Iodine compounds (Anti-septic Preparations)

Povidone Iodine is a complex of iodine and an organic polymer, povidone. This polymerization makes Povidone Iodine superior to ordinary elemental iodine. It prolongs the germicidal activity of iodine by liberating elemental iodine slowly. Consequently it has a lower toxicity than elemental iodine. It gives rapid microbicidal activity against both Gram-positive and Gram-negative bacteria, protozoa, viruses and fungi/yeasts. It is also sporicidal. It is the only microbicide with this broad spectrum of activity. It is non-staining, exerts prolong germicidal action and is also active in the presence of soap, blood, serum, pus, mucosal secretions and water.

Cream or ointment:

• For the treatment of infection: Apply once or twice daily or at dressing changes for a maximum of 14 days.
• For the prevention of infection: Apply once or twice a week for as long as necessary. The affected skin should be cleaned and dried and can be covered with a dressing or bandage.

Solution: Apply full strength as often as needed as paint, spray, or wet soak. Maybe bandaged (where necessary).

Gargle & Mouthwash: Adults and children over 6 years of age: Use undiluted or diluted with an equal volume of warm water. Gargle or rinse with up to 10 mL for up to 30 seconds without swallowing. Repeat up to four times daily, for up to 14 consecutive days, or as advised by the Registered Dental Surgeon/Physician.

Surgical Scrub:

• For Preoperative and Postoperative washing by Operating Personnel: Wet hands and forearms with water. Pour about 5 mL of Povidone Iodine Surgical Scrub on the palm of the hand and spread over both hands and forearms. Without adding more water, rub the Scrub thoroughly over all areas for about five minutes. Use a brush if desired. Clean thoroughly under fingernails. Add a little water and develop copious suds. Rinse thoroughly under running water. Complete the wash by scrubbing with another 5 mL of Povidone Iodine Surgical Scrub in the same way.
• For Preoperative use on Patients: After the skin area is shaved, wet it with water. Apply Povidone Iodine Surgical Scrub (1 mL is sufficient to cover an area of 20-30 square inches), develop lather and scrub thoroughly for about five minutes. Rinse off by aid of sterile gauze saturated with water.
• For use in the Physician's Office: Use for washing whenever a germicidal soap is required.

Powder: Apply a light dusting of powder to the affected area. When dry, this forms a protective antiseptic layer over the area treated. Or use as advised by the Registered Physician. There are no special dosage recommendations for children or elderly patients.

Ophthalmic Solution: 1 drop 4 times daily or as required, depending upon the severity of the disease, to be instilled into the conjunctival sac.

Povidone Iodine may cause hypersensitivity reactions and irritation of the skin and mucous membranes. The application of povidone Iodine to severe burns or to large areas otherwise denuded of skin may produce systemic adverse effects such as metabolic acidosis, hypernatraemia, and impairment of renal function. It may interfere with thyroid function tests.

It can cause hypersensitivity reactions. Regular use in patients with thyroid disorders (in particular nodular colloid goitre, endemic goitre and Hashimoto's thyroiditis) or those receiving lithium therapy is to be avoided. In severely burnt patients serum iodide levels should be assessed due to possible hepatic and renal impairment. Povidone Iodine Powder should not be used in serious cavities and in Children under the age of 2 years.

Cream or ointment: In case of deep or puncture wounds or serious burns, consult Registered Physician. If redness, irritation, swelling or pain persists or increases or if infection occurs, discontinue use and consult Registered Physician.

Solution: In preoperative prepping, avoid 'pooling' beneath the patient. Prolonged exposure to wet solution may cause irritation or rarely, severe skin reactions. In case of deep or puncture wounds or serious burns, consult Registered Physician. If redness, irritation, swelling or pain persists or increases or if infection occurs, discontinue use and consult Registered Physician.

Gargle & Mouthwash: Regular use should be avoided as prolonged use may lead to the absorption of a significant amount of iodine. Do not use for more than 14 days. If sores or ulcers in the mouth do not heal within 14 days seek dental or medical advice. It is also not for use in children under 6 years of age. Regular use should be avoided in patients on concurrent lithium therapy.

Surgical Scrub: Special caution is needed when regular applications to broken skin are made to patients with pre-existing renal insufficiency. Regular use should be avoided in patients on concurrent lithium therapy. It can permanently discolor white gold jewellery and it is recommended that this type of jewellery should be removed before using this product.

Powder: Care must be taken when used on known iodine sensitivity, although do not normally react to Povidone-Iodine. Excess powder can be washed off readily with warm water. It should be used directly from the container. Not to be administered internally.

Ophthalmic Solution: Patients, who experience blurred vision after application of the eye drops, should not drive or use machinery until their vision has cleared. Contact lenses should not be worn during the instillation of the drug. After instillation, there should be an interval of at least 30 minutes before reinsertion.

It exhibits interaction with strong alkali, sodium thiosulphate, sodium metabisulphite and thiomersal. Use with concurrent lithium therapy has been shown to exhibithypothyroidic effect.

Povidone Iodine Cream, Solution & Powder are not recommended for use during pregnancy because of the possibility of absorption of sufficient iodine to affect the fetal thyroid. American Academy of Pediatrics considers that the use of Povidone-Iodine is usually compatible with breast feeding. Consult Registered Physician. Regular use of Gargle & Mouthwash and Surgical Scrub should also be avoided in pregnant and lactating women.

There is no experience regarding the safety of the Povidone eye drops in human pregnancy or lactation. Administration during pregnancy and lactation is therefore not recommended, except for compelling reasons.

Store below 25°C. Do not freeze. Store in a cool and dry place, protected from light. Keep out of the reach of children. Do not touch the ophthalmic solution dropper tip to any surface as this may contaminate this preparation. Do not use it after one month of the first opening.

Pioglitazone is indicated as an adjunct to diet and exercise to improve glycaemic control in patients with type II diabetes (NIDDM). Pioglitazone is indicated for monotherapy and also indicated for use in combination with sulphonylurea, Metformin or Insulin when diet and exercise plus the single agent does not result in adequate glycaemic control.

