Gliclazide
GL-80
Gliclazide
Indications
Type 2 DM
Indication detailsView
Gliclazide is a medicine that reduces blood sugar levels (oral antidiabetic medicine belonging to the sulphonylurea group). Gliclazide is used in a certain form of diabetes (type 2 diabetes Mellitus) in adults, when diet, exercise and weight loss alone do not have an adequate effect on keeping blood sugar at the correct level.
Therapeutic classView
Sulfonylureas
PharmacologyView
Gliclazide is a second generation sulfonylurea drug that has hypoglycaemic and potentially useful hematological properties. It stimulates the release of insulin from pancreatic β-cells by facilitating Ca+2 transport across the β-cell membranes and decreases hepatic glucose output.
DosageView
Film-coated tablet: The usual initial dose is 40 to 80 mg daily. The dose can be increased up to 320 mg daily in divided doses when needed. The drug should be taken before meal. For children, Gliclazide is not used because it is contraindicated in juvenile-onset diabetes.
Modified release preparation: Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. The dose is determined by the doctor, depending on your blood and possibly urine sugar levels. Change in external factors (weight reduction, lifestyle, stress) or improvements in the blood sugar control may require changed gliclazide doses.
The recommended daily dose is one to four tablets (maximum 120 mg) in a single intake at breakfast time. This depends on the response to treatment. Gliclazide MR tablet is for oral use. Take your tablet(s) with a glass of water at breakfast time (and preferably at the same time each day). Swallow your whole tablet(s) in one piece. Do not chew or crush. You must always eat a meal after taking your tablet(s).
If a combination therapy of gliclazide with metformin, an alpha-glucosidase inhibitor, a thiazolidinedione, a dipeptidyl peptidase-4 inhibitor a GLP-1 receptor agonist or insulin is initiated your doctor will determine the proper dose of each medicine individually for you. If you notice that your blood sugar levels are high although you are taking the medicine as prescribed, you should contact your doctor or pharmacist.
If you take more Gliclazide tablets than you should: If you take too many tablets, contact your doctor or the nearest hospital Accident & Emergency department immediately. The signs of overdose are those of low blood sugar (hypoglycaemia). The symptoms can be helped by taking sugar (4 to 6 lumps) or sugary drinks straight away, followed by a substantial snack or meal. If the patient is unconscious immediately inform a doctor and call the emergency services. The same should be done if somebody, (for instance a child), has taken the product unintentionally. Unconscious patients must not be given food or drink. It should be ensured that there is always a pre-informed person that can call a doctor in case of emergency.
If you forget to take Gliclazide tablet: It is important to take your medicine every day as regular treatment works better. However, if you forget to take a dose of Gliclazide MR tablet, take the next dose at the usual time. Do not take a double dose to make up for a forgotten dose.
If you stop taking Gliclazide MR tablet: As the treatment for diabetes is usually lifelong, you should discuss with your doctor before stopping this medicinal product. Stopping could cause high blood sugar (hyperglycaemia) which increases the risk of developing complications of diabetes. If you have any further questions on the use of this product, ask your doctor or pharmacist.

