Naproxen & Esomeprazole is indicated for the relief of signs & symptoms of-

• Osteoarthritis
• Rheumatoid arthritis
• Ankylosing spondylitis &
• To decrease the risk of developing gastric ulcers in patients at risk of developing NSAID-associated gastric ulcers.

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

This consists of an immediate release Esomeprazole Magnesium layer & an enteric-coated Naproxen core. As a result, Esomeprazole is released first into the stomach, prior to the dissolution of Naproxen in the small intestine.

Naproxen is a NSAID with analgesic & antipyretic properties. The mechanism of action of Naproxen is to inhibit the prostaglandin synthesis. Esomeprazole is a proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the H⁺/k⁺ -ATPase in the gastric parietal cell by acting specifically on the proton pump, Esomeprazole blocks the final step in acid production, thus reducing gastric acidity.

Carefully consider the potential benefits & risks of this tablet & other treatment options before deciding to use this tablet. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals. If a dose of Esomeprazole lower than a total daily dose of 40 mg is more appropriate, a different treatment should be considered.

Rheumatoid Arthritis, Osteoarthritis and Ankylosing Spondylitis-

• Adults: One tablet twice daily of either: 375 mg naproxen/20 mg of esomeprazole; or 500 mg naproxen/20 mg of esomeprazole

Juvenile Idiopathic Arthritis in Adolescent Patients 12 Years of Age & Older-

• Weight greater than 50 kg: 375 mg naproxen/20 mg of esomeprazole; or 500 mg naproxen/20 mg of esomeprazole
• Weight 38 kg to less than 50 kg: One tablet twice daily of 375 mg naproxen/20 mg of esomeprazole.

Do not split, chew, crush or dissolve the tablet. This tablet is to be taken at least 30 minutes before meals.

In general, this preparation is well tolerated. The most common adverse reactions in clinical trials (>5%): erosive gastritis, dyspepsia, gastritis, diarrhea, gastric ulcer, upper abdominal pain, nausea etc.

Patients with known CV disease/risk factors may be at greater risk. This tablet should be used with caution in patients with fluid retention or heart failure.

With medicine:

• Concomitant use of NSAIDs may reduce the antihypertensive effect of ACE inhibitors, diuretics & beta-blockers
• Concomitant use of this tablet and warfarin may result in an increased risk of a bleeding complication.
• Esomeprazole inhibits gastric acid secretion & may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (eg. Ketoconazole, iron salts and digoxin).

With food & others: Administration of Naproxen & Esomeprazole together with high-fat food in healthy volunteers does not affect the extent of absorption of naproxen but significantly prolongs t_max by 10 hours and decreases peak plasma concentration (C_max) by about 12%

Pregnancy category C. In late pregnancy, it should be avoided because it may cause premature closure of the ductus arteriosus. This tablet should not be used in nursing mothers due to the Naproxen component.

Elderly patients: Studies indicate that although the total plasma concentration of naproxen is unchanged, the unbound plasma fraction of naproxen is increased in the elderly. Use caution when high doses are required & some adjustment of dosage may be required in elderly patients. As with other drugs used in the elderly use the lowest effective dose.

Patients with Moderate to Severe Renal impairment: Naproxen-containing products are not recommended for use in patients with moderate to severe or severe renal impairment (creatinine clearance <30 ml/min).

Hepatic insufficiency: Monitor patients with mild to moderate hepatic impairment closely & consider a possible dose reduction based on the Naproxen component of this tablet. This is not recommended in patients with severe hepatic impairment because Esomeprazole dosage should not exceed 20 mg daily in these patients.

There is no clinical data on overdosage with this tablet.

Overdose of Naproxen: Significant naproxen overdosage may be characterized by lethargy, drowsiness, epigastric pain, abdominal discomfort, heartburn, indigestion, nausea, transient alteration in liver function, hypoprothrombinemia, renal dysfunction, metabolic acidosis, apnea, vomiting etc.

Overdose of Esomeprazole: The major signs of acute toxicity were reduced motor activity, changes in respiratory frequency, tremor and intermittent clonic convulsions etc.

Store at temperature of below 30°C, protect from light & moisture. Keep out of reach of children.

Amantadine Hydrochloride is indicated for-

• Treatment of parkinsonism
• Treatment of drug-induced extrapyramidal reactions
• Prophylaxis and treatment of signs and symptoms of infection caused by various strains of influenza A virus

Respiratory viral infections (Influenza)

The mechanism by which amantadine exerts its antiviral activity is not clearly understood. It appears to mainly prevent the release of infectious viral nucleic acid into the host cell by interfering with the function of the transmembrane domain of the viral M2 protein. In certain cases, amantadine is also known to prevent virus assembly during virus replication. It does not appear to interfere with the immunogenicity of inactivated influenza A virus vaccine.