Thiazolidinedione Group

Pioglitazone is a preparation of Pioglitazone which is a member of the newest class of oral antidiabetic agent called thiazolidinediones. It depends on the presence of Insulin for its mechanism of action. Pioglitazone decreases Insulin resistance in the periphery and in the liver, resulting in increased Insulin dependent glucose disposal and decreased hepatic glucose output. It also improves abnormality in lipid metabolism by activating peroxisome proliferator activated receptor gamma (PPAR-γ).

Pioglitazone can be taken once daily without regard to meals. The management of antidiabetic therapy should be individualized. Pioglitazone monotherapy may be initiated at 15 mg or 30 mg once daily dosages in patients not adequately controlled with diet and exercise alone. For patients who respond inadequately to the initial dose of Pioglitazone, the dose can be increased up to 45 mg once daily. For patients not responding adequately to monotherapy, combination therapy should be considered.

Maximum recommended daily dose of Pioglitazone should not exceed 45 mg since doses higher than 45 mg have not been studied in placebo controlled clinical studies. Besides, no placebo controlled clinical studies of more than 30 mg once daily have been conducted in combination therapy.

The overall incidence and types of adverse events reported in placebo controlled clinical trials of Pioglitazone monotherapy at doses of 7.5 mg, 15 mg, 30 mg or 45 mg once daily are upper respiratory tract infection (13.2%), headache (9.1%), sinusitis (6.3%), myalgia (5.4%), tooth disorder (5.3%), and pharyngitis (5.1%).

Pioglitazone is contraindicated in patients with known hypersensitivity to any of its components.

Pioglitazone exerts its antihyperglycaemic effect only in the presence of Insulin. Therefore, it should not be used in Type 1 diabetes or for the treatment of diabetic ketoacidosis. Pioglitazone should be used with caution in case of combination antidiabetic therapy and hepatic insufficiency. Liver enzyme should be monitored regularly.

Administration of thiazolidinediones with an oral contraceptive containing ethinyl oestradiol and norethindrone reduces the plasma concentration of both hormones by approximately 30% which could result in loss of contraception.

Pregnancy: There are no adequate and well controlled studies in pregnant women. Pioglitazone should be used during pregnancy only if the potential benefit justifies the potential risk to the foetus.

Lactation: It is not known whether Pioglitazone is secreted in human milk. As many drugs are excreted in human milk, it should not be administered to a lactating women.

Store at 25° C.

Pioglitazone & Metformin combination is indicated as an adjunct to diet and exercise to improve glycemic control in patients with type 2 diabetes who are already treated with a combination of Pioglitazone and Metformin or whose diabetes is not adequately controlled with Metformin alone or for those patients who have initially responded to Pioglitazone and require additional glycemic control.

Combination Oral hypoglycemic preparations

Pioglitazone depends on the presence of insulin for its mechanism of action. Pioglitazone decreases insulin resistance in the periphery and in the liver resulting in increased insulindependent glucose disposal and decreased hepatic glucose output. Pioglitazone is a potent and highly selective agonist for peroxisome proliferator-activated receptor-gamma (PPARg). Activation of PPARg nuclear receptors modulates the transcription of a number of insulin responsive genes involved in the control of glucose and lipid metabolism.

Metformin hydrochloride improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucose and improves insulin sensitivity by increasing peripheral glucose uptake and utilization. Unlike sulfonylureas, metformin does not produce hypoglycemia in either patients with type 2 diabetes or normal subjects and does not cause hyperinsulinemia.

General: The use of antihyperglycemic therapy in the management of type 2 diabetes should be individualized on the basis of effectiveness and tolerability while not exceeding the maximum recommended daily dose of Pioglitazone 45 mg and Metformin 2550 mg.

Dosage Recommendations: Selecting the starting dose of Pioglitazone & Metformin should be based on the patient's current regimen of Pioglitazone and/or Metformin. Pioglitazone & Metformin should be given in divided daily doses with meals to reduce the gastrointestinal side effects associated with Metformin.

Starting dose for patients inadequately controlled on Metformin monotherapy Based on the usual starting dose of Pioglitazone (15-30 mg daily), Pioglitazone & Metformin may be initiated at either the 15 mg/500 mg or 15 mg/850 mg tablet strength once or twice daily, and gradually titrated after assessing adequacy of therapeutic response. Starting dose for patients who initially responded to Pioglitazone monotherapy and require additional glycemic control

Based on the usual starting doses of Metformin (500 mg twice daily or 850 mg daily), Pioglitazone & Metformin may be initiated at either the 15 mg/500 mg twice daily or 15 mg/850 mg tablet strength once daily, and gradually titrated after assessing adequacy of therapeutic response.

Starting dose for patients switching from combination therapy of Pioglitazone plus Metformin as separate tablets Pioglitazone & Metformin may be initiated with either the 15 mg/500 mg or 15 mg/850 mg tablet strengths based on the dose of Pioglitazone and Metformin already being taken.

Maximum Recommended Dose: Pioglitazone & Metformin tablets are available as a 15 mg Pioglitazone plus 500 mg Metformin or a 15 mg Pioglitazone plus 850 mg Metformin formulation for oral administration. The maximum recommended dose for Pioglitazone is 45 mg daily. The maximum recommended daily dose for Metformin is 2550 mg in adults. Special Patient Populations: The initial and maintenance dosing of combination of Pioglitazone and Metformin should be conservative in patients with advanced age, due to the potential for decreased renal function in this population. Generally, elderly, debilitated, and malnourished patients should not be titrated to the maximum dose of combination of Pioglitazone and Metformin. Monitoring of renal function is necessary to aid in prevention of Metformin associated lactic acidosis, particularly in the elderly. Therapy with combination of Pioglitazone and Metformin should not be initiated if the patient exhibits clinical evidence of active liver disease or increased serumtransaminase levels (ALT greater than 2.5 times the upper limit of normal) at start of therapy. Liver enzyme monitoring is recommended in all patients prior to initiation of therapy with combination of Pioglitazone and Metformin and periodically thereafter

Generally this combined preparation is well tolerated. However, the most common side effects are upper respiratory tract infection, diarrhea, peripheral edema and headache, respectively. These are mild in severity.

