Dipeptidyl Peptidase-4 (DPP-4) inhibitor

Sitagliptin is a DPP-4 inhibitor, which is believed to exert its actions in patients with type 2 diabetes by slowing the inactivation of incretin hormones. Concentrations of the active intact hormones are increased by Sitagliptin, thereby increasing and prolonging the action of these hormones. Incretin hormones, including glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), are released by the intestine throughout the day, and levels are increased in response to a meal. These hormones are rapidly inactivated by the enzyme, DPP-4. The incretins are part of an endogenous system involved in the physiologic regulation of glucose homeostasis. When blood glucose concentrations are normal or elevated, GLP-1 and GIP increase insulin synthesis and release from pancreatic beta cells by intracellular signaling pathways involving cyclic AMP. GLP-1 also lowers glucagon secretion from pancreatic alpha cells, leading to reduced hepatic glucose production. By increasing and prolonging active incretin levels, Sitagliptin increases insulin release and decreases glucagon levels in the circulation in a glucose-dependent manner. Sitagliptin demonstrates selectivity for DPP-4 and does not inhibit DPP-8 or DPP-9 activity in vitro at concentrations approximating those from therapeutic doses.

The recommended dose of sitagliptin is 50 mg twice a day and 100 mg once daily. Sitagliptin can be taken with or without food.

The most common adverse reactions include headache, upper respiratory tract infection and nasopharyngitis. Hypoglycemia may occur in patients treated with the combination to Sitagliptin and sulfonylurea and add on to insulin.

History of a serious hypersensitivity reaction to sitagliptin, such as anaphylaxis or angioedema.

If pancreatitis is suspected, sitagliptin should promptly be discontinued and appropriate management should be initiated.

Use in Patients with Renal Insufficiency: Dosage adjustment is recommended in patients with moderate or severe renal insufficiency and in patients with ESRD requiring hemodialysis or peritoneal dialysis.

Use with medications known to cause Hypoglycemia: When sitagliptin is used in combination therapy dosage adjustment of sulfonylurea or insulin may be required to reduce the risk of hypoglycemia.

Hypersensitivity Reactions: There have been post-marketing reports of serious hypersensitivity reactions in patients treated with sitagliptin. These reactions include anaphylaxis, angioedema, and exfoliative skin conditions including Stevens-Johnson syndrome. If a hypersensitivity reaction is suspected, discontinue sitagliptin, assess for other potential causes for the event, and institute alternative treatment for diabetes.

Effects of sitagliptin on other Drugs: Sitagliptin did not meaningfully alter the pharmacokinetics of metformin, glyburide, simvastatin, rosiglitazone, warfarin, or oral contraceptive.

Digoxin: Sitagliptin slightly increases the mean of Digoxin concentration. However, no dose adjustment of either drug is required.

Pregnancy Category B. Reproduction studies have been performed in rats and rabbits. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Sitagliptin is secreted in the milk of lactating rats at milk to plasma ratio of 4:1. It is not known whether sitagliptin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when sitagliptin is administered to a nursing woman.

Pediatric Use: Safety and effectiveness of sitagliptin in pediatric patients under 18 years of age have not been established.

Geriatric Use: This drug is known to be substantially excreted by the kidney. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection in the elderly, and it may be useful to assess renal function in these patients prior to initiating dosing and periodically thereafter.

For patients with mild renal insufciency: (CrCl <50 ml/min or serum creatinine levels of <1.7 mg/DL in men and <1.5 mg/DL in women), no dosage adjustment for sitagliptin is required.

For patients with moderate renal insufciency: (CrCl <30 to <50 mL/min, or serum creatinine levels of >1.7 to <3.0 mg/dL in men and >1.5 to <2.5 mg/dL in women), the dose of sitagliptin is 50 mg once daily.

For patients with severe renal insufficiency: (CrCl <30 mL/min or serum creatinine levels of >3.0 mg/dL in men and 2.5 mg/dL in women) or with end-stage renal disease (ESRD) requiring hemodialysis or peritoneal dialysis, the dose of sitagliptin is 25 mg once daily. Sitagliptin may be administered without regard to the limiting of hemodialysis.

During controlled clinical trials in healthy subjects, single doses of up to 800 mg Sitagliptin were administered. Maximal mean increases in QTc of 8.0 msec were observed in one study at a dose of 800 mg Sitagliptin, a mean effect that is not considered clinically important. There is no experience with doses above 800 mg in clinical studies. In Phase I multiple-dose studies, there were no dose-related clinical adverse reactions observed with Sitagliptin with doses of up to 600 mg per day for periods of up to 10 days and 400 mg per day for up to 28 days.

