- Pharmacology For Gliclazide
GliclazideAbout GliclazideFirst generation Sulfonylurea, Oral Antidiabetic Agent.Mechanism of Action of GliclazideIt is an antidiabetic drug which exerts it`s action by increasing insulin release from the pancreas and by improving glucose tolerance. It acts on the "sulfonylurea receptors" on pancreatic ?-cell membrane and reduces conductance of ATP sensitive K+ channels and thus causes depolarization. This enhances Ca2+ influx and degranultion and thus increases insulin secretion rate at any glucose concentration. It primarily increases 2nd phase insulin secretion and has little effect on 1st phase. It also slows hepatic degradation of insulin and minor action of reducing glucagon release and increasing Somatostatin release. It also exerts extrapancreatic action; by sensitizing the target tissues such as liver to insulin action. It increases the number of insulin receptors and through a post receptor action improving translation of receptor activation. It also possesses anti-platelet action and also reduces free radicals.Pharmacokinets of GliclazideAbsorption: Well absorbed orally.

Hypoglycemic effect of gliclazide inhibited by the following drugs: b-blockers, Cholestyramine, Diazoxide, Hydantoins, Rifampicin, Thiazide diuretics & Urinary alkalisers.
Charcoal: Reduces the absorption of gliclazide thus reducing its efficacy or toxicity.
Digitalis glycosides: Co-administration results in increased digitalis serum levels.
Typical Dosage for Gliclazide80mg twice daily. Adjust the dosage up to 160mg twice daily based on patient`s response if required. Schedule of GliclazideHStorage Requirements for GliclazideStore at room temperature at a range of 15 to 30 degree C.in a well closed container away fro light. Protect from excess heat and moisture. Keep out of reach of children.Effects of Missed Dosage of GliclazideTake the missed dose as soon as noticed and if it is the time for next dose then skip the missed dose. Continue the regular schedule. Do not double the dose.Effects of Overdose of GliclazideMild hypoglycemia can be treated with oral glucose and dosage adjustment. If there is loss of consciousness or neurological findings the patient should receive rapid injection of dextrose 50%; followed by continuous infusion of dextrose 10% at a rate to maintain blood glucose levels greater than 100mg/dl. Monitor patient for 24 to 48 hours.