Contraindicated in patients with:

• Renal disease or renal dysfunction (e.g. as suggested by serum creatinine levels >1.5 mg/dl in male, >1.4 mg/dl in females or abnormal creatinine clearance), which may also result from conditions such as cardiovascular collapse (shock), acute myocardial infarction and septicemia.
• Known hypersensitivity to Pioglitazone, Metformin or any other component of this combination.
• Acute or chronic metabolic acidosis including diabetic ketoacidosis with or without coma.

Pioglitazone exerts its antihyperglycemic effect only in the presence of insulin. Therefore, Pioglitazone should not be used in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis. Pioglitazone should be used with caution in combination especially with insulin, hepatic insufficiency and heart diseases.

Metformin is known to be substantially excreted by the kidney and the risk of Metformin accumulation and lactic acidosis increases with the degree of impairment of renal function. Thus patients with serum creatinine levels above the upper limit of normal for their age should not receive this combination.

May impair vit B12 absorption. Increased plasma levels with strong CYP2C8 inhibitors (e.g. gemfibrozil). Decreased plasma levels with CYP2C8 inducers (e.g. rifampicin). Reduced metabolism with cationic drugs eliminated by renal tubular secretion.

Pregnancy: There are no adequate and well-controlled studies in pregnant women with this combination or its individual components. So, it should only be used if the potential benefit justifies the potential risk to the fetus.

Nursing mother: It is not known whether Pioglitazone and/or Metformin are secreted in human milk. Because many drugs are excreted in human milk, this combination should not be administered to a breastfeeding woman.

The initial and maintenance dose of Pioglitazone & Metformin should be carefully selected in patients with advanced age due to the potential for decreased renal function in these populations. Monitoring of renal function is necessary to aid in prevention of Metformin associated lactic acidosis, particularly in the elderly. Pioglitazone & Metformin should not be initiated if the patients exhibit clinical evidence of active liver disease. Liver enzyme monitoring is recommended in all patients prior to initiation of therapy with combination of Pioglitazone and Metformin and periodically thereafter.

In the event of Overdosage, appropriate supportive treatment should be initiated according to patient's clinical signs and symptoms.

Store in a cool and dry place. Protect from light and moisture. Keep out of the reach of the children.

Pioglitazone is a potent and highly selective agonist for peroxisome proliferator-activated receptor-gamma (PPARg). Activation of PPARg nuclear receptors modulates the transcription of a number of insulin responsive genes involved in the control of glucose and lipid metabolism.

Metformin hydrochloride improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucose and improves insulin sensitivity by increasing peripheral glucose uptake and utilization. Unlike sulfonylureas, metformin does not produce hypoglycemia in either patients with type 2 diabetes or normal subjects and does not cause hyperinsulinemia.

General: The use of antihyperglycemic therapy in the management of type 2 diabetes should be individualized on the basis of effectiveness and tolerability while not exceeding the maximum recommended daily dose of Pioglitazone 45 mg and Metformin 2550 mg.

Dosage Recommendations: Selecting the starting dose of Pioglitazone & Metformin should be based on the patient's current regimen of Pioglitazone and/or Metformin. Pioglitazone & Metformin should be given in divided daily doses with meals to reduce the gastrointestinal side effects associated with Metformin.

Starting dose for patients inadequately controlled on Metformin monotherapy Based on the usual starting dose of Pioglitazone (15-30 mg daily), Pioglitazone & Metformin may be initiated at either the 15 mg/500 mg or 15 mg/850 mg tablet strength once or twice daily, and gradually titrated after assessing adequacy of therapeutic response. Starting dose for patients who initially responded to Pioglitazone monotherapy and require additional glycemic control

Based on the usual starting doses of Metformin (500 mg twice daily or 850 mg daily), Pioglitazone & Metformin may be initiated at either the 15 mg/500 mg twice daily or 15 mg/850 mg tablet strength once daily, and gradually titrated after assessing adequacy of therapeutic response.

Starting dose for patients switching from combination therapy of Pioglitazone plus Metformin as separate tablets Pioglitazone & Metformin may be initiated with either the 15 mg/500 mg or 15 mg/850 mg tablet strengths based on the dose of Pioglitazone and Metformin already being taken.

Maximum Recommended Dose: Pioglitazone & Metformin tablets are available as a 15 mg Pioglitazone plus 500 mg Metformin or a 15 mg Pioglitazone plus 850 mg Metformin formulation for oral administration. The maximum recommended dose for Pioglitazone is 45 mg daily. The maximum recommended daily dose for Metformin is 2550 mg in adults. Special Patient Populations: The initial and maintenance dosing of combination of Pioglitazone and Metformin should be conservative in patients with advanced age, due to the potential for decreased renal function in this population. Generally, elderly, debilitated, and malnourished patients should not be titrated to the maximum dose of combination of Pioglitazone and Metformin. Monitoring of renal function is necessary to aid in prevention of Metformin associated lactic acidosis, particularly in the elderly. Therapy with combination of Pioglitazone and Metformin should not be initiated if the patient exhibits clinical evidence of active liver disease or increased serumtransaminase levels (ALT greater than 2.5 times the upper limit of normal) at start of therapy. Liver enzyme monitoring is recommended in all patients prior to initiation of therapy with combination of Pioglitazone and Metformin and periodically thereafter

Generally this combined preparation is well tolerated. However, the most common side effects are upper respiratory tract infection, diarrhea, peripheral edema and headache, respectively. These are mild in severity.

Contraindicated in patients with:

• Renal disease or renal dysfunction (e.g. as suggested by serum creatinine levels >1.5 mg/dl in male, >1.4 mg/dl in females or abnormal creatinine clearance), which may also result from conditions such as cardiovascular collapse (shock), acute myocardial infarction and septicemia.
• Known hypersensitivity to Pioglitazone, Metformin or any other component of this combination.
• Acute or chronic metabolic acidosis including diabetic ketoacidosis with or without coma.

Pioglitazone exerts its antihyperglycemic effect only in the presence of insulin. Therefore, Pioglitazone should not be used in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis. Pioglitazone should be used with caution in combination especially with insulin, hepatic insufficiency and heart diseases.