In the event of an overdose, it is reasonable to employ the usual supportive measures, e.g., remove unabsorbed material from the gastrointestinal tract, employ clinical monitoring (including obtaining an electrocardiogram), and institute supportive therapy as dictated by the patient's clinical status. Sitagliptin is modestly dialyzable. In clinical studies, approximately 13.5% of the dose was removed over a 3- to 4-hour hemodialysis session. Prolonged hemodialysis may be considered if clinically appropriate. It is not known if sitagliptin is dialyzable by peritoneal dialysis.

Store below 25°C in a dry place away from light. Keep the medicines in a safe place, 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

Combination Oral hypoglycemic preparations

This tablet combines two antihyperglycemic agents with complementary mechanisms of action to improve glycemic control in patients with type 2 diabetes. Sitagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, and Metformin HCl, a member of the biguanide class. Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor, which is believed to exert its actions in patients with type 2 diabetes by slowing the inactivation of incretin hormones. Incretin hormones, including glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), are released by the intestine throughout the day, and levels are increased in response to a meal. These hormones are rapidly inactivated by the enzyme, DPP-4. The incretins are part of an endogenous system involved in the physiologic regulation of glucose homeostasis. When blood glucose concentrations are normal or elevated then GLP-1 and GIP increase insulin synthesis and release from pancreatic beta cells by intracellular signaling pathways involving cyclic AMP. GLP-1 also lowers glucagon secretion from pancreatic alpha cells, leading to reduced hepatic glucose production. By increasing and prolonging active incretin levels, Sitagliptin increases insulin release and decreases glucagon levels in the circulation in a glucose-dependent manner. The pharmacologic mechanism of action of Metformin HCl is different from other classes of oral antihyperglycemic agents. Metformin HCl decreases hepatic glucose production, decreases intestinal absorption of glucose and increases peripheral glucose uptake and utilization.

Dose of film-coated tablet: The dosage of this tablet should be individualized on the basis of the patient's current regimen, efectiveness, and tolerability while not exceeding the maximum recommended daily dose of 100 mg sitagliptin and 2000 mg metformin. Initial combination therapy or maintenance of combination therapy should be individualized and left to the discretion of the health care provider.

This tablet should generally be given twice daily with meals, with gradual dose escalation, to reduce the gastrointestinal (GI) side efects due to metformin.

The starting dose of this tablet should be based on the patient’s current regimen. This tablet should be given twice daily with meals.

The recommended starting dose in patients not currently treated with metformin is 50 mg sitagliptin/500 mg metformin hydrochloride twice daily, with gradual dose escalation recommended to reduce gastrointestinal side efects associated with metformin.

The starting dose in patients already treated with metformin should provide sitagliptin dosed as 50 mg twice daily (100 mg total daily dose) and the dose of metformin already being taken. For patients taking metformin 850 mg twice daily, the recommended starting dose of this tablet is 50 mg sitagliptin/1000 mg metformin hydrochloride twice daily.

No studies have been performed specifcally examining the safety and efcacy of Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP in patients previously treated with other oral antihyperglycemic agents and switched to Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP. Any change in therapy of type 2 diabetes should be undertaken with care and appropriate monitoring as changes in glycemic control can occur.

Dose of extended-release tablet: Administer once daily with a meal preferably in the evening. Gradually escalate the dose to reduce the gastrointestinal side effects due to Metformin. May adjust the dosing based on effectiveness and tolerability while not exceeding the maximum recommended daily dose of 100 mg Sitagliptin and 2000 mg Metformin extended-release. Maintain the same total daily dose of Sitagliptin and Metformin when changing between film-coated tablet and extended-release tablet, without exceeding the maximum recommended daily dose of 2000 mg Metformin extended-release.

Patients using two extended-release tablets (such as two 50/500 or two 50/1000 tablets) should take the two tablets together once daily. The 100 mg Sitagliptin/1000 mg Metformin HCI extended-release tablet should be taken as a single tablet once daily.

Patients treated with an insulin secretagogue or insulin: Co-administration of the combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may require lower doses of the insulin secretagogue or insulin to reduce the risk of hypoglycemia.

The most common adverse reactions reported in ≥5% of patients simultaneously started on sitagliptin and metformin and more commonly than in patients treated with placebo were diarrhea, upper respiratory tract infection, and headache.

Adverse reactions reported in ≥5% of patients treated with sitagliptin in combination with sulfonylurea and metformin and more commonly than in patients treated with placebo in combination with sulfonylurea and metformin were hypoglycemia and headache.

Hypoglycemia was the only adverse reaction reported in ≥5% of patients treated with sitagliptin in combination with insulin and metformin and more commonly than in patients treated with placebo in combination with insulin and metformin.

Nasopharyngitis was the only adverse reaction reported in ≥5% of patients treated with sitagliptin monotherapy and more commonly than in patients given placebo.