Amantadine inhibits the replication of influenza A virus isolates from each of the subtypes, i.e., H1N1, H2N2 and H3N2. It has very little or no activity against influenza B virus isolates. A quantitative relationship between the in vitrosusceptibility of influenza A virus to amantadine and the clinical response to therapy has not been established in man. Sensitivity test results, expressed as the concentration of amantadine required to inhibit by 50% the growth of virus (ED50) in tissue culture vary greatly (from 0.1 µg/mL to 25.0 µg/mL) depending upon the assay protocol used, size of virus inoculum, isolates of influenza A virus strains tested, and the cell type used. Host cells in tissue culture readily tolerated amantadine up to a concentration of 100 µg/mL.

Parkinson's disease:

• Adult: Initially, 100 mg/day, increased to 100 mg bid after a wk or more. Max dose: 400 mg daily.
• Elderly: >65 yr: Lowest effective dose.

Prophylaxis of influenza A:

• Adult: 100 mg daily for up to 6 wk; when used with influenza vaccination: only up to 3 wk after vaccination.
• Child: 10-15 yr: 100 mg daily.

Influenza A:

• Adult: 100 mg daily for 5 days.
• Elderly: >65 yr: Daily dose of 1 day.

Herpes zoster in immunocompromised patients:

• Adult: 100 mg bid for 14 days, continued for another 14 days if pain persists.

The adverse effects of Amantadine are generally mild and, when they occur, may diminish or cease after a week or more on the medication. The most commonly reported side effects include nausea, dizziness/ lightheadedness, and insomnia.

Other side effects may include edema of ankles, livedo reticularis; anxiety, elevation of mood, headache, lethargy, hallucinations, ataxia, slurred speech, blurred vision, loss of concentration, nervousness, depression, myalgia, palpitations, orthostatic hypotension, dry mouth, anorexia, constipation and diaphoresis.

Amantadine is contraindicated in patients with known hypersensitivity to the active substances or to any of the excipients.

Amantadine should not be discontinued abruptly in patients with Parkinson's disease since a few patients have experienced a parkinsonian crisis, i.e., a sudden marked clinical deterioration, when this medication was suddenly stopped. The dose of anticholinergic drugs or of Amantadine Hydrochloride should be reduced if atropine-like effects appear when these drugs are used concurrently. Abrupt discontinuation may also precipitate delirium, agitation, delusions, hallucinations, paranoid reaction, stupor, anxiety, depression and slurred speech.

Concurrent administration of Amantadine and anticholinergic agents or levodopa may increase confusion, hallucinations, nightmares, gastro-intestinal disturbances, or other atropine-like side effects. Psychotic reactions have been observed in patients receiving Amantadine and Levodopa.

Concurrent administration of Amantadine and drugs or substances (e.g. alcohol) acting on the CNS may result in additive CNS toxicity. Close observation is recommended.

Pregnancy category C. No well-controlled studies have been done in pregnant women to evaluate Amantadine's safety. Amantadine may be used during pregnancy when the potential benefits outweigh the potential but unknown risks to the fetus.

Amantadine is excreted into breast milk in low concentrations. As no information is available on the effects in infants, therefore amantadine should be used cautiously in women who are breastfeeding.

Patients with renal impairment:  The dose should be reduced. This can be achieved by either reducing the total daily dose, or by increasing the dosage interval in accordance with the creatinine clearance. For example:

• CrCl <15 ml/min: Contraindicated
• CrCl 15-35 ml/min: 100 mg every 2 to 3 days
• CrCl >35 ml/min: 100mg every day

Patients with hepatic impairment: Use with caution

Store at 20-25°C in dry place. Protect from light.

Patients with hepatic impairment: Use with caution

Store at 20-25°C in dry place. Protect from light.

Prophylaxis of influenza (flu), especially in those who run an increased risk of associated complications. The use of Inactivated Influenza Vaccine should be based on official recommendations.

Vaccines, Anti-sera & Immunoglobulin

Dosage:

• Adults and children over 36 months of age: 0.5ml
• Children from 6 to 35 months of age: clinical data are limited. Doses of 0.25 ml or 0.5 ml have been used.

