracycline is also active against anaerobic species of bacteria and since concentrations of the drug are quite high in the gastrointestinal contents, the enteric flora are usually altered by the drug.

Tetracycline is incompletely absorbed from the gastro-intestinal tract, about 60 to 80% of a dose of tetracycline usually being available. It is widely distributed through the body tissues and fluids.

Tetracycline has a half-life of about 12 hours. It is excreted in the urine and in the faeces.

The usual adult oral dosage of Tetracycline is 1-2 g daily given in 2-4 divided doses. The usual oral dosage of Tetracycline for children older than 8 years of age in 25-50 mg/kg daily given in 2-4 divided doses. Alternatively some clinicians recommended that children should receive 0.6-1.2 g/m2 daily.

Tetracycline should be taken preferably one hour before or 2 hours after meals.

Some specific indications along with some information on dosage is given below:

Acne vulgaris: 250 mg four times daily or 500 mg 12 hourly for 1 week; 125-250 mg for several weeks or months. Duration of therapy is determined by individual progress

Acute staphylococcal infections: 1-2 g daily in divided doses for 10-14 days

Acute streptococcal infections: 1-2 g daily in divided doses for 10 days. Prolonged therapy is needed to avoid risk of rheumatic fever or glomerulonephritis

Amoebiasis: 1 g daily in four divided doses or 500 mg 12 hourly for 7 days. Given in association with amoebicidal agents

Brucellosis: 500 mg four times daily plus 1 g streptomycin twice daily for 1 week ; then 500 mg four times daily (no streptomycin) for 1 week. Prolonged therapy is necessary to avoid relapse

Subacute bacterial endocarditis: 1-2 g daily in divided doses for 6 weeks. Usually given in combination with a bactericidal agent

Syphilis: Total 30-40 g given in divided doses over 10-15 days. Serology and spinal fluid examination should follow the administration of tetracycline

Teeth and bone: Tetracycline can cause depression of bone growth, permanent graybrown discoloration of the teeth and enamel hypoplasia when given during tooth development (i.e. during the later half of pregnancy, during infancy and in childhood).

Hypersensitivity reactions such as anaphylaxis, urticaria and rashes are uncommon. Photosensitivity reactions consisting of a red rash on areas exposed to intense sunlight can occur with Tetracycline.

Gastrointestinal effects: Epigastric distress and nausea are commonly seen after oral administration, and these symptoms are somewhat dose related. Vomiting can occur.

Accentuated prerenal azotemia: Tetracycline appears to aggravate pre-existing renal failure by inhibiting protein synthesis, which increases the azotemia from amino acid metabolism.

Superinfections with oral and anogenital candidiasis are relatively common in patients taking Tetracycline.

Esophageal ulcerations: In most cases, the patients were taking the capsules with little or no fluid before going to bed. To help minimize this, oral doses should be given with adequate amounts of fluid.

Tetracycline Hydrochloride is contraindicated in patients hypersensitive to any of the member of tetracycline groups, since cross-sensitivity may occur Tetracycline Hydrochloride should be avoided in patients with systemic lupus erythematosus. Tetracycline Hydrochloride is considered to be contraindicated in renal impairment, particularly if severe ; if it must be given, doses should be reduced.

Care should be taken if Tetracycline Hydrochloride is given to patients with impaired liver function and high doses should be avoided. Potentiality hepatotoxic drugs (including erythromycin, chloramphenicol, isoniazide and sulphonamides) should not be given concomitantly.

Impaired absorption with antacids containing divalent and trivalent cations (e.g. Al, Ca, Mg), Fe, Zn and Na bicarbonate preparations, kaolin-pectin, bismuth subsalicylate, sucralfate, strontium ranelate, colestipol and colestyramine. May interfere with the bactericidal action of penicillin. May potentiate the effect of anticoagulants. May decrease efficacy of oral contraceptives. Nephrotoxic effects may be exacerbated by diuretics or other nephrotoxic drugs. May increase the hypoglycaemic effect of insulin and sulfonylureas in patients with DM. May increase toxic effects of ergot alkaloids and methotrexate.

Tetracycline should not be used during pregnancy because of the risk of hypertoxicity in the mother as well as the effects on the developing foetus. Use in pregnancy potentially during breast-feeding and in children up to the age of 8, or some authorise say 12 years, may result in impaired bone growth and permanent discoloration of the child's teeth.

Store between 20-25° C.