The most common (>5%) adverse reactions due to initiation of metformin therapy are diarrhea, nausea/vomiting, fatulence, abdominal discomfort, indigestion, asthenia, and headache.

This tablet is contraindicated in patients with:

• Renal disease or renal dysfunction, e.g., as suggested by serum creatinine levels ≥1.5 mg/dL [males], ≥1.4 mg/dL [females] or abnormal creatinine clearance which may also result from conditions such as cardiovascular collapse (shock), acute myocardial infarction, and septicemia
• Acute or chronic metabolic acidosis, including diabetic ketoacidosis, with or without coma.
• History of a serious hypersensitivity reaction to this tablet or sitagliptin, such as anaphylaxis or angioedema.

This tablet should be temporarily discontinued in patients undergoing radiologic studies involving intravascular administration of iodinated contrast materials, because use of such products may result in acute alteration of renal function.

Lactic Acidosis-

• Lactic acidosis can occur due to metformin accumulation. The risk increases with conditions such as sepsis, dehydration, excess alcohol intake, hepatic insufciency, renal impairment, and acute congestive heart failure.
• Symptoms include malaise, myalgias, respiratory distress, increasing somnolence, and nonspecifc abdominal distress. Laboratory abnormalities include low pH, increased anion gap and elevated blood lactate.
• If acidosis is suspected, discontinue this tablet and hospitalize the patient immediately.
• Regular monitoring of thyroid-stimulating hormone (TSH) levels is recommended in patients with hypothyroidism.
• Long-term treatment with metformin has been associated with a decrease in vitamin B12 serum levels which may cause peripheral neuropathy. Monitoring of the vitamin B12 level is recommended.

Others-

• Do not use this tablet in patients with hepatic disease.
• There have been postmarketing reports of acute renal failure, sometimes requiring dialysis. Before initiating this tablet and at least annually thereafter, assess renal function and verify as normal.
• There have been postmarketing reports of acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis. If pancreatitis is suspected, promptly discontinue this tablet.
• Measure hematologic parameters annually.
• Warn patients against excessive alcohol intake.
• May need to discontinue this tablet and temporarily use insulin during periods of stress and decreased intake of fluids and food as may occur with fever, trauma, infection or surgery.
• Promptly evaluate patients previously controlled on this tablet who develop laboratory abnormalities or clinical illness for evidence of ketoacidosis or lactic acidosis.
• When used with an insulin secretagogue (e.g., sulfonylurea) or with insulin, a lower dose of the insulin secretagogue or insulin may be required to reduce the risk of hypoglycemia.
• There have been postmarketing reports of serious allergic and hypersensitivity reactions in patients treated with sitagliptin (one of the components of this tablet ), such as anaphylaxis, angioedema, and exfoliative skin conditions including Stevens-Johnson syndrome. In such cases, promptly stop this tablet, assess for other potential causes, and institute appropriate monitoring and treatment, and initiate alternative treatment for diabetes.
• There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP or any other anti-diabetic drug.

Cationic Drugs: Cationic drugs eliminated by renal tubular secretion: Use with caution.

Phenprocoumon: Metformin may decrease the anticoagulant effect of phenprocoumon. Therefore, close monitoring of the INR is recommended.

Levothyroxine: Levothyroxine can reduce the hypoglycemic effect of metformin. Monitoring of blood glucose levels is recommended, especially when thyroid hormone therapy is initiated or stopped, and the dosage of metformin must be adjusted if necessary.

Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women with Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP or its individual components; therefore, the safety of Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP in pregnant women is not known. This tablet should be used during pregnancy only if clearly needed.

It is not known whether sitagliptin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when this tablet is administered to a nursing woman.

Sitagliptin: In the event of an overdose, it is reasonable to employ the usual supportive measures, e.g., remove unabsorbed material from the gastrointestinal tract, employ clinical monitoring (including obtaining an electrocardiogram), and institute supportive therapy as indicated by the patient's clinical status. Sitagliptin is modestly dialyzable. Prolonged hemodialysis may be considered if clinically appropriate. It is not known if sitagliptin is dialyzable by peritoneal dialysis.

Metformin hydrochloride: Overdose of metformin hydrochloride has occurred, including ingestion of amounts greater than 50 grams. Metformin is dialyzable with a clearance of up to 170 mL/min under good hemodynamic conditions. Therefore, hemodialysis may be useful for removal of accumulated drug from patients in whom metformin overdosage is suspected. Pancreatitis may occur in the context of a metformin overdose.

Store below 25°C in a dry place away from light. Keep the medicines in a safe place, 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.