Administrations: For children who have not previously been vaccinated, a second dose should be given after an interval of at least 4 weeks. If half a dose (0.25 ml) is to be administered, discard half the contained volume (up to the mark indicated on the syringe barrel), before injection. Immunisation should be carried out by intramuscular or deep subcutaneous injection. The vaccine should be allowed to reach room temperature before use. Shake before use. Seroprotection is generally obtained within 2 to 3 weeks. The duration of postvaccinal immunity to homologous strains or to strains closely related to the vaccine strains varies but is usually 6-12 months.

Hypersensitivity to the active substances, to any of the excipients and to residues, e.g. eggs, chicken proteins, such as ovalbumin. The vaccine may contain residues of the following substances, e.g. kanamycin and neomycin sulphate, formaldehyde, cetyltrimethylammonium bromide (CTAB) and polysorbate 80. Immunisation shall be postponed in patients with febrile illness or acute infection.

Antibody response in patients with endogenous (due to illness) or iatrogenic (due to medicine) immunosuppression (poor immune response) may be insufficient. As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of a rare anaphylactic event following the administration of the vaccine. Inactivated Influenza Vaccine should under no circumstances be administered intravascularly.

Inactivated Influenza Vaccine may be given at the same time as other vaccines. Immunisation should be carried out on separate limbs. It should be noted that the adverse reactions may be intensified. The immunological response may be diminished if the patient is undergoing immunosuppressant treatment. Following influenza vaccination, false positive results in serology tests using the ELISA method (blood test) to detect antibodies against HIV1, Hepatitis C and especially HTLV1 have been observed. The Western Blot technique disproves the false-positive ELISA results. The transient false positive reactions could be due to the IgM response by the vaccine.

The limited data from vaccinations in pregnant women do not indicate that adverse foetal and maternal outcomes were attributable to the vaccine. The use of this vaccine may be considered from the second trimester of pregnancy. For pregnant women with medical conditions that increase their risk of complications from influenza, administration of the vaccine is recommended, irrespective of their stage of pregnancy. Inactivated Influenza Vaccine may be used during lactation.

Inactivated Influenza Vaccine must be stored in a refrigerator (2°C-8°C). Do not freeze. Keep the syringe in the outer carton in order to protect from light. Any unused product or waste material should be disposed of in accordance with local requirements.

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.

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.

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.

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.

Adefovir Dipivoxil is indicated for the treatment of chronic hepatitis B in adults with evidence of active viral replication and either evidence of persistent elevations in serum aminotransferases (ALT or AST) or histologically active disease.

Hepatic viral infections (Hepatitis B)

Adefovir dipivoxil is a diester prodrug of adefovir. Adefovir is an acyclic nucleotide analog with activity against human hepatitis B virus (HBV). Adefovir is phosphorylated to the active metabolite, adefovir diphosphate, by cellular kinases. Adefovir diphosphate inhibits HBV DNA polymerase (reverse transcriptase) by competing with the natural substrate deoxyadenosine triphosphate and by causing DNA chain termination after its incorporation into viral DNA. The approximate oral bioavailability of adefovir from a 10 mg single dose is 59%. In vitro binding of adefovir to human plasma or human serum proteins is 4%. Adefovir is excreted through renal route by a combination of glomerular filtration and active tubular secretion.

The recommended dose of Adefovir in chronic hepatitis B patients with adequate renal function is 10 mg, once daily, taken orally, without regard to food.

The most common side effects of adefovir dipivoxil are weakness, headache, stomach pain and nausea. Severe acute exacerbations of hepatitis have been reported in patients who have discontinued anti-hepatitis B therapy, including therapy with adefovir dipivoxil. In patients at risk of or having underlying renal dysfunction, chronic administration of adefovir dipivoxil may result in nephrotoxicity. Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogs alone or in combination with other antiretrovirals.

Adefovir dipivoxil is contraindicated in patients with previously demonstrated hypersensitivity to any of the components of the product.

Patients who discontinued adefovir dipivoxil should be monitored at repeated intervals over a period of time for hepatic function. The patients at risk of or having underlying renal dysfunction should be monitored closely for renal function and may require dose adjustment.

The pharmacokinetics of adefovir was unchanged when adefovir dipivoxil was coadministered with lamivudine, trimethoprim/ sulfamethoxazole and acetaminophen. When adefovir dipivoxil was co-administered with ibuprofen (800 mg three times daily), increases in adefovir Cmax (33%), AUC (23%) and urinary recovery were observed due to higher oral bioavailability of adefovir.

Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Adefovir dipivoxil should be used during pregnancy only if clearly needed and after careful consideration of the risks and benefits. It is not known whether adefovir is excreted in human milk. Mothers should be instructed not to breast-feed if they are taking adefovir dipivoxil.