Metformin is known to be substantially excreted by the kidney and the risk of Metformin accumulation and lactic acidosis increases with the degree of impairment of renal function. Thus patients with serum creatinine levels above the upper limit of normal for their age should not receive this combination.

May impair vit B12 absorption. Increased plasma levels with strong CYP2C8 inhibitors (e.g. gemfibrozil). Decreased plasma levels with CYP2C8 inducers (e.g. rifampicin). Reduced metabolism with cationic drugs eliminated by renal tubular secretion.

Pregnancy: There are no adequate and well-controlled studies in pregnant women with this combination or its individual components. So, it should only be used if the potential benefit justifies the potential risk to the fetus.

Nursing mother: It is not known whether Pioglitazone and/or Metformin are secreted in human milk. Because many drugs are excreted in human milk, this combination should not be administered to a breastfeeding woman.

The initial and maintenance dose of Pioglitazone & Metformin should be carefully selected in patients with advanced age due to the potential for decreased renal function in these populations. Monitoring of renal function is necessary to aid in prevention of Metformin associated lactic acidosis, particularly in the elderly. Pioglitazone & Metformin should not be initiated if the patients exhibit clinical evidence of active liver disease. Liver enzyme monitoring is recommended in all patients prior to initiation of therapy with combination of Pioglitazone and Metformin and periodically thereafter.

In the event of Overdosage, appropriate supportive treatment should be initiated according to patient's clinical signs and symptoms.

Store in a cool and dry place. Protect from light and moisture. Keep out of the reach of the children.

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.

Store at 30° or below, protect from light. Keep out of the reach of children. Do not use later than the date of expiry. To be dispensed only on the prescription of a registered physician.

Adjunct anti-epileptic drugs, Drugs used in tremor, tics & related disorder

Piracetam's mechanism of action is not fully understood. The drug influences neuronal and vascular functions and influences cognitive function without acting as a sedative or stimulant. Piracetam is a positive allosteric modulator of the AMPA receptor. It is hypothesized to act on ion channels or ion carriers, thus leading to increased neuron excitability. GABA brain metabolism and GABA receptors are not affected by piracetam

It has been found to increase blood flow and oxygen consumption in parts of the brain, but this may be a side effect of increased brain activity rather than a primary effect or mechanism of action for the drug.

Piracetam improves the function of the neurotransmitter acetylcholine via muscarinic cholinergic (ACh) receptors, which are implicated in memory processes. Furthermore, piracetam may have an effect on NMDA glutamate receptors, which are involved with learning and memory processes. Piracetam is thought to increase cell membrane permeability. Piracetam may exert its global effect on brain neurotransmission via modulation of ion channels (i.e., Na+, K+). It has been found to increase oxygen consumption in the brain, apparently in connection to ATP metabolism, and increases the activity of adenylate kinase in rat brains. Piracetam, while in the brain, appears to increase the synthesis of cytochrome b5, which is a part of the electron transport mechanism in mitochondria. But in the brain, it also increases the permeability of the mitochondria of some intermediaries of the Krebs cycle.

Oral: Adults:

• In cerebro-cortical insufficiency disorders, usual dose is one tablet (800 mg) 3 times a day.
• In myoclonic seizures, a dose of 7.2 gm daily, increasing by 4.8 gm per day every 3 to 4 days up to maximum of 20 gm daily, given in 2 or 3 divided doses.

Oral: Children: The daily dosage depends on the weight of the child, 50 mg/kg of body weight in 3 divided doses. Once the desired results has been obtained, reduce the initial dose by half.

Parenteral formulations: When parenteral administration is needed (e.g. swallowing difficulties, unconsciousness) Piracetam can be administered intravenously. When treating severe symptoms, 12 g daily may need to be administered as an intravenous infusion.

The side effects reported include nervousness, agitation, irritability, anxiety and sleep disturbances. The incidence of these during clinical trials was (≤ 5%) and they were more often noted in the older patients taking > 2.4 gm daily. In the majority of cases, a dose reduction sufficed to make these symptoms disappear. Some patients may complain of fatigue or drowsiness, gastrointestinal problems, e.g. nausea, vomiting, diarrhoea and stomachache have also been reported but their incidence during clinical trials was ≤ 2%. Other symptoms e.g. vertigo, headache, trembling and sexual stimulation have occasionally been reported.

Piracetam is contra-indicated in patients with severe renal insufficiency (creatinine clearance < 20 ml/min) and hepatic impairment. As the principal route of elimination for Piracetam is via the kidney, special care must be taken when treating patients known to suffer from renal insufficiency. Monitoring of renal function is recommended in such cases. The increase in half-life is directly related to the decrease in renal function and creatinine clearance. This is also true for the older patient in whom creatinine clearance is dependent on age. When the creatinine clearance is < 60 ml/min, or serum creatinine is >1.25 mg/100 ml, the dosage prescribed should be calculated as following:

CrCl 60-40 ml/min: Dosage should be 1/2 of normal dose
CrCl 40-20 ml/min: Dosage should be 1/4 of normal dose

In a single case, confusion, irritability and sleep disorders were reported in concomitant use with thyroid extract. At present, no interaction has been observed with the following anti-epileptic drugs, clonazepam, carbamazepine, phenyton, phenobarbitone and sodium valporate, based on a small number of studies.

Piracetam should not be prescribed during pregnancy or when breast feeding, except under exceptional circumstances. Piracetam is able to cross the placenta.

Children: No formal pharmacokinetic study has been conducted in children.

Elderly: In the elderly, the half-life of piracetam is increased and the increase is related to the decrease in renal function in this population (see Section Dosage and Administration).

Renal impairment: Piracetam clearance is correlated to creatinine clearance. It is therefore recommended to adjust the daily dose of piracetam based on creatinine clearance in patients with renal impairment 

Hepatic impairment: The influence of hepatic impairment on the pharmacokinetics of piracetam has not been evaluated. Because 80 to 100% of the dose is excreted in the urine as unchanged drug, hepatic impairment solely would not be expected to have a significant effect on piracetam elimination.

