Gabapentin is indicated for-

• Neuropathic Pain.
• Adjunctive therapy in partial seizure and secondary generalized seizure.

Adjunct anti-epileptic drugs

Gabapentin is an anti-convulsant. It is a structural analog of gamma-amino-butyric-acid (GABA). All pharmacological actions following administration of Gabapentin are due to the activity of parent compound. Gabapentin binds with the alpha-2-delta subunit of voltage gated L-type Calcium channel, and inhibits branched chain amino acid transferase & probably inhibits neurotransmitter release of excitatory amino acid.

Neuropathic Pain: The treatment may be initiated as a single 300 mg dose on Day-1, than 300 mg twice on Day-2 and 300 mg thrice on Day-3. The dose can be subsequently be titrated up as needed for pain relief to a daily dose of 1800 mg (divided TID).

Epilepsy:

• Patients over 12 years of age: the effective dose of Gabapentin is 900 to 1800 mg/day given in three divided doses. The starting dose is 300 mg three times a day.
• Paediatric patients age 3-12 year: the starting dose should range from 10-15 mg/kg/day in 3 divided doses, and the effective dose reached by upward titration over a period of approximately three days.

Gabapentin can be taken orally with or without food.

Fatigue, Dizziness, ataxia, weight gain, peripheral edema, dry mouth and somnolence may occur.

Gabapentin is contraindicated in patients who have known hypersensitivity to the drug.

Patients should be instructed to take Gabapentin only as prescribed. While using Gabapentin patients should be instructed either not to drive a car or to operate other complex machinery until they have gained sufficient experiences about Gabapentin whether or not it affects their mental and/or motor performance adversely.

Antacids may reduce the bioavailability of Gabapentin by up to 20 %. Cimetidine may alter its reanal excretion. Gabapentin does not interact with other anti-epileptic drug or with oral contraceptive preparations.

Pregnancy category C. it should be used during pregnancy only if potential benefits justifies the potential risk to the fetus. Gabapentin may be secreted through the breast milk. So it should be used during lactation only if potential benefits justifies the potential risk to the baby.

In case of renal impaired patients Gabapentin doses must be reduced.

Store below 25°C temperature. Protect from light and moisture. Keep all the medicines out of the reach of the children.

Vitamin B1, B6 & B12 is indicated for the treatment of vitamin B1, B6 & B12 deficiency syndrome. It is also indicated for the supportive treatment of neuritis & non-inflammatory diseases of the nerves, e.g.- Diabetic neuropathy, Peripheral neuralgin, Lumbago, Myalgia, Optic neuritis, Sciatica, Facial neuralgia, Intercostal neuralgia, Spinal pain.

Specific combined vitamin preparations

Vitamin B1 converts carbohydrates, fatty acids and amino acids into energy, promotes healthy nerves, improves mood, strengthens the heart. Vitamin B6 forms RBCs, helps cells to make proteins, manufactures neurotransmitters e.g. serotonin and releases stored forms of energy, helps to prevent CVS diseases and stroke, helps to lift depression and eases insomnia. Vitamin B12 is essential for cell replication and important for RBC production, prevents anemia, helps to prevent depression, reduces nerve pain, numbness, tingling and lowers the risk of heart diseases.

The vitamin ingredients are absorbed well in per oral reception. It is widely distributed to most tissues and appears in breast milk. Within the cell, thiamine is mostly present as diphosphate. Thiamine is not stored to any appreciable extent in the body and amounts in excess of the body’s requirements are excreted in the urine as unchanged thiamine or as metabolites. Pyridoxine, pyridoxal and pyridoxamine are readily absorbed from the GIT following oral administration and are converted to the active forms of pyridoxal phosphate an pyridoxamine phosphate. They are stored mainly in liver where there is oxidation to 4-pyridoxic acid and other inactive metabolites, which are excreted in urine. As the dose increases, proportionally greater amounts are excreted unchanged in the urine.