Pediatric use: Safety and effectiveness in pediatric patients have not been established.

Geriatric use: In general, caution should be exercised when prescribing to elderly patients since they have greater frequency of decreased renal or cardiac function due to concomitant disease or other drug therapy.

Dose Adjustment in Renal Impairment: the dosing interval of Adefovir should be adjusted in patients with baseline creatinine clearance <50 ml/min using the following suggested guidelines:

• CrCl ≤ 50 ml/min: 10 mg
• CrCl 20-49 ml/min: 10 mg every 48 hours
• CrCl 10-19 ml/min: 10 mg every 72 hours
• Haemodialysis patients: 10 mg every 7 days following dialysis

Doses of adefovir dipivoxil 500 mg daily for 2 weeks and 250 mg daily for 12 weeks have been associated with gastrointestinal side effects. If overdose occurs the patient must be monitored for evidence of toxicity and standard supportive treatment applied as necessary.

Store at cool and dry place. Protect from light and moisture. Keep all the medicines out of the reach of children.

Other Antifungal preparations, Topical Antifungal preparations

Terbinafine, an Allylamine antifungal, inhibits biosynthesis of Ergosterol (an essential component of fungai cell membrane) via inhibition of Squalene Epoxidase enzyme. This results in fungal cell death primarily due to the increased membrane permeability mediated by the accumulation of high concentrations of Squalene but not due to Ergosterol deficiency. Depending on the concentration of the drug and the fungal species test in vitro, Terbinafine hydrochloride may be fungicidal. However, the clinical significance of in vitro data is unknown. Terbinafine has been shown to be active against most strains of the following microorganisms both in vitro and in clinical infections: Tricophyton Mentagrophyte, Trichophyton Rubrum.

Terbinafine tablet:

• For the treatment of fingernail onychomycosis: Terbinafine 250 mg (one tablet), once daily for 6 weeks.
• For the treatment of toenail onychomycosis: Terbinafine 250 mg (one tablet), once daily for 12 weeks.
• The optimal clinical effect is seen some months after mycological cure and cessation of treatment. This is related to the period required for the outgrowth of healthy nail.

Terbinafine granules:

• Body Weight: <25 kg: 125 mg/day up to 6 weeks
• Body Weight: 25-35 kg: 187.5 mg/day up to 6 weeks
• Body Weight: >35 kg: 250 mg/day up to 6 weeks

Terbinafine cream: Terbinafine cream can be applied once or twice daily. Cleanse and dry the affected areas thoroughly before application of the terbinafine cream. Apply the cream to the affected skin and the surrounding area in a thin layer and rub in lightly. In the case of intertriginous infections (submammary, interdigital, intergluteal, inguinal) the application may be covered with a gauze strip, especially at night. The likely durations of treatment are as follows:

• Tinea corporis, cruris: 1 to 2 weeks
• Tinea pedis: 1 week
• Cutaneous candidiasis: 2 weeks
• Pityriasis versicolor: 2 weeks

Relief of the clinical symptoms usually occurs within a few days. Irregular use or premature discontinuation of treatment carries the risk of recurrence. If there are no signs of improvement after two weeks, the diagnosis should be verified.

Terbinafine 1% Spray: This spray is applied once or twice daily, depending on the indication. The affected areas should be cleansed and dried thoroughly before application of this spray. A sufficient amount of solution should be applied to wet the treatment area(s) thoroughly.

• Tinea pedis: once a day,1 week
• Tinea corporis/cruris: once a day,1 week
• Pityriasis versicolor: twice a day, 1 week

Relief of clinical symptoms usually occurs within a few days. If there are no signs of improvement after two weeks the diagnosis should be verified.

The adverse events reported encompass gastrointestinal symptoms (including diarrhea, dyspepsia and abdominal pain), liver test abnormalities, rashes, urticaria, pruritus, and taste disturbances. In general, the adverse events were mild, transient, and did not lead to discontinuation. Adverse events, based on worldwide experience with terbinafine use, include: idiosyncratic and symptomatic hepatic injury and more rarely, cases of liver failure, some leading to death or liver transplant, serious skin reactions, severe neutropenia, thrombocytopenia, angioedema and allergic reactions (including anaphylaxis). Other adverse reactions that have been reported include malaise, fatigue, vomiting, arthralgia, myalgia, and hair loss.

Terbinafine tablet and cream are contra-indicated in individuals with hypersensitive to terbinafine.