• Measure hematologic parameters annually.
• Warn patients against excessive alcohol intake.
• May need to discontinue this tablet and temporarily use insulin during periods of stress and decreased intake of fluids and food as may occur with fever, trauma, infection or surgery.
• Promptly evaluate patients previously controlled on this tablet who develop laboratory abnormalities or clinical illness for evidence of ketoacidosis or lactic acidosis.
• When used with an insulin secretagogue (e.g., sulfonylurea) or with insulin, a lower dose of the insulin secretagogue or insulin may be required to reduce the risk of hypoglycemia.
• There have been postmarketing reports of serious allergic and hypersensitivity reactions in patients treated with sitagliptin (one of the components of this tablet ), such as anaphylaxis, angioedema, and exfoliative skin conditions including Stevens-Johnson syndrome. In such cases, promptly stop this tablet, assess for other potential causes, and institute appropriate monitoring and treatment, and initiate alternative treatment for diabetes.
• There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP or any other anti-diabetic drug.

Cationic Drugs: Cationic drugs eliminated by renal tubular secretion: Use with caution.

Phenprocoumon: Metformin may decrease the anticoagulant effect of phenprocoumon. Therefore, close monitoring of the INR is recommended.

Levothyroxine: Levothyroxine can reduce the hypoglycemic effect of metformin. Monitoring of blood glucose levels is recommended, especially when thyroid hormone therapy is initiated or stopped, and the dosage of metformin must be adjusted if necessary.

Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women with Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP or its individual components; therefore, the safety of Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP in pregnant women is not known. This tablet should be used during pregnancy only if clearly needed.

It is not known whether sitagliptin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when this tablet is administered to a nursing woman.

Sitagliptin: In the event of an overdose, it is reasonable to employ the usual supportive measures, e.g., remove unabsorbed material from the gastrointestinal tract, employ clinical monitoring (including obtaining an electrocardiogram), and institute supportive therapy as indicated by the patient's clinical status. Sitagliptin is modestly dialyzable. Prolonged hemodialysis may be considered if clinically appropriate. It is not known if sitagliptin is dialyzable by peritoneal dialysis.

Metformin hydrochloride: Overdose of metformin hydrochloride has occurred, including ingestion of amounts greater than 50 grams. Metformin is dialyzable with a clearance of up to 170 mL/min under good hemodynamic conditions. Therefore, hemodialysis may be useful for removal of accumulated drug from patients in whom metformin overdosage is suspected. Pancreatitis may occur in the context of a metformin overdose.

Store below 25°C in a dry place away from light. Keep the medicines in a safe place, 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.

Biguanides

Metformin is a biguanide type oral antihyperglycemic drug used in the management of type 2 diabetes. It lowers both basal and postprandial plasma glucose. Its mechanism of action is different from those of sulfonylureas and it does not produce hypoglycemia. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucose and improves insulin sensitivity by an increase in peripheral glucose uptake and utilization.

Metformin immediate release tablet: Dosage of Metformin Hydrochloride must be individualized on the basis of both effectiveness and tolerance, while not exceeding the maximum recommended daily doses.

• Adult: The usual starting dose of Metformin is 500 mg twice a day or 850 mg once a day, given with meals. Dosage increases should be made in increments of 500 mg weekly or 850 mg every 2 weeks, up to a total of 2000 mg per day, given in divided doses. For those patients requiring additional glycemic control, Glucomin may be given to a maximum daily dose of 2550 mg per day. Doses above 2000 mg may be better tolerated given three times a day with meals.
• Children: The usual starting dose of Metformin is 500 mg twice a day, given with meals. Dosage increases should be made in increments of 500 mg weekly up to a maximum of 2000 mg per day, given in divided doses.

Metformin extended release tablet: Swallow Metformin XR tablet whole and never crush, cut or chew.

• Adult: The usual starting dose of Metformin XR is 500 mg once daily with the evening meal. Dose should be increased in increments of 500 mg weekly, up to a maximum of 2000 mg once daily with the evening meal, alternatively increased to 1000 mg twice daily taken with meal. Patient receiving Metformin immediate release tablet may be switched to Metformin extended release tablet up to a maximum recommended daily dose.
• Children: Metformin extended release tablet has not been studied in children.
• Renal impaired patient: Do not use Metformin in patients with eGFR below 30 mL/min/1.73 m². Asses risk/benefit of counting if eGFR falls below 45 mL/min/1.73 m².

Blood and lymphatic system disorders: Not known: Hemolytic anemia

Metabolism and nutrition disorders: Very rare: Lactic acidosis. Decrease of vitamin B12 absorption with a decrease of serum levels during long-term use of metformin. Consideration of such etiology is recommended if a patient presents with megaloblastic anemia. Cases of peripheral neuropathy in patients with vitamin B12 deficiency have been reported in post-marketing experience (frequency not known)

Nervous system disorders: Common: Taste disturbance. Not known: Encephalopathy

Gastrointestinal disorders: Very common: Gastrointestinal disorders, such as nausea, vomiting, diarrhea, abdominal pain, and loss of appetite. These undesirable effects occur most frequently during the initiation of therapy and resolve spontaneously in most cases. To prevent them, it is recommended that metformin be taken in 2 or 3 daily doses during or after meals. A slow increase of the dose may also improve gastrointestinal tolerability.

