Gilatavis
Gilatavis Uses, Dosage, Side Effects, Food Interaction and all others data.
Gilatavis stimulates the release of insulin from pancreatic beta-cells by facilitating Ca++ transport across the beta-cell membranes. It lowers blood glucose by stimulating the release of insulin from the pancreas, an effect dependent upon functioning beta cells in the pancreatic islets. Extrapancreatic effects also may play a part in the mechanism of action of oral sulfonylurea hypoglycemic drugs. Two extrapancreatic effects shown to be important in the action of Gilatavis are an increase in insulin sensitivity and a decrease in hepatic glucose production. The anti-oxidant, platelet inhibiting and fibrinolytic actions of Gilatavis involve processes which have been implicated in the pathogenesis of vascular complications of type 2 diabetes.
Based on the pharmacological properties, gliclazide is a second generation sulphonylurea which acts as a hypoglycemic agent. It stimulates β cells of the islet of Langerhans in the pancreas to release insulin. It also enhances peripheral insulin sensitivity. Overall, it potentiates insulin release and improves insulin dynamics.

Uses
Gilatavis is used for control of blood glucose in patients with non-insulin dependent diabetes mellitus (Type-II, maturity onset diabetes mellitus) whose hyperglycemia cannot be controlled by diet alone.
Gilatavis is also used to associated treatment for these conditions: Type 2 Diabetes Mellitus
How Gilatavis works
Gilatavis binds to the β cell sulfonyl urea receptor (SUR1). This binding subsequently blocks the ATP sensitive potassium channels. The binding results in closure of the channels and leads to a resulting decrease in potassium efflux leads to depolarization of the β cells. This opens voltage-dependent calcium channels in the β cell resulting in calmodulin activation, which in turn leads to exocytosis of insulin containing secretorty granules.
Dosage
Gilatavis dosage
Adult: The usual initial dose of Gilatavisis 40 to 80 mg daily, gradually increased, if necessary up to 320 mg daily until adequate control is achieved. A single dose should not exceed 160 mg. When higher doses are required it should be taken twice daily, according to the main meals of the day. For extended release tablet the initial recommended dose is 30 mg daily, even in elderly patients (>65 years); the daily dose may vary from 30 to 120 mg taken orally, once daily.
Gilatavis extend release tablet should be taken with food because there is increased risk of hypoglycemia if a meal is taken late. It is recommended that the medication be taken at breakfast time. If a dose is forgotten, the dose taken on the next day should not be increased. Dose titration should be carried out in steps of 30 mg, according to the fasting blood glucose response. Each step should last for at least two weeks. Gilatavis extend release tabletshould be neither broken nor chewed. Gilatavis extend release tablet30 mg, can replace Gilatavis 80 mg tabletsfor doses of 1 to 4 tablets per day.
Elderly: Plasma clearance of Gilatavis is not altered in the elderly and steady state plasma levels are similar to those in adults under 65 years. Clinical experience in the elderly shows that it is effective and well tolerated.
Children: Gilatavis as with other sulfonylureas is not indicated for the treatment of juvenile onset diabetes mellitus.
Side Effects
Hypoglycemia may occur in concurrent conditions such as hepatic & renal diseases, alcohol intoxication and adrenal and pituitary insufficiency. Mild gastro-intestinal disturbances including nausea, dyspepsia, diarrhea, and constipation have been reported but these types of adverse reactions can be avoided if Gilatavis is taken during a meal. Allergic dermatological reactions including rash, prurits, erythema, bullous eruption have been reported during treatment with the drug but are not known to be directly attributable to it. More serious reactions like leucopenia, thrombocytopenia, agranulocytosis, pancytopenia, hemolytic anemia, cholestatic jaundice, GI hemorrhage have not been reported with Gilatavis.
Toxicity
LD50=3000 mg/kg (orally in mice). Gilatavis and its metabolites may accumulate in those with severe hepatic and/or renal dysfunction. Symptoms of hypoglycemia include: dizziness, lack of energy, drowsiness, headache and sweating.
Precaution
Gilatavis should be used carefully in patients with hepatic impairment. If there is definite hepatic disease then gliclazide should not be used. Consucon (Gilatavis) can be used safely in patients with renal insufficiency as it is extensively metabolized. Consucon has less sudden hypoglycaemic episode than other sulfonylurea group of drugs.
Interaction
The hypoglycemic effect of Gilatavis may be potentiated by NSAID (in particular aspirin), phenylbutazone, sulfonamides, coumarin derivatives, MAOIs, beta-adrenergic blockers, tetracyclines, chloramphenicol, clofibrate, cimetidine and miconazole tablets. Ingestion of alcohol may also increase the hypoglycemic effect of Gilatavis. Some drugs may on the contrary, reduce its activity e.g. barbiturates, corticosteroides, thiazide diuretics, thyroid hormones, laxatives and oral contraceptives.
Food Interaction
- Avoid alcohol.
- Take with or without food. Consistent food intake reduces the risk of hypoglycemia.
Elimination Route
Rapidly and well absorbed but may have wide inter- and intra-individual variability. Peak plasma concentrations occur within 4-6 hours of oral administration.
Half Life
10.4 hours. Duration of action is 10-24 hours.
Elimination Route
Metabolites and conjugates are eliminated primarily by the kidneys (60-70%) and also in the feces (10-20%).
Pregnancy & Breastfeeding use
Pregnant Women: Gilatavis should not be used in pregnant women although animal studies of Gilatavis have not shown any teratogenic effect.
Nursing Mothers: This drug is contraindicated when breast feeding.
Contraindication
Hypersensitivity to sulfonylurea, diabetes complicated by ketoacidosis with coma, as a sole therapy of insulin-dependent (Type-1) diabetes mellitus, diabetes when complicated by pregnancy & breast-feeding.
Special Warning
Elderly: Plasma clearance of Gilatavis is not altered in the elderly and steady state plasma levels are similar to those in adults under 65 years. Clinical experience in the elderly shows that it is effective and well tolerated.
Children: Gilatavis as with other sulfonylureas is not indicated for the treatment of juvenile onset diabetes mellitus.
Acute Overdose
Symptoms: Hypoglycaemia with or without coma, convulsions or other neurological disorders.
Management: Carbohydrate intake, dosage adjustment and/or change of diet may be helpful. Admin rapid IV inj of concentrated glucose soln for hypoglycaemic coma.
Storage Condition
Store in a cool and dry place, below 30° C and away from light.