Piracetam appears to be devoid of toxicity even at very high doses and, therefore, the need for specific measures to be taken in case of an overdose is avoided. Drug Interactions: In a single case, confusion, irritability and sleep disorders were reported in concomitant use with thyroid extract. At present, no interaction has been observed with the following anti-epileptic drugs, clonazepam, carbamazepine, phenytoin, phenobarbitone and sodium valproate, based on a small number of studies.

Piracetam is compatible (physico-chemical compatibility) with the perfusions of:

• Glucose 5%, 10%, 20%
• Fructose 5%, 10%, 20%
• Sodium chloride 0.9%
• Dextran 40 (10% in a 0.9% NaCl solution)
• Ringer Mannitol 20%
• HES solution (Hydroxy Ethyl Starch) 6% and 10%

The stability of these solutions has been demonstrated up to 24 hours.

Treatment of novel or re-emerging pandemic influenza virus infections (limited to cases in which other influenza antiviral drugs are ineffective or not sufficiently effective).

Anti-viral drugs

Favipiravir is a new antiviral drug against influenza. It is metabolized into favipiravir ribosyl triphosphate (favipiravir RTP) by an intracellular enzyme, and favipiravir RTP selectively inhibits RNA polymerase (RNA-dependent RNA polymerase) of the influenza virus, preventing replication of the influenza virus. It is a drug with a mechanism of action different from that of the existing influenza antiviral drugs and effective against all types and sub-types of human influenza A, B, and C viruses in vitro, showing a wide range of anti-viral activity against various influenza virus strains including avian and swine viruses.

The usual adult dosage is 1600 mg of Favipiravir administered orally twice daily on Day 1, followed by 600 mg orally twice daily from Day 2 to Day 5 or as directed by physicians. The total treatment duration should be 5 days.

Most common side effects are Diarrhea and increase of blood uric acid levels.

Favipiravir is contraindicated for pregnant women and women who may possibly be pregnant.

Favipiravir should not be given in pregnant women, requirement of the confirmation of non-pregnancy in women of childbearing potential before use, thorough contraception measures from the start of the treatment to 7 days after the end of the treatment. Caution should be taken for Hepatic and renal impaired patient or use Favipiravir as per the direction of registered Physician

In animal studies, decreased RBC production,and increases in liver function parameters such as AST, ALP, ALT and total bilirubin, and increased vacuolization in hepatocytes. Toxicity information regarding Favipiravir in humans is not readily available.

Favipiravir may cause delayed development or death of embryos during the early stage of pregnancy. Should not be given during pregnancy.

This drug is only approved as an experimental drug and still a lot of studies is needed about it’s efficacy and also toxic reactions and use in children.

In animal studies, decreased RBC production,and increases in liver function parameters such as AST, ALP, ALT and total bilirubin, and increased vacuolization in hepatocytes. Toxicity information regarding Favipiravir in humans is not readily available.

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

It is a drug with a mechanism of action different from that of the existing influenza antiviral drugs and effective against all types and sub-types of human influenza A, B, and C viruses in vitro, showing a wide range of anti-viral activity against various influenza virus strains including avian and swine viruses.

The usual adult dosage is 1600 mg of Favipiravir administered orally twice daily on Day 1, followed by 600 mg orally twice daily from Day 2 to Day 5 or as directed by physicians. The total treatment duration should be 5 days.

Most common side effects are Diarrhea and increase of blood uric acid levels.

Favipiravir is contraindicated for pregnant women and women who may possibly be pregnant.

Favipiravir should not be given in pregnant women, requirement of the confirmation of non-pregnancy in women of childbearing potential before use, thorough contraception measures from the start of the treatment to 7 days after the end of the treatment. Caution should be taken for Hepatic and renal impaired patient or use Favipiravir as per the direction of registered Physician

Favipiravir may cause delayed development or death of embryos during the early stage of pregnancy. Should not be given during pregnancy.

This drug is only approved as an experimental drug and still a lot of studies is needed about it’s efficacy and also toxic reactions and use in children.

In animal studies, decreased RBC production,and increases in liver function parameters such as AST, ALP, ALT and total bilirubin, and increased vacuolization in hepatocytes. Toxicity information regarding Favipiravir in humans is not readily available.

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

This syrup is indicated as an antitussive, for the relief of persistent, dry, irritating cough and aids restful sleep.

Combined cough expectorants, Combined cough suppressants

Dextromethorphan Hydrobromide is a non-opioid antitussive drug. It exerts its antitussive activity by acting on the cough center in the medulla oblongata, raising the threshold for the cough reflex. Levomenthol has mild local anesthetic and decongestant properties. Diphenhydramine Hydrochloride possesses antitussive, antihistaminic, anticholinergic properties.

Adults and children over 12 years: 2 teaspoonfuls of syrup 4 times a day or as directed by the physicians. Do not take more than 8 teaspoonfuls of syrup in 24 hours.

Use in children & Adolescents: The efficacy and safely of Dextromethorphan Hydrobromide have not been established in pediatric patients and adolescents.

This syrup may cause drowsiness, dizziness, nausea, vomiting, gastrointestinal disturbance, dry mouth, nose and throat difficulty in urination, or blurred vision.

This syrup is contraindicated in individuals with known hypersensitivity to the product or any of its components. This medicine is contraindicated in individuals who are taking, or have taken, monoamine oxidase inhibitor within the preceding two weeks. Dextromethorphan, In common with other centrally acting antitussive agents, should not be given to subjects in, or at risk of developing respiratory failure.

This syrup may cause drowsiness; if affected, individuals should not drive or operate machinery. Diphenhydramine Hydrochloride should not be taken by individuals with narrow-angle glaucoma or symptomatic prostatic hypertrophy. Caution is particularly recommended for adolescents and young adults as well as in patients with a history of drug abuse or psychoactive substances.