Side effectsView
Like all medicines, Gliclazide can cause side effects, although not everybody gets them. The most commonly observed side effect is low blood sugar (hypoglycaemia). If left untreated these symptoms could progress to drowsiness, loss of consciousness or possibly coma. If an episode of low blood sugar is severe or prolonged, even if it is temporarily controlled by eating sugar, you should seek immediate medical attention.
Liver disorders: There have been isolated reports of abnormal iiver function, which can cause yellow skin and eyes. If you get this, see your doctor immediately. The symptoms generally disappear if the medicine is stopped. Your doctor will decide whether to stop your treatment.
Skin disorders: Skin reactions such as rash, redness, itching, hives, blisters, angioedema (rapid swelling of tissues such as eyelids, face, lips, mouth, tongue or throat that may result in breathing difficulty) have been reported. Rash may progress to widespread blistering or peeling of the skin. If you develop this, stop taking, seek urgent advice from a doctor and tell him that you are taking this medicine. Exceptionally, signs of severe hypersensitivity reactions have been reported: initially as flu-like symptoms and a rash on the face then an extended rash with a high temperature.
Blood disorders: Decrease in the number of cells in the blood (e.g. platelets, red and white blood cells) which may cause paleness, prolonged bleeding, bruising, sore throat and fever have been reported. These symptoms usually vanish when the treatment is discontinued.
Digestive disorders: Abdominal pain, nausea, vomiting, indigestion, diarrhoea, and constipation. These effects are reduced when Gliclazide is taken with a meal as recommended.
Eye disorders: Your vision may be affected for a short time especially at the start of treatment. This effect is due to changes in blood sugar levels.
As for another sulfonylurea, the following adverse events have been observed: cases of severe changes in the number of blood cells and allergic inflammation of the wall of blood vessels, reduction in blood sodium (hyponatraemia), symptoms of liver impairment (for instance jaundice) which in most cases disappeared after withdrawal of the sulfonylurea, but may lead to life-threatening liver failure in isolated cases.
Reporting of side effects: If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet. By reporting side effects, you can help provide more information on the safety of this medicine.

ContraindicationsView
Do not take Gliclazide:
- if you are allergic to gliclazide or to other medicines of the same group (sulfonylurea), or to other related medicines (hypoglycaemic sulfonamides)
- if you have insulin-dependent diabetes (type 1)
- if you have ketone bodies and sugar in your urine (this may mean you have diabetic ketoacidosis), a diabetic pre-coma or coma
- if you have severe kidney or liver disease
- if you are taking medicines to treat fungal infections
- if you are breastfeeding
PrecautionsView
Talk to your doctor before taking Gliclazide. You should observe the treatment plan prescribed by your doctor to achieve proper blood sugar levels. This means, apart from regular tablet intake, to observe the dietary regimen, have physical exercise and, where necessary, reduce weight During gliclazide treatment regular monitoring of your blood (and possibly urine) sugar level and also your glycated haemoglobin (HbA1c) is necessary. In the first few weeks of treatment, the risk of having reduced blood sugar levels (hypoglycaemia) may be increased. So particularly close medical monitoring is necessary.
Low blood sugar (Hypoglycaemia) may occur:
The following signs and symptoms may also occur: sweating, clammy skin, anxiety, fast or irregular heartbeat, high blood pressure, sudden strong pain in the chest that may radiate into nearby areas (angina pectoris).
If blood sugar levels continue to drop you may suffer from considerable confusion (delirium), develop convulsions, lose self-control, your breathing may be shallow and your heartbeat slowed down, you may become unconscious.
In most cases the symptoms of low blood sugar vanish very quickly when you consume .some form of sugar, (for instance, glucose tablets, sugar cubes, sweet juice, sweetened tea).
You should therefore always carry some form of sugar with you (glucose tablets, sugar cubes). Remember that artificial sweeteners are not effective. Please contact your doctor or the nearest hospital if taking sugar does not help or if the symptoms recur.
Symptoms of low blood sugar may be absent, less obvious or develop very slowly or you are not aware in time that your blood sugar level has dropped. This may happen if you are an elderly patient taking certain medicines (for instance those acting on the central nervous system and beta-blockers).
If you are in stressful situations (e.g. accidents, surgical operations, fever etc.) your doctor may temporarily switch you to insulin therapy.
Symptoms of high blood sugar (hyperglycaemia) may occur when gliclazide has not yet sufficiently reduced the blood sugar when you have not complied with the treatment plan prescribed by your doctor if you take St. John’s Wort (Hypericum perforatum) preparations or in special stress situations. These may include thirst, frequent urination, dry mouth, dry itchy skin, skin infections and reduced performance.
Blood glucose disturbances (low blood sugar and high bold sugar) can occur when Gliclazide is prescribed at the same time as medicines to a class of antibiotics called fluoroquinolone, especially in elderly patients. In this case, your doctor will remind you of the importance of monitoring your blood glucose.
If you have a family history of or know you have the hereditary condition glucose-6-phosphate dehydrogenase (G6PD) deficiency (abnormality of red blood cells), lowering of the haemoglobin level and breakdown of red blood cells (haemolytic anaemia) can occur. Contact your doctor before taking this medicinal product.
Gliclazide is not recommended for use in children due to lack of data.
Low blood sugar (Hypoglycaemia) may occur:
- if you take meals irregularly or skip meals altogether,
- if you are fasting
- if you are malnourished
- if you change your diet
- if you increase your physical activity and carbohydrate intake does not match this increase,
- if you drink alcohol, especially in combination with skipped meals,
- if you take other medicines or natural remedies at the same time,
- if you take too high doses of gliclazide,
- if you suffer from particular hormone-induced disorders (functional disorders of the thyroid gland, pituitary gland or adrenal cortex),
- if your kidney function or liver function is severely decreased.
The following signs and symptoms may also occur: sweating, clammy skin, anxiety, fast or irregular heartbeat, high blood pressure, sudden strong pain in the chest that may radiate into nearby areas (angina pectoris).