Tablet: 1-3 Tablets per day or as advised by the physician.

Injection:

• In severe (acute) cases: 1 injection daily until the acute symptoms subside or taken as advised by the physician.
• In mild cases: 1 injection 2-3 times per week. Ampoules are preferably injected intramuscularly.

Use in children: There is no information on the use of this drug in children.

Generally well tolerated but allergic reactions may be observed in few cases.

Vitamin B1, Vitamin B6 and Vitamin B12 is contraindicated in patients on levodopa therapy, and in patients with hypersensitivity to any of the ingredients of the preparation.

Cyanocobalamin should not be given in patients with subacute degeneration of the spinal cord. Cyanocobalamin is not suitable form of vitamin B12 for the treatment of optic neuropathies associated with raised plasma concentrations of cyanocobalamin.

No drug interaction has been reported yet.

Oral tablet form is recommended but due to the presence of benzyl alcohol, injection is not recommended during pregnancy & lactation.

No overdosage symptoms are to be expected in the recommended dosage. If there is known overdose then treatment is symptomatic & supportive.

Adjunct anti-epileptic drugs, Primary anti-epileptic drugs

Pregabalin is a structural derivative of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). It does not bind directly to GABA_A, GABA_B or benzodiazepine receptors. Pregabalin binds with high affinity to the alpha2-delta site (an auxiliary subunit of voltage-gated calcium channels) in central nervous system tissues. Although the mechanism of action of Pregabalin has not been fully elucidated, results in animal studies suggest that binding to the alpha2-delta subunit may be involved in Pregabalin's anti-nociceptive and antiseizure effects.

Neuropathic pain associated with diabetic peripheral neuropathy in adults (DPN): The maximum recommended dose of Pregabalin is 100 mg three times a day (300 mg/day) in patients with creatinine clearance of at least 60 ml/min. Dosing should begin at 50 mg three times a day (150 mg/day). The dose may be increased to 300 mg/day within 1 week based on efficacy and tolerability. Begin dosing of Pregabalin CR capsule at 165 mg once daily and increase to 330 mg once daily within 1 week based on individual patient response and tolerability. The maximum recommended dose of Pregabalin CR capsule is 330 mg once daily.

Postherpetic neuralgia in adults (PHN): The recommended dose of Pregabalin is 75 to 150 mg two times a day or 50 to 100 mg three times a day (150 to 300 mg/day) in patients with creatinine clearance of at least 60 ml/min. Dosing should begin at 75 mg two times a day or 50 mg three times a day (150 mg/day). The dose may be increased to 300 mg/day within 1 week based on efficacy and tolerability. Patients who do not experience sufficient pain relief following 2 to 4 weeks of treatment with 300 mg/day and who are able to tolerate Pregabalin, may be treated with up to 300 mg two times a day or 200 mg three times a day (600 mg/day).

Begin dosing of Pregabalin CR capsule at 165 mg once daily and increase to 330 mg once daily within 1 week based on individual patient response and tolerability. Patients who do not experience sufficient pain relief following 2 to 4 weeks of treatment with 330 mg once daily and who are able to tolerate Pregabalin CR capsule, may be treated with up to 660 mg once daily. In view of the dose-dependent adverse reactions and the higher rate of treatment discontinuation due to adverse reactions, dosing above 330 mg/day should be reserved only for those patients who have on-going pain and are tolerating 330 mg daily. The maximum recommended dose of Pregabalin CR capsule is 660 mg once daily.

Management of fibromyalgia in adults: The recommended dose of Pregabalin is 300 to 450 mg/day. Dosing should begin at 75 mg two times a day (150 mg/day). The dose may be increased to 150 mg two times a day (300 mg/day) within 1 week based on efficacy and tolerability. Patients who do not experience sufficient benefit with 300 mg/day may be further increased to 225 mg two times a day (450 mg/day).