This syrup contains Diphenhydramine Hydrochloride and therefore may potentiate the effects of alcohol, and other CNS depressants. As Diphenhydramine Hydrochloride possess some anticholinergic activity, the effects of anticholinergics (e.g. some psychotrophic drugs and atropine) may be potentiated by this product. This may result in tachycardia, mouth dryness, gastrointestinal disturbances (e.g. colic), urinary retention and headache. The concomitant use of a Dextromethorphan Hydrobromide containing product and monoamine oxidase inhibitors can occasionally result in symptoms such as hyperpyrexia, hallucinations, gross excitation or coma.

Pregnancy: Both Diphenhydramine Hydrochloride and Dextromethorphan Hydrobromide have been in widespread use for many years without apparent ill consequences. However, there is insufficient information on the effects of the administration of Dextromethorphan Hydrobromide during human pregnancy.

Lactation: It is not known whether dextromethorphan or its metabolites are excreted in breast milk. Diphenhydramine Hydrochloride is known to cross the placenta and has also been detected in breast milk. The syrup should therefore only be used when the potential benefit of treatment to the mother exceeds any possible hazards to the developing fetus or suckling infant.

With higher doses, and particularly in children, hallucinations and convulsions may appear; with massive doses, coma or cardiovascular collapse may follow. Treatment of overdose should be symptomatic and supportive. Measures to promote rapid gastric emptying and in cases of acute poisoning the use of activated charcoal may be useful. Naloxone has been used successfully as a specific antagonist to dextromethorphan toxicity in children. Convulsions may be controlled with diazepam and thiopental sodium.

Store at a temperature not exceeding 30°C in a dry place. Protect from liqht & moisture. Keep out of the reach of children.

Pirfenidone is indicated in adults for the treatment of mild to moderate Idiopathic Pulmonary Fibrosis (IPF).

Immunosuppressant

Pirfenidone is an orally active, small molecule that shows a wide range of biologic activity. In vitro evidence has shown that pirfenidone inhibits collagen synthesis, down-regulates profibrotic cytokines and decreases fibroblast proliferation. Pirfenidone leads to a reduction of TGF-beta2 mRNA levels and of the mature TGF-beta2 protein due to decreased expression and direct inhibition of the TGF-beta pro-protein convertase furin. In addition, pirfenidone reduces the protein levels of the matrix metalloproteinase (MMP)-11, a TGF-beta target gene and furin substrate involved in carcinogenesis.

Treatment with Pirfenidone should be initiated and supervised by specialist physicians experienced in the diagnosis and treatment of IPF. Upon initiating treatment, the dose should be titrated to the recommended daily dose of nine 267 mg tablets or one 801 mg tablet per day over a 14-days period for adult as follows:

• Days 1 to 7: One 267 mg tablet administered three times a day (801 mg/day)
• Days 8 to 14: One 534 mg tablets administered three times a day (1602 mg/day)
• Day 15 onward: Three 267 mg tablets or one 801 mg tablet administered three times a day (2403 mg/day)

The recommended daily dose of Pirfenidone for patients with IPF is three 267 mg tablets or one 801 mg three times a day with food for a total of 2403 mg/day. Doses above 2403 mg/day are not recommended for any patient. Patients who miss 14 consecutive days or more of Pirfenidone treatment should re-initiate therapy by undergoing the initial 2-week titration regimen up to the recommended daily dose. For treatment interruption of less than 14 consecutive days, the dose can be resumed at the previous recommended daily dose without titration.

Dose adjustments and other considerations for safe use: Gastrointestinal events: In patients who experience intolerance to therapy due to gastrointestinal side effects, patients should be reminded to take the medicinal product with food. If symptoms persist Pirfenidone may be reduced to 1-2 capsules (267 mg-534 mg) 2-3 times/day with food with re-escalation to the recommended daily dose as tolerated. If symptoms continue, patients may be instructed to interrupt treatment for 1 to 2 weeks to allow symptoms to resolve.

Photosensitivity reaction or rash: Patients who experience a mild to moderate photosensitivity reaction or rash should be reminded of the instruction to use a sunblock daily and to avoid sun exposure. The dose of Pirfenidone may be reduced to 3 capsules/day (1 capsule three times a day). If the rash persists after 7 days, Pirfenidone should be discontinued for 15 days, with re-escalation to the recommended daily dose in the same manner as the dose escalation period. Patients who experience severe photosensitivity reaction or rash should be instructed to interrupt the dose and to seek medical advice. Once the rash has resolved, Pirfenidone may be re-introduced and re-escalated up to the recommended daily dose at the discretion of the physician.

Hepatic function: In the event of significant elevation of alanine and/or aspartate aminotransferases (ALT/AST) with or without bilirubin elevation, the dose of Pirfenidone should be adjusted or treatment discontinued according to the guidelines.

The safety of Pirfenidone has been evaluated in clinical studies including 1345 healthy volunteers and patients. The most commonly reported (10%) adverse reactions during clinical study experience with Pirfenidone at a dose of 2403 mg/day compared to placebo, respectively, were nausea (32.8% versus 13.3%), rash (28.7% versus 8.6%), fatigue (22.3% versus 13.3%), diarrhoea (21.7% versus 13.5%), dyspepsia (16.8% versus 5.5%), and photosensitivity reaction (12.2% versus 1.7%). Serious adverse reactions were recorded at similar frequencies among patients treated with 2403 mg/day of Pirfenidone and placebo in clinical studies. The adverse reactions reported at a frequency of 2% in 345 patients receiving Pirfenidone at the recommended dose of 2403 mg/day in two pivotal Phase 3 studies. Adverse reactions from post-marketing experience are also listed. Adverse reactions are listed by System Organ Class (SOC) and within each frequency grouping the adverse reactions are presented in order of decreasing seriousness.

Hypersensitivity to the active substance or to any of the excipients, concomitant use of fluvoxamine, severe hepatic impairment or end stage liver disease, severe renal impairment (CrCl <30 ml/min) or end stage renal disease requiring dialysis.

Hepatic function: Elevations in ALT and AST >3 × upper limit of normal (ULN) have been reported in patients receiving therapy with Pirfenidone. Rarely these have been associated with concomitant elevations in total serum bilirubin. Liver function tests (ALT, AST and bilirubin) should be conducted prior to the initiation of treatment with Pirfenidone, and subsequently at monthly intervals for the first 6 months and then every 3 months thereafter. In the event of significant elevation of liver aminotransferases the dose of Pirfenidone should be adjusted or treatment discontinued according to the guidelines listed below. For patients with confirmed elevations in ALT, AST or bilirubin during treatment, the following dose adjustments may be necessary.