GOL
Macrogol [Polypropylene glycol] + Electrolytes
GOL
Macrogol [Polypropylene glycol] + Electrolytes
Indications
Faecal impaction
Indication detailsView
For use in adults and children over 12 years of age for effective relief from constipation and treatment of chronic constipation. Also effective in resolving faecal impaction, defined as refractory constipation with faecal loading of the rectum and colon.
Therapeutic classView
Osmotic purgatives
PharmacologyView
Macrogol (3350) exerts an osmotic action in the gut, which induces a laxative effect. Macrogol (3350) increases the stool volume, which triggers colon motility via neuromuscular pathways. The physiological consequence is an improved propulsive colonic transportation of the soften stools and a facilitation of the defecation. Electrolytes combined with Macrogol (3350) are exchanged across the intestinal barrier (mucosa) with serum electrolytes and excreted without net gain or loss of sodium, potassium and water. Macrogol (3350) is unchanged along the gut. It is virtually unabsorbed from the gastrointestinal tract.
DosageView
Measure 25 ml of this oral solution with the measuring cup provided, then add this to 100 ml of water. Any unused diluted solution should be discarded within 24 hours.
Adult:
Adult:
- Constipation: 25 ml of this oral solution added to 100 ml of water once daily (to make a total volume of 125 ml). This may be increased to 2 - 3 doses of 25 ml daily (each 25 ml dose added to 100 ml of water), if required according to individual response.
- Fecal Impaction: 8 doses of 25 ml daily (each 25 ml dose added to 100 ml of water). A course of treatment for fecal impaction does not normally exceed 3 days.
Side effectsView
In the treatment of chronic constipation, diarrhoea or loose stools normally respond to a reduction in dose. Diarrhoea, abdominal distension, anorectal discomfort and mild vomiting are more often observed during the treatment for fecal impaction. Vomiting may be resolved if the dose is reduced or delayed.
ContraindicationsView
Intestinal perforation or obstruction due to structural or functional disorder of the gut wall, ileus, severe inflammatory conditions of the intestinal tract, such as Crohn's disease and ulcerative colitis and toxic megacolon. Hypersensitivity to the active substances.
PrecautionsView
This medicinal product contains 8.125 mmol of sodium in each dose of 125 ml. The sodium content of this oral solution should be taken into consideration when administering the product to patients on a controlled sodium diet.
InteractionsView
There is a possibility that the absorption of other medicinal products could be transiently reduced during use with this oral solution. There have been isolated reports of decreased efficacy with some concomitantly administered medicinal products, e.g. anti-epileptics.
Pregnancy & lactationView
Clinically, no effects during pregnancy are anticipated, since systemic exposure to Macrogol (3350) is negligible. This oral solution can be used during pregnancy. No effects on the breastfed newborn/infant are anticipated since the systemic exposure of the breast-feeding woman to Macrogol (3350) is negligible. This oral solution can be used during breast-feeding.
Overdose effectsView
Extensive fluid loss by diarrhea or vomiting may require correction of electrolyte disturbances.
StorageView
Store below 30° C and in a place protected from light. Do not refrigerate.