Neuropathic pain associated with spinal cord injury in adults: The recommended dose range of Pregabalin is 150 to 600 mg/day. The recommended starting dose is 75 mg two times a day (150 mg/day). The dose may be increased to 150 mg two times a day (300 mg/day) within 1 week based on efficacy and tolerability. Patients who do not experience sufficient pain relief after 2 to 3 weeks of treatment with 150 mg two times a day and who tolerate Pregabalin may be treated with up to 300 mg two times a day.

Conversion from Pregabalin capsules to Pregabalin CR capsule tablet: When switching from Pregabalin capsules to Pregabalin CR capsule tablet on the day of the switch, instruct patients to take their morning dose of Pregabalin capsule as prescribed and initiate Pregabalin CR capsule therapy after an evening meal.

Pregabalin tablet total daily dose (dosed 2 or 3 times daily): Pregabalin CR capsule capsule dose (dosed once a day)

• 75 mg/daily: 82.5 mg/day
• 150 mg/daily: 165 mg/day
• 225 mg/daily: 247.5 mg/day
• 300 mg/daily: 330 mg/day
• 450 mg/daily: 495 mg/day
• 600 mg/daily: 660 mg/day

Route of administration: Pregabalin is taken in oral route. It can be taken with or without food. Pregabalin CR tablet should be administered after an evening meal. It should be swallowed whole and should not be split, crushed or chewed. If patients miss taking their dose of Pregabalin CR after an evening meal, then they should take their usual dose of Pregabalin CR prior to bedtime following a snack. If they miss taking the dose of Pregabalin CR prior to bedtime, then they should take their usual dose of Pregabalin CR following a morning meal. If they miss taking the dose of Pregabalin CR following the morning meal, then they should take their usual dose of Pregabalin CR at the usual time that evening following an evening meal. When discontinuing both Pregabalin and Pregabalin CR, it should be gradually tapered over a minimum of 1 week.

Most common side effects in adults are dizziness, somnolence, dry mouth, edema, blurred vision, weight gain and thinking abnormal (primarily difficulty with concentration/attention). Most common side effects in pediatric patients for the treatment of partial onset seizures are increased weight and increased appetite.

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

Angioedema (e.g., swelling of the throat, head and neck) can occur and may be associated with life threatening respiratory compromise requiring emergency treatment. Pregabalin should be discontinued immediately in these cases. Pregabalin should also be discontinued immediately if hypersensitivity reactions (e.g., hives, dyspnea and wheezing) occur. Antiepileptic drugs, including pregabalin, increase the risk of suicidal thoughts or behavior. Respiratory depression may occur with pregabalin when used with concomitant CNS depressants or in the setting of underlying respiratory impairment. Patients need to be monitored and dosage adjusted as appropriate. Pregabalin may cause dizziness and somnolence and impair patients ability to drive or operate machinery. Increased seizure frequency or other adverse reactions may occur if pregabalin is rapidly discontinued. Pregabalin should be withdrawn gradually over a minimum of 1 week. Pregabalin may cause peripheral edema. Caution should be exercised when coadministering pregabalin and thiazolidinedione antidiabetic agents.

Pregabalin is unlikely to be involved in significant pharmacokinetic drug interactions.

There are no adequate and well-controlled studies with pregabalin in pregnant women. Pregnant women should be advised of the potential risk to a fetus. Small amounts of pregabalin have been detected in the milk of lactating women. Because of the potential risk of tumorigenicity, breastfeeding is not recommended during treatment with pregabalin.

Use in children and adolescents: Safety and effectiveness in pediatric patients have not been established for the management of neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, neuropathic pain associated with spinal cord injury and fibromyalgia. In case of adjunctive therapy for partial onset seizures, safety and effectiveness in pediatric patients below the age of 1 month have not been established. The safety and effectiveness of pregabalin extended-release tablet in pediatric patients have not been established.