Hepatobiliary disorders: Very rare: Isolated reports of liver function test abnormalities or hepatitis resolving upon metformin discontinuation.

Skin and subcutaneous tissue disorders: Very rare: Skin reactions, such as erythema, pruritus, urticaria.

Metformin Hydrochloride 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. Metformin may lower vitamin B12 level. It also increases risk of hypoglycemia when use in combination with insulin or insulin secretagogue.

Co-administration with Carbonic anhydrase (Topiramate, Zonisamide) may increase risk of lactic acidosis. Drugs (Ranolazine, Dolutegravir, Cimetidine) that reduce Metformin clearance may increase the accumulation of Metformin. Alcohol can potentiate the effect of Metformin on lactate metabolism.

Pregnancy: Uncontrolled diabetes during pregnancy (gestational or permanent) is associated with an increased risk of congenital abnormalities and perinatal mortality. When the patient plans to become pregnant and during pregnancy, it is recommended that diabetes is not treated with metformin but insulin be used to maintain blood glucose levels as close to normal as possible, to reduce the risk of malformations of the foetus.

Breastfeeding: Metformin is excreted into human breast milk. No adverse efects were observed in breastfed newborns/infants. However, as only limited data are available, breastfeeding is not recommended during metformin treatment. A decision on whether to discontinue breastfeeding should be made, taking into account the benefit of breastfeeding and the potential risk to adverse effects on the child.

Elderly: Due to the potential for decreased renal function in elderly subjects, the metformin dosage should be adjusted based on renal function. Regular assessment of renal function is necessary.

Pediatric population: The diagnosis of type 2 diabetes mellitus should be confirmed before treatment with metformin is initiated. No effect of metformin on growth and puberty has been detected during controlled clinical studies of one-year duration but no long-term data on these specific points are available. Therefore, a careful follow-up of the effect of metformin on these parameters in metformin-treated children, especially prepubescent children, is recommended.

Children aged between 10 and 12 years: Particular caution is recommended when prescribing to children aged between 10 and 12 years.

Renal function: As metformin is excreted by the kidney, creatinine clearance (this can be estimated from serum creatinine levels by using the Cockcroft-Gault formula) should be determined before initiating treatment and regularly thereafter:

• At least annually in patients with normal renal function,
• At least two to four times a year in patients with creatinine clearance at the lower limit of normal and in elderly subjects.

Decreased renal function in elderly subjects is frequent and asymptomatic. Special caution should be exercised in situations where renal function may become impaired, for example when initiating antihypertensive therapy or diuretic therapy and when starting therapy with a non-steroidal anti-inflammatory drug (NSAID). GFR should be assessed before treatment initiation and regularly thereafter. Metformin is contraindicate in patients with GFR<30 ml/min and should be temporarily discontinued in the presence of conditions that alter renal function.

Hypoglycemia has not been seen with Metformin doses up to 85 gm, although lactic acidosis has occurred in such circumstances. Lactic acidosis is a medical emergency and must be treated in hospital. The most effective method to remove lactate and Metformin is hemodialysis.

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

Nalbuphine Hydrochloride is indicated for the relief of moderate to severe pain. It is used for relief of moderate to severe pain associated with myocardial infarction (MI). Nalbuphine Hydrochloride can also be used as a supplement to balanced anesthesia, for preoperative and postoperative analgesia, and for obstetrical analgesia during labor and delivery.

Opioid analgesics

Nalbuphine Hydrochloride is a synthetic potent analgesic. Its analgesic potency is essentially equivalent to that of morphine on a milligram basis. Receptor studies show that Nalbuphine binds to mu, kappa, and delta receptors, but not to sigma receptors. Nalbuphine is primarily a kappa agonist/partial mu antagonist analgesic.

The usual recommended adult dose is 10 mg for a 70 kg individual, administered subcutaneously, intramuscularly or intravenously; this dose may be repeated every 3 to 6 hours as necessary. Dosage should be adjusted according to the severity of the pain, physical status of the patient, and other medications which the patient may be
receiving.

Moderate to severe pain: by intravenous or intramuscular injection 10-20 mg for 70 kg patient, adjusted as required; child up to 0.3 mg/kg repeated once or twice as necessary.

Preoperative anesthesia: by intravenous or intramuscular injection 0.1-0.2 mg/kg.