GTN
Nitroglycerin (Sublingual Spray)
GTN
Nitroglycerin (Sublingual Spray)
Indications
Angina pectoris
Indication detailsView
Nitroglycerin sublingual spray is indicated for acute relief of an attack or prophylaxis of angina pectoris due to coronary artery disease.
Therapeutic classView
Nitrates: Coronary vasodilators
PharmacologyView
The principal pharmacological action of nitroglycerin is relaxation of vascular smooth muscle, producing a vasodilator effect on both peripheral arteries and veins with more prominent effects on the latter. Dilation of the post-capillary vessels, including large veins, promotes peripheral pooling of blood and decreases venous return to the heart, thereby reducing left ventricular enddiastolic pressure (pre-load). Arteriolar relaxation reduces systemic vascular resistance and arterial pressure (after-load).
DosageView
At the onset of an attack, 1 or 2 metered sprays should be administered under the tongue. No more than 3 metered sprays are recommended within a 15 minute period. If the chest pain persists, prompt medical attention is recommended. Nitroglycerin spray may be used prophylactically 5 to 10 minutes prior to engaging in activities which might precipitate an acute attack.
Side effectsView
A number of nitrate related adverse effects may occur including headache, facial flushing, dizziness, nausea, vomiting, feelings of weakness, postural hypotension and reflex tachycardia .
ContraindicationsView
Hypersensitivity to nitrates or any constituents of the formulation. Hypotension, hypovolaemia, severe anaemia, cerebral haemorrhage and brain trauma, mitral stenosis and angina caused by hypertrophic obstructive cardiomyopathy. Concomitant administration of phosphodiesterase inhibitors used for the treatment of erectile dysfunction.
PrecautionsView
The use of Nitroglycerin during the early days of acute myocardial infarction requires particular attention to monitoring hemodynamics and clinical status. Nitroglycerin should be used with caution in patients with severely impaired renal or hepatic function, hypothyroidism, malnutrition or hypothermia.
InteractionsView
Use of alcohol with Nitroglycerin may produce severe hypotension and collapse. Oral Nitroglycerin may enhance the bioavailability of dihydroergotamine. Orthostatic hypotension may occur with the combined use of calcium channel blocker, phenothiazines and tricyclic antidepressants.
Pregnancy & lactationView
Pregnancy Category C. There are no adequate and well controlled studies in pregnant women. Nitroglycerin should be given to pregnant women only if clearly needed. It is not known whether nitroglycerin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Nitroglycerin spray is administered to a nursing woman.
Pediatric usageView
Safety and effectiveness of nitroglycerin in pediatric patients have not been established.
Overdose effectsView
Nitrate overdosage may result in: severe hypotension, persistent throbbing headache, vertigo, palpitation, visual disturbance, flushing and perspiring skin (later becoming cold and cyanotic), nausea and vomiting (possibly with colic and even bloody diarrhea), syncope (especially in the upright posture), methemoglobinemia with cyanosis and anorexia, initial hyperpnea, dyspnea and slow breathing, slow pulse, heart block, increased intracranial pressure with cerebral symptoms of confusion and moderate fever, paralysis and coma followed by clonic convulsions and possibly death due to circulatory collapse.
Methemoglobinemia: Case reports of clinically significant methemoglobinemia are rare at conventional doses of organic nitrates. The formation of methemoglobin is dose-related and in the case of genetic abnormalities of hemoglobin that favor methemoglobin formation, even conventional doses of organic nitrates could produce harmful concentrations of methemoglobin.
Treatment of Overdosage: Keep the patient recumbent in a shock position and comfortably warm. Passive movement of the extremities may aid venous return. Administer oxygen and artificial ventilation, if necessary. If methemoglobinemia is present, administration of methylene blue (1% solution), 1-2 mg per kilogram of body weight intravenously, may be required. If an excessive quantity of Nitroglycerin spray has been recently swallowed, gastric lavage may be of use.

