Recent advances in Sustained Release Drug delivery System (SRDDS) aim to enhance safety and efficacy of drug molecule by formulating a convenient dosage form for administration and to achieve better patient compliance. This present study showed that the Gliclazide is an oral hypoglycemic (anti-diabetic drug) and is classified as a sulfonylurea. Its classification has been ambiguous, as literature used it as both a first generation and second generation sulfonylurea. Gliclazide was shown to protect human pancreatic beta-cells from hypoglycemia-induced apoptosis. It was shown to have an anti-atherogenic effect (preventing accumulation of fat in arteries) in type II diabetes. Gliclazide is used in the tablet form for antidiabetic effect.