Obstetrical analgesia during labor & delivery: by intravenous injection 0.3-1 mg/kg over 10-15 minutes with maintenance doses of 0.25-0.5 mg/kg in single intravenous administration as required.

Intraoperative analgesia: by intravenous injection 0.25-0.5 mg/kg at 30 minutes intervals.

Myocardial infarction: By slow intravenous injection 10-20 mg, repeated after 30 minutes if necessary. Larger dose is required when used as supplement of anesthesia than that required for analgesia.

Children from 18 months to 15 years old: usually 0.2 mg/ kg body-weight, given preferably by intravenous or intramuscular injection. Maintenance doses may be given at intervals of 4 to 6 hours or the dose must be determined by the physician.

Generally Nalbuphine is well tolerated. However few side-effects like sedation, sweating, nausea, vomiting, dizziness, vertigo, dry mouth, headache, respiratory depression, dyspnea and asthma may be seen.

Known hypersensitivity to Nalbuphine Hydrochloride.

Caution should be taken in the following conditions: impaired respiration, impaired renal or hepatic function, billiary tract surgery, myocardial infarction and hypotension.

No hazardous interactions have been identified with Nalbuphine; however, interactions described with other opioids may be anticipated. Patient receiving a narcotic analgesic, general anesthesia, phenothiazines or other tranquilizers, sedatives, hypnotics, or other CNS depressants (including alcohol) concomitantly with Nalbuphine may exhibit an additive effect.

Pregnancy category B. The placental transfer of Nalbuphine is high and rapid. There are no well-controlled studies in pregnant women. This drug should be used during pregnancy only if clearly needed. Limited data suggest that Nalbuphine is excreted in maternal milk but only in a small amount (less than 1% of the administered dose) and with a clinically insignificant effect. Caution should be exercised when Nalbuphine is administered to a nursing woman.

Sleepiness & mild dyspnea may occur due to overdose. The immediate intravenous administration of an opiate antagonist such as Naloxone or Nalmefene is a specific antidote. Oxygen, intravenous fluids, vasopressors and other supportive measures should be used as indicated

Keep it in a cool and dry place, protected from light and moisture.

Silymarin (Milk thistle) is indicated for the treatment and prevention of-

• Liver disease, (non-alcoholic & alcoholic)
• Liver cirrhosis, (non-alcoholic & alcoholic)
• Infectious hepatitis
• Drug-induced hepatitis
• Liver disease secondary to diabetes mellitus
• Toxicity of narcotics
• Fatty liver
• Jaundice

Cholagogues, Cholelitholytics & Hepatic Protectors, Herbal and Nutraceuticals

Silymarin, a flavonoid complex of Silybum marianum or Milk thistle, is the biologically active component. It provides hepatocellular protection through toxin blockade at the membrane level, enhances protein synthesis, antioxidant activity, anti-fibrotic activity and possible anti-inflammatory or immunomodulating effects.

1 capsule 2 to 3 times daily or as directed by a physician.

Well tolerated in the recommended dose. Occasionally a mild laxative effect may observe.

Contraindicated in patient with a known hypersensitivity to silymarin.

Concomitant use of silymarin and butyrophenones or phenothiazines has resulted in the reduction of lipid peroxidation.

No experience is available about the use of Silymarin 70 mg or 140 mg during pregnancy and lactation. Therefore, if needed Silymarin 70 mg or 140 mg should be taken with caution according to the physician’s advice.

Store in a cool & dry place, away from light & moisture. Keep out of reach of children.

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

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

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

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

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

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

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

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

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

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

Frequency is greater than 1%-

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

Frequency less than 1%-

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

Isolated cases (frequency less than 0.01%)-

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

Tenoxicam must not be administered to patients:

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

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

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

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

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

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

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

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

Alpha adrenoceptor blocking drugs, Beta-adrenoceptor blocking drugs, Beta-blockers

Carvedilol is a cardiovascular drug whose main pharmacological action is non-selective antagonism of β-adrenergic receptors but which also possesses appreciable a-adrenergic antagonistic activity. It also has antiproliferative properties and is a scavenger of reactive free oxidant radicals. It is used in the treatment of hypertension, angina pectoris and congestive heart failure.

In hypertension: initially, 12.5 mg once daily, increased after 2 days to the usual dose of 25 mg once daily; if necessary the dose may be further increased at intervals of at least 2 weeks to maximum 50 mg daily in single or divided doses. In elderly patients, the initial dose of 12.5 mg daily may provide satisfactory control.

In angina pectoris: the recommended dose for initiation of therapy is 12.5 mg twice daily for the first 2 days. Thereafter, the recommended dosage is 25 mg twice daily. For elderly patients, the maximum daily dose is 50 mg daily in divided doses.