GTN SR
Nitroglycerin (Oral preparation)
GTN SR
Nitroglycerin (Oral preparation)
Indications
Severe hypertension
Indication detailsView
Nitroglycerin is indicated for the prophylaxis of angina pectoris. The onset of action is not sufficiently rapid for this form to be useful in aborting an acute anginal episode.
Therapeutic classView
Nitrates: Coronary vasodilators
PharmacologyView
Nitroglycerin causes relaxation of vascular smooth muscle, producing a vasodilator effect on both peripheral arteries and veins. Dilation of veins promote peripheral pooling of blood and decreases venous return to the heart, thereby reducing left ventricular end-diastolic pressure (preload) and relaxation of arteries reduce systemic vascular resistance and arterial pressure (afterload).
DosageView
Dosage should always to be adjusted according to the requirement and response obtained by the individual patient and the severity of the anginal pain. For adults, one Nitroglycerin 2.6 mg sustained released tablet or capsule in morning and evening. This should be taken empty stomach.
Side effectsView
Headache may occur at the onset of treatment but will usually subside after a few days. If the headache persists dosage should be decreased. Other side effects include tachycardia, postural hypotension and syncope, cyanosis and methaemoglobinaemia.
ContraindicationsView
Nitroglycerin is contraindicated in patients with a known hypersensitivity to nitroglycerin, other organic nitrates, or nitrites or to the excipients of the medicine. It is also contraindicated in patients with acute myocardial infarction, marked anaemia, head trauma, cerebral haemorrhage, or closed angle glaucoma.
PrecautionsView
Nitroglycerin should be used with caution in patients who are predisposed to closed-angle glaucoma. As with other drugs for the treatment of angina pectoris, abrupt discontinuation of therapy may lead to exacerbation of symptoms. When discontinuing long term treatment, the dosage should be reduced gradually over several days, and the patient carefully monitored. The use of nitroglycerin during the early days of acute myocardial infarction requires particular attention to hemodynamic monitoring and clinical status to avoid the hazards of hypotension and tachycardia.
InteractionsView
Nitroglycerin dilates peripheral blood vessels and may increase the antihypertensive properties of vasodilators, calcium antagonists, beta-adrenergic blockers. Concomitant use of nitrates with tricyclic antidepressants and alcohol may cause high blood pressure. Concomitant use of nitrates with phosphodiesterase type 5 (PDE5) inhibitors, such as sildenafil, vardenafil and tadalafil cause fall in blood pressure. Aspirin decreases the clearance and enhances the hemodynamic effects of nitroglycerin. Nitroglycerin may reduce the pharmacologic effects of heparin when used concomitantly. Nitrates increase the bioavailability of dihydroergotamine.
Pregnancy & lactationView
Nitroglycerin should not be used during pregnancy or lactation unless considered essential by the physician.

Gabapentin
Indications
Trigeminal neuralgia
Indication detailsView
Gabapentin is indicated for-
- Neuropathic Pain.
- Adjunctive therapy in partial seizure and secondary generalized seizure.
Therapeutic classView
Adjunct anti-epileptic drugs
PharmacologyView
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.
DosageView
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:
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.
AdministrationView
Gabapentin can be taken orally with or without food.
Side effectsView
Fatigue, Dizziness, ataxia, weight gain, peripheral edema, dry mouth and somnolence may occur.
ContraindicationsView
Gabapentin is contraindicated in patients who have known hypersensitivity to the drug.
PrecautionsView
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.
InteractionsView
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 & lactationView
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.
Pediatric usageView
In case of renal impaired patients Gabapentin doses must be reduced.
StorageView
Store below 25°C temperature. Protect from light and moisture. Keep all the medicines out of the reach of the children.

