Avandia

Rosiglitazone is an anti-diabetic drug from the thiazolidinedione class. It is being marketed as Avandia® by the pharmaceutical company GlaxoSmithKline, both as a standalone preparation and in combination with metformin (Avandamet®). Another combination drug approved by the FDA is Avandaryl® (with glimepiride). more...

Like other thiazolidinediones, its mechanism of action is by activation of the intracellular receptor class of the peroxisome proliferator-activated receptors (PPARs), specifically PPARγ. Rosiglitazone is a pure ligand of PPARγ, and has no PPARα-binding action. Apart from its effect on insulin resistance, it appears to have an anti-inflammatory effect: nuclear factor kappa-B (NFκB) levels fall and inhibitor (IκB) levels increase in patients on rosiglitazone (Mohanty et al).