Recommendations in case of ALT/AST elevations: If a patient exhibits an aminotransferase elevation to >3 to ≤5 X ULN after starting Pirfenidone therapy, confounding medicinal products should be discontinued, other causes excluded, and the patient monitored closely. If clinically appropriate the dose of Pirfenidone should be reduced or interrupted. Once liver function tests are within normal limits Pirfenidone may be re-escalated to the recommended daily dose if tolerated. If a patient exhibits an aminotransferase elevation to >5 X ULN accompanied by symptoms or hyperbilirubinaemia, Pirfenidone should be discontinued and the patient should not be rechallenged. If a patient exhibits an aminotransferase elevation to >5 X ULN, Pirfenidone should be discontinued and the patient should not be rechallenged.

Hepatic impairment: In subjects with moderate hepatic impairment (i.e. Child-Pugh Class B), Pirfenidone exposure was increased by 60%. Pirfenidone should be used with caution in patients with pre-existing mild to moderate hepatic impairment (i.e. Child-Pugh Class A and B) given the potential for increased Pirfenidone exposure. Patients should be monitored closely for signs of toxicity especially if they are concomitantly taking a known CYP1A2 inhibitor. Pirfenidone has not been studied in individuals with severe hepatic impairment and Pirfenidone should not be used in patients with severe hepatic impairment.

Photosensitivity reaction and rash: Exposure to direct sunlight (including sunlamps) should be avoided or minimised during treatment with Pirfenidone. Patients should be instructed to use a sunblock daily, to wear clothing that protects against sun exposure, and to avoid other medicinal products known to cause photosensitivity. Patients should be instructed to report symptoms of photosensitivity reaction or rash to their physician. Severe photosensitivity reactions are uncommon. Dose adjustments or temporary treatment discontinuation may be necessary in mild to severe cases of photosensitivity reaction or rash.

Dizziness: Dizziness has been reported in patients taking Pirfenidone. Therefore, patients should know how they react to this medicinal product before they engage in activities requiring mental alertness or coordination. In clinical studies, most patients who experienced dizziness had a single event, and most events resolved, with a median duration of 22 days. If dizziness does not improve or if it worsens in severity, dose adjustment or even discontinuation of Pirfenidone may be warranted.

Fatigue: Fatigue has been reported in patients taking Pirfenidone. Therefore, patients should know how they react to this medicinal product before they engage in activities requiring mental alertness or coordination.

Weight loss: Weight loss has been reported in patients treated with Pirfenidone. Physicians should monitor patients’ weight, and when appropriate encourage increased caloric intake if weight loss is considered to be of clinical significance. Interactions with other medicinal products and other forms of interaction. Approximately 70-80% of pirfenidone is metabolised via CYP1A2 with minor contributions from other CYP isoenzymes including CYP2C9, 2C19, 2D6 and 2E1. Consumption of grapefruit juice is associated with inhibition of CYP1A2 and should be avoided during treatment with pirfenidone.

Fluvoxamine and inhibitors of CYP1A2: In a Phase 1 study, the co-administration of Pirfenidone and fluvoxamine (a strong inhibitor of CYP1A2 with inhibitory effects on other CYP isoenzymes [CYP2C9, 2C19, and 2D6]) resulted in a 4-fold increase in exposure to pirfenidone in non-smokers. Pirfenidone is contraindicated in patients with concomitant use of fluvoxamine. Fluvoxamine should be discontinued prior to the initiation of Pirfenidone therapy and avoided during Pirfenidone therapy due to the reduced clearance of pirfenidone. Other therapies that are inhibitors of both CYP1A2 and one or more other CYP isoenzymes involved in the metabolism of pirfenidone (e.g. CYP2C9, 2C19, and 2D6) should be avoided during pirfenidone treatment. In vitro in vivo extrapolations indicate that strong and selective inhibitors of CYP1A2 (e.g. enoxacin) have the potential to increase the exposure to pirfenidone by approximately 2 to 4-fold. If concomitant use of Pirfenidone with a strong and selective inhibitor of CYP1A2 cannot be avoided, the dose of Pirfenidone should be reduced to 801 mg daily (one capsule, three times a day). Patients should be closely monitored for emergence of adverse reactions associated with Pirfenidone therapy. Discontinue Pirfenidone if necessary.

Co-administration of Pirfenidone and 750 mg of ciprofloxacin (a moderate inhibitor of CYP1A2) increased the exposure to pirfenidone by 81%. If ciprofloxacin at the dose of 750 mg twice daily cannot be avoided, the dose of Pirfenidone should be reduced to 1602 mg daily (two capsules, three times a day). Pirfenidone should be used with caution when ciprofloxacin is used at a dose of 250 mg or 500 mg once or twice daily. Pirfenidone should be used with caution in patients treated with other moderate inhibitors of CYP1A2 (e.g. amiodarone, propafenone). Special care should also be exercised if CYP1A2 inhibitors are being used concomitantly with potent inhibitors of one or more other CYP isoenzymes involved in the metabolism of pirfenidone such as CYP2C9 (e.g. amiodarone, fluconazole), 2C19 (e.g. chloramphenicol) and 2D6 (e.g. fluoxetine, paroxetine).

Cigarette smoking and inducers of CYP1A2: A Phase 1 interaction study evaluated the effect of cigarette smoking (CYP1A2 inducer) on the pharmacokinetics of Pirfenidone. The exposure to pirfenidone in smokers was 50% of that observed in non-smokers. Smoking has the potential to induce hepatic enzyme production and thus increase medicinal product clearance and decrease exposure. Concomitant use of strong inducers of CYP1A2 including smoking should be avoided during Pirfenidone therapy based on the observed relationship between cigarette smoking and its potential to induce CYP1A2. Patients should be encouraged to discontinue use of strong inducers of CYP1A2 and to stop smoking before and during treatment with pirfenidone. In the case of moderate inducers of CYP1A2 (e.g. omeprazole), concomitant use may theoretically result in a lowering of pirfenidone plasma levels. Co-administration of medicinal products that act as potent inducers of both CYP1A2 and the other CYP isoenzymes involved in the metabolism of pirfenidone (e.g. rifampicin) may result in significant lowering of pirfenidone plasma levels. These medicinal products should be avoided whenever possible.