Pregabalin
Indication detailsView
Pregabalin is indicated for:
- Neuropathic pain associated with diabetic peripheral neuropathy (DPN)
- Postherpetic neuralgia (PHN)
- Adjunctive therapy for the treatment of partial-onset seizures in patients 1 month of age and older
- Fibromyalgia
- Neuropathic pain associated with spinal cord injury
- Neuropathic pain associated with diabetic peripheral neuropathy (DPN)
- Postherpetic neuralgia (PHN)
Therapeutic classView
Adjunct anti-epileptic drugs, Primary anti-epileptic drugs
PharmacologyView
Pregabalin is a structural derivative of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). It does not bind directly to GABAA, GABAB 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.
DosageView
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.

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.
Side effectsView
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.
ContraindicationsView
Pregabalin is contraindicated in patients with known hypersensitivity to Pregabalin or any of its components.
PrecautionsView
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.
InteractionsView
Pregabalin is unlikely to be involved in significant pharmacokinetic drug interactions.
Pregnancy & lactationView
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.
Pediatric usageView
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.
Overdose effectsView
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.

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
AdministrationView
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.
Side effectsView
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.
ContraindicationsView
Pregabalin is contraindicated in patients with known hypersensitivity to Pregabalin or any of its components.
PrecautionsView
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.
InteractionsView
Pregabalin is unlikely to be involved in significant pharmacokinetic drug interactions.
Pregnancy & lactationView
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.
Pediatric usageView
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.
Overdose effectsView
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.
StorageView
Keep in a cool & dry place (below 30°C), protected from light & moisture. Keep out of the reach of children.

PharmacologyView
Pregabalin is a structural derivative of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). It does not bind directly to GABAA, GABAB 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.

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.
Side effectsView
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.
ContraindicationsView
Pregabalin is contraindicated in patients with known hypersensitivity to Pregabalin or any of its components.
PrecautionsView
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.
InteractionsView
Pregabalin is unlikely to be involved in significant pharmacokinetic drug interactions.
Pregnancy & lactationView
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.
Pediatric usageView
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.
Overdose effectsView
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.
StorageView

Indications
Trigeminal neuralgia
Indication detailsView
Gabapentin is indicated for-
- Neuropathic Pain.
- Adjunctive therapy in partial seizure and secondary generalized seizure.
Therapeutic classView
Adjunct anti-epileptic drugs
PharmacologyView
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.
DosageView
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:
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.
AdministrationView
Gabapentin can be taken orally with or without food.
Side effectsView
Fatigue, Dizziness, ataxia, weight gain, peripheral edema, dry mouth and somnolence may occur.
ContraindicationsView
Gabapentin is contraindicated in patients who have known hypersensitivity to the drug.
PrecautionsView
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.
InteractionsView
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 & lactationView
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.
Pediatric usageView
In case of renal impaired patients Gabapentin doses must be reduced.

PharmacologyView
Pregabalin is a structural derivative of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). It does not bind directly to GABAA, GABAB 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.

- 450 mg/daily: 495 mg/day
- 600 mg/daily: 660 mg/day
AdministrationView
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.
Side effectsView
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.
ContraindicationsView
Pregabalin is contraindicated in patients with known hypersensitivity to Pregabalin or any of its components.
PrecautionsView
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.
InteractionsView
Pregabalin is unlikely to be involved in significant pharmacokinetic drug interactions.
Pregnancy & lactationView
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.
Pediatric usageView
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.
Overdose effectsView
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.
StorageView

PharmacologyView
Pregabalin is a structural derivative of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). It does not bind directly to GABAA, GABAB 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.

Indications
Trigeminal neuralgia
Indication detailsView
Gabapentin is indicated for-
- Neuropathic Pain.
- Adjunctive therapy in partial seizure and secondary generalized seizure.
Therapeutic classView
Adjunct anti-epileptic drugs
PharmacologyView
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.
DosageView
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).