In case of overdose with pregabalin, sign and symptoms are reduced consciousness, depression/anxiety, confusional state, agitation and restlessness. Seizures and heart block have also been reported. There is no specific antidote. If indicated, elimination of unabsorbed drug may be attempted by emesis or gastric lavage; usual precautions should be observed to maintain the airway. General supportive care of the patient is indicated including monitoring of vital signs and observation of the clinical status of the patient.

Keep in a cool & dry place (below 30°C), protected from light & moisture. Keep out of the reach of children.

Postherpetic neuralgia in adults (PHN): The recommended dose of Pregabalin is 75 to 150 mg two times a day or 50 to 100 mg three times a day (150 to 300 mg/day) in patients with creatinine clearance of at least 60 ml/min. Dosing should begin at 75 mg two times a day or 50 mg three times a day (150 mg/day). The dose may be increased to 300 mg/day within 1 week based on efficacy and tolerability. Patients who do not experience sufficient pain relief following 2 to 4 weeks of treatment with 300 mg/day and who are able to tolerate Pregabalin, may be treated with up to 300 mg two times a day or 200 mg three times a day (600 mg/day).

Begin dosing of Pregabalin CR capsule at 165 mg once daily and increase to 330 mg once daily within 1 week based on individual patient response and tolerability. Patients who do not experience sufficient pain relief following 2 to 4 weeks of treatment with 330 mg once daily and who are able to tolerate Pregabalin CR capsule, may be treated with up to 660 mg once daily. In view of the dose-dependent adverse reactions and the higher rate of treatment discontinuation due to adverse reactions, dosing above 330 mg/day should be reserved only for those patients who have on-going pain and are tolerating 330 mg daily. The maximum recommended dose of Pregabalin CR capsule is 660 mg once daily.

Management of fibromyalgia in adults: The recommended dose of Pregabalin is 300 to 450 mg/day. Dosing should begin at 75 mg two times a day (150 mg/day). The dose may be increased to 150 mg two times a day (300 mg/day) within 1 week based on efficacy and tolerability. Patients who do not experience sufficient benefit with 300 mg/day may be further increased to 225 mg two times a day (450 mg/day).

Neuropathic pain associated with spinal cord injury in adults: The recommended dose range of Pregabalin is 150 to 600 mg/day. The recommended starting dose is 75 mg two times a day (150 mg/day). The dose may be increased to 150 mg two times a day (300 mg/day) within 1 week based on efficacy and tolerability. Patients who do not experience sufficient pain relief after 2 to 3 weeks of treatment with 150 mg two times a day and who tolerate Pregabalin may be treated with up to 300 mg two times a day.

Conversion from Pregabalin capsules to Pregabalin CR capsule tablet: When switching from Pregabalin capsules to Pregabalin CR capsule tablet on the day of the switch, instruct patients to take their morning dose of Pregabalin capsule as prescribed and initiate Pregabalin CR capsule therapy after an evening meal.

Pregabalin tablet total daily dose (dosed 2 or 3 times daily): Pregabalin CR capsule capsule dose (dosed once a day)

• 75 mg/daily: 82.5 mg/day
• 150 mg/daily: 165 mg/day
• 225 mg/daily: 247.5 mg/day
• 300 mg/daily: 330 mg/day
• 450 mg/daily: 495 mg/day
• 600 mg/daily: 660 mg/day

Route of administration: Pregabalin is taken in oral route. It can be taken with or without food. Pregabalin CR tablet should be administered after an evening meal. It should be swallowed whole and should not be split, crushed or chewed. If patients miss taking their dose of Pregabalin CR after an evening meal, then they should take their usual dose of Pregabalin CR prior to bedtime following a snack. If they miss taking the dose of Pregabalin CR prior to bedtime, then they should take their usual dose of Pregabalin CR following a morning meal. If they miss taking the dose of Pregabalin CR following the morning meal, then they should take their usual dose of Pregabalin CR at the usual time that evening following an evening meal. When discontinuing both Pregabalin and Pregabalin CR, it should be gradually tapered over a minimum of 1 week.