In heart failure: initially, 3.125 mg twice daily (with food) may be given, the dose may be increased at intervals of at least 2 weeks to 6.25 mg twice daily, then to 12.5 mg twice daily, then to 25 mg twice daily. The dose may be increased to the highest dose tolerated, maximum 25 mg twice daily in patients less than 85 kg body-weight and 50 mg twice daily in patients over 85 kg.

Postural hypotension, dizziness, headache, fatigue, gastro-intestinal disturbances, bradycardia; occasionally diminished peripheral circulation, peripheral oedema and painful extremities, dry mouth, dry eyes, eye irritation or disturbed vision, impotence, disturbances of micturition, influenza-like symptoms, rarely angina, AV block, exacerbation of intermittent claudication or Raynaud's phenomenon, allergic skin reactions, exacerbation of psoriasis, nasal stuffiness, wheezing, depressed mood, sleep disturbances, paresthesia, heart failure, changes in liver enzymes, thrombocytopenia, leukopenia are also reported.

Carvedilol is contraindicated in patients with decompensated heart failure requiring intravenous inotropic therapy, bronchial asthma or related bronchospastic conditions, second or third-degree AV block, sick sinus syndrome (unless a permanent pacemaker is in place), cardiogenic shock or severe bradycardia.

Take caution in hepatic impairment and in heart failure monitor clinical status for 2-3 hours after initiation and after increasing each dose. Before increasing dose ensure that the renal function and heart failure are not deteriorating

Digoxin: In normal healthy volunteers a single dose of carvedilol taken together with a single dose of digoxin resulted in significantly increased levels of digoxin 24 hours later. Patients with congestive heart failure stabilized on digoxin have been given carvedilol concomitantly without any adverse effects. Increased monitoring of digoxin is recommended when initiating, adjusting, or discontinuing the dose of carvedilol.

Rifampin: Pretreatment with rifampin resulted in a 60% decrease in Cmax and AUC.

Warfarin: Carvedilol did not alter the in vitro plasma protein binding of warfarin.

Clonidine: β-receptor antagonists potentiate the pressor reaction which may follow the sudden withdrawal of treatment with clonidine although, in theory, the a-blocking action of carvedilol should modify the pressure rise.

Carvedilol should not be used during breast-feeding, since no studies have been performed in lactating women and animal studies have shown that carvedilol is excreted in breast milk. Safety and efficacy in children have not been established with carvedilol. Carvedilol should not be used during pregnancy as no studies have been performed in this group. Animal studies have shown that carvedilol crosses the placental barrier. No information is available on the safety and efficacy of Carvedilol use in neonates.

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

Calcitriol is indicated in-

• Post-menopausal osteoporosis
• Renal osteodystrophy
• Postsurgical hypoparathyroidism
• Idiopathic hypoparathyroidism
• Pseudohypoparathyroidism
• Secondary hyperparathyroidism in patients with moderate to severe chronic renal failure (pre-dialysis)
• Vitamin D dependent rickets

Vitamin in bone formation, Vitamin-D preparations

Calcitriol is one of the most important active metabolites of vitamin D3. It is normally formed in the kidneys from its precursor, 25-hydroxycholecalciferol. Calcitriol promotes intestinal absorption of calcium and regulates bone mineralization. The key role of Calcitriol is the regulation of calcium homeostasis, which includes stimulation effects on osteoblastic activity in the skeleton.

The optimal daily dose of Calcitriol capsule must be carefully determined for each patient on the basis of serum calcium level.

In Post-menopausal Osteoporosis: The recommended dose of Calcitriol capsule is 0.25 mcg twice daily.

In Renal Osteodystrophy (dialysis patients): The initial daily dose is 0.25 mcg of Calcitriol capsule. In patients with normal or only slightly reduced calcium levels, doses of 0.25 mcg every other day are sufficient.

In Hypoparathyroidism and Rickets: The recommended initial dosage of Calcitriol capsule is 0.25 mcg/day which given in the morning. If within 2-4 weeks satisfactory response is not observed by usual dose then dose may be increased at 2-4 weeks intervals.

The recommended intravenous initial dose of Calcitriol injection, depending on the severity of the hypocalcemia and/or secondary hyperparathyroidism, is 1 mcg (0.02 mcg/kg) to 2 mcg administered three times weekly, approximately every other day. Doses as small as 0.5 mcg and as large as 4 mcg three times weekly have been used as an initial dose. If a satisfactory response is not observed, the dose may be increased by 0.5 to 1 mcg at two to four week intervals.

Occasional symptoms include anorexia, headache, vomiting and constipation. Chronic effects may include dystrophy, fever, polyuria, dehydration, apathy and urinary tract infection.

Calcitriol is contraindicated in patients with known hypersensitivity to any of its ingredients. Calcitriol is also contraindicated in all diseases associated with hypercalcemia.