Ranitidine injection may be given either as a slow (over a period of at least two minutes) intravenous injection of 50 mg, after dilution to a volume of 20 ml per 50 mg dose, which may be repeated every six to eight hours; or as an intermittent intravenous infusion at a rate of 25 mg per hour for two hours; the infusion may be repeated at six to eight hour intervals; or as an intramuscular injection of 50 mg (2 ml) every six to eight hours. In the prophylaxis of haemorrhage from stress ulceration in seriously ill patients or the prophylaxis of recurrent haemorrhage in patients bleeding from peptic ulceration, parenteral administration may be continued until oral feeding commences.

In the prophylaxis of upper gastrointestinal haemorrhage from stress ulceration in seriously ill patient sapriming dose of 50 mg as low as intravenous injection followed by a continuous intravenous infusion of 0.125-0.250 mg/kg/hour may be preferred. In patients considered to be at risk of developing aspiration syndrome Ranitidine injection 50 mg may be given intramuscularly or by slow intravenous injection 45 to 60 minutes before induction of general anaesthesia.

Children: The recommended oral dose for the treatment of peptic ulcer in children is 2 mg/kg to 4 mg/kg twice daily to a maximum of 300 mg ranitidine per day. Safety and effectiveness of Ranitidine injection have not been established in case of children.

Ranitidine is well tolerated and side effects are usually uncommon. Altered bowel habit, dizziness, rash, tiredness, reversible confusional states, headache, decreased blood counts, muscle or joint pain have rarely been reported.

Patients hypersensitive to Ranitidine

Ranitidine should be given in reduced dosage to patients with impaired renal and hepatic function.

Delayed absorption and increased peak serum concentration with propantheline bromide. Ranitidine minimally inhibits hepatic metabolism of coumarin anticoagulants, theophylline, diazepam and propanolol. May alter absorption of pH-dependent drugs (e.g. ketoconazole, midazolam, glipizide). May reduce bioavailability with antacids.

Pregnancy: Ranitidine crosses the placenta. But there is no evidence of impaired fertility or harm to the foetus due to Ranitidine. Like other drugs, Ranitidine should only be used during pregnancy if considered essential.

Lactation: Ranitidine is excreted in human breast milk. Caution should be exercised when the drug is administered to a nursing mother.

Use in elderly patients: In clinical trial the ulcer healing rates have been found similar in patients age 65 and over with those in younger patients. Additionally, there was no difference in the incidence of adverse effects.

Ranitidine is very specific in action and accordingly no particular problems are expected following overdosage with the drug. Symptomatic and supportive therapy should be given as appropriate. If required, the drug may be removed from the plasma by haemodiaiysis.

Slow IV inj: Ranitidine 50 mg diluted to a concentration ≤2.5 mg/mL (e.g. total of 20 mL) with NaCl 0.9% inj or dextrose 5% or 10%, lactated Ringer's, Na bicarbonate 5% soln.

Intermittent slow IV infusion: Ranitidine 50 mg diluted to a concentration ≤0.5 mg/mL (e.g. total of 100 mL) of dextrose 5% inj or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Continuous IV infusion: Ranitidine 150 mg diluted in 250 mL of dextrose 5% inj or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Patients with Zollinger-Ellison syndrome or other hypersecretory conditions: Ranitidine should be diluted to a concentration ≤2.5 mg/mL with dextrose 5% or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Store in a cool and dry place. protect from light.

H2 receptor antagonist

Ranitidine competitively blocks histamine at H2-receptors of the gastric parietal cells which inhibits gastric acid secretion. It does not affect pepsin secretion, pentagastrin-stimulated intrinsic factor secretion or serum gastrin.

Ranitidine Tablet & Syrup:

Duodenal and gastric ulcer: The usual dosage is 150 mg twice daily taken in the morning and evening or 300 mg as a single daily dose at night for 4 to 8 weeks.

Reflux oesophagitis: 150 mg twice daily or 300 mg at bed time for up to 8 weeks.

Zollinger Ellison syndrome: 150 mg 3 times daily and increased if necessary up to 6 g daily in divided doses. Dosage should be continued as long as clinically indicated.

Episodic dyspepsia: 150 mg twice daily or 300 mg at bed time for up to 6 weeks.

Maintenance: 150 mg at night for preventing recurrences.

Child (peptic ulcer): 2-4 mg/kg twice daily, maximum 300 mg daily.