Most common side effects in adults are dizziness, somnolence, dry mouth, edema, blurred vision, weight gain and thinking abnormal (primarily difficulty with concentration/attention). Most common side effects in pediatric patients for the treatment of partial onset seizures are increased weight and increased appetite.

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

Angioedema (e.g., swelling of the throat, head and neck) can occur and may be associated with life threatening respiratory compromise requiring emergency treatment. Pregabalin should be discontinued immediately in these cases. Pregabalin should also be discontinued immediately if hypersensitivity reactions (e.g., hives, dyspnea and wheezing) occur. Antiepileptic drugs, including pregabalin, increase the risk of suicidal thoughts or behavior. Respiratory depression may occur with pregabalin when used with concomitant CNS depressants or in the setting of underlying respiratory impairment. Patients need to be monitored and dosage adjusted as appropriate. Pregabalin may cause dizziness and somnolence and impair patients ability to drive or operate machinery. Increased seizure frequency or other adverse reactions may occur if pregabalin is rapidly discontinued. Pregabalin should be withdrawn gradually over a minimum of 1 week. Pregabalin may cause peripheral edema. Caution should be exercised when coadministering pregabalin and thiazolidinedione antidiabetic agents.

Pregabalin is unlikely to be involved in significant pharmacokinetic drug interactions.

There are no adequate and well-controlled studies with pregabalin in pregnant women. Pregnant women should be advised of the potential risk to a fetus. Small amounts of pregabalin have been detected in the milk of lactating women. Because of the potential risk of tumorigenicity, breastfeeding is not recommended during treatment with pregabalin.

Use in children and adolescents: Safety and effectiveness in pediatric patients have not been established for the management of neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, neuropathic pain associated with spinal cord injury and fibromyalgia. In case of adjunctive therapy for partial onset seizures, safety and effectiveness in pediatric patients below the age of 1 month have not been established. The safety and effectiveness of pregabalin extended-release tablet in pediatric patients have not been established.

In case of overdose with pregabalin, sign and symptoms are reduced consciousness, depression/anxiety, confusional state, agitation and restlessness. Seizures and heart block have also been reported. There is no specific antidote. If indicated, elimination of unabsorbed drug may be attempted by emesis or gastric lavage; usual precautions should be observed to maintain the airway. General supportive care of the patient is indicated including monitoring of vital signs and observation of the clinical status of the patient.

Keep in a cool & dry place (below 30°C), protected from light & moisture. Keep out of the reach of children.

Adjunct anti-epileptic drugs, Primary anti-epileptic drugs

Pregabalin is a structural derivative of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). It does not bind directly to GABA_A, GABA_B or benzodiazepine receptors. Pregabalin binds with high affinity to the alpha2-delta site (an auxiliary subunit of voltage-gated calcium channels) in central nervous system tissues. Although the mechanism of action of Pregabalin has not been fully elucidated, results in animal studies suggest that binding to the alpha2-delta subunit may be involved in Pregabalin's anti-nociceptive and antiseizure effects.

Neuropathic pain associated with diabetic peripheral neuropathy in adults (DPN): The maximum recommended dose of Pregabalin is 100 mg three times a day (300 mg/day) in patients with creatinine clearance of at least 60 ml/min. Dosing should begin at 50 mg three times a day (150 mg/day). The dose may be increased to 300 mg/day within 1 week based on efficacy and tolerability.