Warnings-

• Terbinafine tablets: Rare cases of liver failure, some leading to death or liver transplant, have occurred with the use of terbinafine tablets for the treatment of onychomycosis in individuals with and without preexisting liver disease. In the majority of liver cases reported in association with terbinafine use, the patients had serious underlying systemic conditions and an uncertain causal association with terbinafine. The severity of hepatic events and/or their outcome may be worse in patients with active or chronic liver disease. Treatment with terbinafine tablets should be discontinued if there is biochemical or clinical evidence of liver injury. There have been isolated reports of serious skin reaction (e.g., Stevens-Johnson Syndrome and toxic epidermal necrolysis). If progressive skin rash occurs, treatment with terbinafine should be discontinued.
• Terbinafine cream: Terbinafine cream is for external use only. Contact with the eyes should be avoided.

Precautions: Terbinafine are not recommended for patients with chronic or active liver disease. Before prescribing Terbinafine, pre-existing liver disease should be assessed. Hepatotoxicity may occur in patients with and without pre-existing liver disease. Pretreatment serum transaminase (ALT and AST) teste are advised for all patients before taking terbinafine tablets.

In vivo studies have shown that terbinafine is an inhibitor of the CYP450 2D6 isozyme. Drugs predominantly metabolized by the CYP450 2D6 isozyme include the following drug classes: tricyclic antidepressants, selective serotonin reuptake inhibitors, beta-blockers, antiarrhythmics class 1C (e.g., flecainide and propafenone) and monoamine oxidase inhibitors Type B. Co-administration of terbinafine should be done with careful monitoring and may require a reduction in dose of the 2D6-metabolized drug.

Terbinafine tablet: There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, and because treatment of onychomycosis can be postponed until after pregnancy is completed, it is recommended that terbinafine not be initiated during pregnancy. After oral administration, terbinafine is present in the breast milk of nursing mothers. Treatment with terbinafine is not recommended in nursing mothers.

Terbinafine cream: Foetal toxicity and fertility studies in animals suggest no adverse effects. There is no clinical experience with terbinafine in pregnant women; therefore, unless the potential benefits outweigh any potential risk, terbinafine should not be administered. Terbinafine is excreted in breast milk and therefore mothers should not receive terbinafine treatment whilst breast-feeding.

Pediatric use: The safety and efficacy of terbinafine have not been established in pediatric patients.

Use in the elderly: There is no evidence to suggest that elderly patients require different dosages or experience side-effects different to those of younger patients.

Clinical experience regarding overdose with terbinafine tablets is limited. Doses up to 5 gm (20 times the therapeutic daily dose) have been taken without inducing serious adverse reactions. The symptoms of overdose included nausea, vomiting, abdominal pain, dizziness, rash, frequent urination, and headache.

Store in a cool and dry place, below 30°C, protect from light.

Intravenous fluid preparations

Dextrose is a form of glucose (sugar). Dextrose 5% in water is injected into a vein through an IV to replace lost fluids and provide carbohydrates to the body. Dextrose 5% in water is used to treat low blood sugar (hypoglycemia), insulin shock, or dehydration (fluid loss). Dextrose 5% in water is also given for nutritional support to patients who are unable to eat because of illness, injury, or other medical condition.

5% dextrose solution: The dose of Dextrose infusion is variable. It is dependent on individual patient requirements. For 5% dextrose solution, the dose frequently ranges from 500 to 1000 ml. The maximum rate of infusion that will not cause glycosuria is 0.5 g/kg/hour. About 95% is retained when the rate is 0.8 g/kg/hr. the maximum rate of glucose utilization is about 800 mg per kg body weight per hour.

25% dextrose solution: The volume and rate of infusion of dextrose solution will depend upon the requirements of the individual patient and the judgment of the physician. The maximum rate at which dextrose can be infused without producing glycosuria is 0.5 g/kg/hr. The usual recommended flow rate for adult is 10-35 drops per minute infused intravenously. It should not be administered by SC or IM route. 25% dextrose solution should be infused through the largest available peripheral vein.

Do not take this medicine and tell your doctor if: You should not use this medication if you are allergic to dextrose. Before using dextrose 5% in water, tell your doctor if you have diabetes, breathing problems, an electrolyte imbalance, kidney or liver disease, a food or drug allergy, or if you receive regular blood transfusions.

Serum glucose concentration should be carefully monitored. Concurrent use of insulin may be needed in case of diabetic patients. Dextrose solution should not be mixed with whole blood as haemolysis and clumping may occur. Infusion of fluid should be immediately discontinued if rigor arises for any reasons during the process. Do not use if the solution is cloudy, contains particles, or after expiry date.