During Calcitriol therapy if the serum calcium levels rise to 1 mg/100 ml above normal or serum creatinine rises to >120 µmol/l, the dosage of Calcitriol should be substantially reduced or treatment stopped.

Concomitant treatment with a thiazide diuretics increases the risk of hypercalcemia. Calcitriol dosage must be determined with care in patients undergoing treatment with digitalis as hypercalcemia in such patients may precipitate cardiac arrhythmias. Magnesium containing drugs (e.g.,antacids) may cause hypermagnesemia.

There is no evidence that vitamin D is teratogenic in humans. Calcitriol may be used during pregnancy only if the benefits outweigh the potential risk to the fetus. Mothers may breast feed while taking Calcitriol but serum calcium levels of the mother and infant should be monitored.

Secondary hyperparathyroidism in patients with moderate to severe chronic renal failure (pre-dialysis)-

• The recommended initial dosage of Calcitriol is 0.25 mcg/day in adults and pediatric patients 3 years of age or older. This dosage may be increased if necessary to 0.5 mcg/day.
• For pediatric patients less than 3 years of age, the recommended initial dosage of Calcitriol is 10 to 15 ng/kg/day.
• In Elderly: No dosage adjustment are required.

Vitamin-C Preparations

vitamin C, the water-soluble vitamin, is readily absorbed from the gastrointestinal tract and is widely distributed in the body tissues. It is believed to be involved in biological oxidations and reductions used in cellular respiration. It is essential for the synthesis of collagen and intracellular material. Vitamin C deficiency develops when the dietary intake is inadequate and when increased demand is not fulfilled. Deficiency leads to the development of well defined syndrome known as scurvy, which is characterized by capillary fragility, bleeding (especially from small blood vessels and the gums), anaemia, cartilage and bone lesions and slow healing of wounds.

Oral administration-

• For the prevention of scurvy: 1 tablet daily
• For the treatment of scurvy: 1-2 tablets daily; but dose may be increased depending on the severity of the condition.
• For the reduction of risk of stroke in the elderly: 1-2 tablets daily.
• In other cases: 1 tablet daily or as directed by the physician.
• Maximum safe dose is 2000 mg daily in divided doses.

Parenteral administration-

• Vitamin C is usually administered orally. When oral administration is not feasible or when malabsorption is suspected, the drug may be administered IM, IV, or subcutaneously. When given parenterally, utilization of the vitamin reportedly is best after IM administration and that is the preferred parenteral route.
• For intravenous injection, dilution into a large volume parenteral such as Normal Saline, Water for Injection, or Glucose is recommended to minimize the adverse reactions associated with intravenous injection.
• The average protective dose of vitamin C for adults is 70 to 150 mg daily. In the presence of scurvy, doses of 300 mg to 1 g daily are recommended. However, as much as 6 g has been administered parenterally to normal adults without evidence of toxicity.
• To enhance wound healing, doses of 300 to 500 mg daily for a week or ten days both preoperatively and postoperatively are generally considered adequate, although considerably larger amounts have been recommended. In the treatment of burns, doses are governed by the extent of tissue injury. For severe burns, daily doses of 1 to 2 g are recommended. In other conditions in which the need for vitamin C is increased, three to five times the daily optimum allowances appear to be adequate.
• Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever the solution and container permit.

Vitamin C has little toxicity and only mega-doses of vitamin C may cause diarrhoea, abdominal bloating, iron over-absorption that is harmful in patients with thalassaemia, sideroblastic anemia, and haemochromatosis; hyperoxaluria, hyperuricosuria, and hemolysis in patients with glucose-6 phosphate dehydrogenase deficiency. A pregnant woman taking more than 5 gm/day may suffer fetal abortion.

Ingestion of megadose (more than 1000 mg daily) of vitamin C during pregnancy has resulted in scurvy in neonates. Vitamin C in mega-doses has been contraindicated for patients with hyperoxaluria. Vitamin C itself is a reactive substance in the redox system and can give rise to false positive reactions in certain analytical tests for glucose, uric acid, creatine and occult blood.

Potentially hazardous interactions: Ascorbic acid is incompatible in solution with aminophylline, bleomycin, erythromycin, lactobionate, nafcillin, nitrofurantoin sodium, conjugated oestrogen, sodium bicarbonate, sulphafurazole diethanolamine, chloramphenicol sodium succinate, chlorthiazide sodium and hydrocortisone sodium succinate.

Useful interactions: Ascorbic acid increases the apparent half-life of paracetamol and enhances iron absorption from the gastrointestinal tract.

The drug is safe in normal doses in pregnant women, but a daily intake of 5 gm or more is reported to have caused abortion. The drug may be taken safely during lactation.

Should be stored in a dry place below 30˚C.