Vitamin-B preparations

Thiamine, in the form of thiamine pyrophosphate, is the coenzyme for decarboxylation of α-ketoglutaric acid. Thiamine deficiency affects the peripheral nervous system, the gastrointestinal tract, and the cardiovascular system. This vitamin is necessary for the optimal growth of infants and children. Thiamine is not stored in the body, and is regularly lost from tissues during short periods of deficiency. In order to maintain normal health, an adequate amount of thiamine is required every day. Deficiency of thiamine leads to fatigue, anorexia, gastrointestinal disturbance, tachycardia, irritability and neurological symptoms. Beriberi, a disease due to vitamin B1 deficiency, is common in alcoholics, in pregnant women receiving an inadequate diet, and in people with malabsorption syndrome, prolonged diarrhoea and hepatic disease.

Thiamine is well absorbed from the gastrointestinal tract and widely distributed throughout the body. Thiamine is rapidly absorbed from the upper small intestine. Thiamine is not stored in the body to any appreciable extent. Excess ingested thiamine appears in urine as intact thiamine or as pyrimidine, which arises from degradation of the thiamine molecule. The plasma half life of thiamine is 24 hours.

Prophylaxis: 3 to 10 mg daily.
Mild chronic deficiency: 10 to 25 mg daily.
Severe deficiency: 200 to 300 mg daily.

Vitamin B1 does not have adverse effects when given orally, but in a few fatal cases anaphylactic reactions have occurred after intravenous administration of large doses (400 mg) in sensitive patients, especially children, and in one case following an intramuscular dose of 125 mg. The risk of such reactions increases with repeated administration of the drug by parenteral route. Transient mild soreness may occur at the site of intramuscular administration

There is no absolute contraindication but the risk of anaphylaxis is increased by repeated parenteral administration. Mild allergic phenomena, such as sneezing or mild asthma are warning signs that further may give rise to anaphylactic shock. To avoid this possibility it is advisable to start a second course of injection with a dose considerably lower than that previously used. Because of the above, vitamin B1 injection should not be given intravenously except in the case of comatose patients. Once thiamine deficiency is corrected there is no need for parenteral administration or for the administration of amounts in excess of daily requirement.

No hazardous drug interactions have been reported. Vitamin B1 acts synergistically with other vitamins of the B-complex group and its potential for causing adverse effects is considerably reduced.

The drug may be given safely to neonates, children, pregnant and lactating women and elderly patients.

Thiamine injection should be protected from light and moisture.

Vitamin B1, B6 & B12 is indicated for the treatment of vitamin B1, B6 & B12 deficiency syndrome. It is also indicated for the supportive treatment of neuritis & non-inflammatory diseases of the nerves, e.g.- Diabetic neuropathy, Peripheral neuralgin, Lumbago, Myalgia, Optic neuritis, Sciatica, Facial neuralgia, Intercostal neuralgia, Spinal pain.

Specific combined vitamin preparations

Vitamin B1 converts carbohydrates, fatty acids and amino acids into energy, promotes healthy nerves, improves mood, strengthens the heart. Vitamin B6 forms RBCs, helps cells to make proteins, manufactures neurotransmitters e.g. serotonin and releases stored forms of energy, helps to prevent CVS diseases and stroke, helps to lift depression and eases insomnia. Vitamin B12 is essential for cell replication and important for RBC production, prevents anemia, helps to prevent depression, reduces nerve pain, numbness, tingling and lowers the risk of heart diseases.

The vitamin ingredients are absorbed well in per oral reception. It is widely distributed to most tissues and appears in breast milk. Within the cell, thiamine is mostly present as diphosphate. Thiamine is not stored to any appreciable extent in the body and amounts in excess of the body’s requirements are excreted in the urine as unchanged thiamine or as metabolites. Pyridoxine, pyridoxal and pyridoxamine are readily absorbed from the GIT following oral administration and are converted to the active forms of pyridoxal phosphate an pyridoxamine phosphate. They are stored mainly in liver where there is oxidation to 4-pyridoxic acid and other inactive metabolites, which are excreted in urine. As the dose increases, proportionally greater amounts are excreted unchanged in the urine.

Tablet: 1-3 Tablets per day or as advised by the physician.