Pregnancy: There are no data from the use of Pirfenidone in pregnant women. In animals placental transfer of pirfenidone and/or its metabolites occurs with the potential for accumulation of pirfenidone and/or its metabolites in amniotic fluid. At high doses (1000 mg/kg/day) rats exhibited prolongation of gestation and reduction in fetal viability. As a precautionary measure, it is preferable to avoid the use of Pirfenidone during pregnancy.

Lactation: It is unknown whether pirfenidone or its metabolites are excreted in human milk. Available pharmacokinetic data in animals have shown excretion of pirfenidone and/or its metabolites in milk with the potential for accumulation of pirfenidone and/or its metabolites in milk. A risk to the suckling child cannot be excluded. A decision must be made whether to discontinue breast-feeding or to discontinue from Pirfenidone therapy, taking into account the benefit of breast-feeding for the child and the benefit of Pirfenidone therapy for the mother.

Fertility: No adverse effects on fertility were observed in preclinical studies. Effects on ability to drive and use machines: No studies on the effects of the ability to drive and use machines have been performed. Pirfenidone may cause dizziness and fatigue, which could influence the ability to drive or use machines.

There is limited clinical experience with overdose. Multiple doses of pirfenidone up to a dose of 4806 mg/day were administered as six 267 mg capsules three times daily to healthy adult volunteers over a 12-day dose escalation period. Adverse reactions were mild, transient, and consistent with the most frequently reported adverse reactions for pirfenidone.

Store in a cool and dry place, protected from light.

• Motion sickness and
• Other allergic conditions.

Sedating Anti-histamine

Chlorpheniramine Maleate is an alkylamine antihistamine. It is one of the most potent histamine H1-receptor blocking agents which is used as a potent antihistamine. This generally causes less sedation than promethazine. Chlorpheniramine Maleate exerts its effects by blocking H1-receptor competitively.

Adult- Usual adult dose is 4 mg every 4-6 hours, maximum 24 mg daily.

Child-

• 6-12 years: 2 mg every 4-6 hours, maximum 12 mg daily.
• 2-5 years: 1 mg every 4-6 hours, maximum 6 mg daily.
• 1-2 years: 1 mg twice daily.

Below 1 year the use of Chlorpheniramine Maleate is not recommended.

Chlorpheniramine is well-tolerated, but sometimes drowsiness, dizziness, muscular weakness, and gastrointestinal upset may occur.

Chlorpheniramine is contraindicated in patients hypersensitive to this agent, in newborn or premature infants.

Chlorpheniramine should be used with caution in patients with glaucoma and prostatic hypertrophy. During therapy with chlorpheniramine, caution should be taken in driving vehicles and operating machinery.

Chlorphenamine maleate has been reported to be incompatible with calcium chloride, kanamycin sulfate, noradrenaline acid tartrate, pentobarbital sodium, and meglumine adipiodone.

This drug should not be used in lactating mother and in pregnancy especially during the first trimester of pregnancy.

CNS depression (including sedation, apnea, CV collapse), CNS stimulation (including insomnia, hallucination, tremors, convulsions), tinnitus, blurred vision, dizziness, ataxia, hypotension. Stimulation and atropine-like signs and symptoms (including dry mouth, fixed dilated pupils, flushing, hyperthermia, Gl symptoms) are more likely in children.

Mupirocin ointment is indicated for the topical treatment of impetigo (skin diseases) due to Staphylococcus aureus and Streptococcus pyogenes. It is also indicated in folliculitis, furunculosis.

Topical Antibiotic preparations

Mupirocin is a naturally occurring antibiotic. This antibacterial agent is produced by fermentation using the organism Pseudomonas fluorescens. It is active against a wide range of bacteria (e.g. Staphylococcus aureus including methicillin-resistant strains and Streptococcus pyogenes) those responsible for the majority of skin infections. It is also active against gram-negative pathogens, such as Escherichia coli and Haemophilus influenzae. Mupirocin inhibits bacterial protein synthesis by reversibly and specifically binding to bacterial isoleucyl transfer-RNA synthetase.

A small amount of Bactropen ointment should be applied to the affected area 3 times daily for up to 10 days. The safety and effectiveness of Mupirocin ointment have been established in the age range of 2 months to 16 years.

Reported side effects are burning, stinging or pain, itching and some patient may be suffered rash, nausea, erythema, dry skin, tenderness, swelling, contact dermatitis and increased exudate.

The drug is contraindicated in individuals with a history of hypersensitivity reactions to Mupirocin or any of the components of the preparation.

Mupirocin ointment is not for ophthalmic or intra-nasal use. As with other antibacterial products, prolonged use may result in overgrowth of non-susceptible organisms, including fungi. When Mupirocin is used on the face care should be taken to avoid the eyes. This is not suitable in conjunction with cannulae and at the site of central venous cannulation. In the event of a sensitization or severe local irritation from Mupirocin ointment, usage should be discontinued and appropriate alternative therapy for the infection instituted. Mixing of Mupirocin ointment with other preparations causes risk of dilution, resulting in a reduction of the antibacterial activity and potential loss of stability of the Mupirocin in the ointment.

No drug interaction has been identified with Mupirocin ointment.

Reproduction studies on Mupirocin ointment in animals have revealed no evidence of harm to the foetus. As there is no clinical experience on it’s use during pregnancy, Mupirocin ointment should only be used in pregnancy when the potential benefits outweigh the possible risks of treatment.

It is unknown whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Mupirocin ointment is administered to a nursing woman.

There is currently limited data with overdose of Mupirocin ointment. In the event of overdose, the patient should be treated supportively with appropriate monitoring as necessary.

Keep below 25° C temperature, protected from light and moisture. Do not keep in freeze. Keep out of the reach of children.
