Rosiglitazone

About Rosiglitazone
Thiazolidinedione derivative, Oral anti-diabetic.
Mechanism of Action of Rosiglitazone
The drug exerts antidiabetic action by acting as a selective agonist for the nuclear "peroxisome proliferator-activated receptor Gama (PPAR Gama); which enhances the transcription of several insulin responsive genes. It reverses insulin resistance by stimulating GLUT4 (glucose transporter 4) expression and translocation and improves entry of glucose in to muscle and adipose tissue. It also suppresses hepatic gluconeogenesis. Activation of genes regulating fatty acid metabolism and lipogenesis in adipose tissue also contributes to the insulin sensitizing action of drug. It reduces blood glucose and HbA1c; improves glycaemic control and lowers circulating levels of Insulin.

Pharmacokinets of Rosiglitazone
Absorption: Well absorbed orally and bioavailability is about 99%, Distribution: Widely distributed in a highly protein bound form, Metabolism: Extensively metabolized in the body. Primarily metabolized through N-demethylation and hydroxylation; with subsequent conjugation, Excretion: Excreted mainly through urine (64%) and rest is excreted through faeces.

Glimepiride

About Glimepiride
Third-generation sulfonylurea, Oral Antidiabetic Agent.
Mechanism of Action of Glimepiride
It is a potent antidiabetic drug which exerts its 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 stronger 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.
Pharmacokinets of Glimepiride
Absorption: Well absorbed orally
Distribution: Distributed in a highly protein bound form
Metabolism: Completely metabolized in to inactive metabolites in liver
Excretion: Excreted mainly through urine and also through faeces as metabolites.