Injection:

• In severe (acute) cases: 1 injection daily until the acute symptoms subside or taken as advised by the physician.
• In mild cases: 1 injection 2-3 times per week. Ampoules are preferably injected intramuscularly.

Use in children: There is no information on the use of this drug in children.

Generally well tolerated but allergic reactions may be observed in few cases.

Vitamin B1, Vitamin B6 and Vitamin B12 is contraindicated in patients on levodopa therapy, and in patients with hypersensitivity to any of the ingredients of the preparation.

Cyanocobalamin should not be given in patients with subacute degeneration of the spinal cord. Cyanocobalamin is not suitable form of vitamin B12 for the treatment of optic neuropathies associated with raised plasma concentrations of cyanocobalamin.

No drug interaction has been reported yet.

Oral tablet form is recommended but due to the presence of benzyl alcohol, injection is not recommended during pregnancy & lactation.

No overdosage symptoms are to be expected in the recommended dosage. If there is known overdose then treatment is symptomatic & supportive.

Keep out of reach of children. Store in a cool (below 25°C temperature) and dry place, protected from light.

Antacids

This is the mixture of non-systemic acid neutralizing substances and antiflatulent. This preparation offers reliability as well as long action. Aluminium Hydroxide and Magnesium Hydroxide induce the relief of ulcer by neutralizing gastric acid secreted from parietal cells of the stomach. The clinical use of simethicone is based on its antifoam properties. Simethicone spreads on the surface of aqueous liquids, forming a film of low surface tension and causing collapse of foam bubbles. Simethicone repeatedly allows mucous surrounded gas bubbles in the GI tract to coalesce and be expelled.

This is used in the treatment of flatulence and meteorism for the elimination of gas, air or foam from the gastro-intestinal tract prior to radiography and for the relief of abdominal distension and dyspepsia.

Simethicone is physiologically inert; it does not appeared to be absorbed from the GI tract to interfere with gastric secretion or absorption of nutrients. Following oral administration, the drug is excreted unchanged in the feces.

Tablet: 1-2 tablets 1-3 hours after meal and at bed time or as directed by the physician.

Suspension: 1-2 teaspoonful 1-3 hours after meal and at bedtime or as directed by the physician.

Gastrointestinal side effects are uncommon. Occasionally, if excessive amount is consumed, diarrhea, constipation or regurgitation may occur.

This should not be administered in patients with renal failure or hypophosphataemia or in those who are severely debilitated. It is also contraindicated in alkalosis and hypermagnesaemia, where abdominal distention may be due to partial or complete intestinal obstruction.

This should be used with caution in patients with kidney disease.

All antacids may increase or decrease the rate and/or extent of absorption of concomitantly administered oral drugs. Antacids decrease the bioavailability of theophyline, tetracycline, quinolone antibiotics, isoniazide, ketoconazole, ethambutol, some antimuscarinic drugs, benzodiazepines, phenothiazines, ranitidine, indomethacine, nitrofurantoin, fluoride, phosphate, propanolol, atenolol, digoxins, vitamins etc. Antacids increase the bioavailability of some drugs; e.g. sulphonamides, levodopa, valproic acid, enteric coated aspirin etc.

It is advised to avoid antacid preparations in the first trimester of pregnancy.

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

The vitamin ingredients are absorbed well in per oral reception. It is widely distributed to most tissues and appears in breast milk. Within the cell, thiamine is mostly present as diphosphate. Thiamine is not stored to any appreciable extent in the body and amounts in excess of the body’s requirements are excreted in the urine as unchanged thiamine or as metabolites. Pyridoxine, pyridoxal and pyridoxamine are readily absorbed from the GIT following oral administration and are converted to the active forms of pyridoxal phosphate an pyridoxamine phosphate. They are stored mainly in liver where there is oxidation to 4-pyridoxic acid and other inactive metabolites, which are excreted in urine. As the dose increases, proportionally greater amounts are excreted unchanged in the urine.
