Metformin: Its salutary effects beyond diabetes mellitus.

Abstract

Metformin, an oral hypoglycemic agent, is commonly used in patients with type II diabetes mellitus. Studies have shown its use is associated with a reduction in major cardiovascular events (MACE) in patients with type 2 diabetes such as hospitalization for acute myocardial infarction, stroke, transient ischemic attack, or cardiovascular death. There is also a suggestion that metformin may have effects beyond those relating to lowering of blood sugar. The goal of this review is to assess the effects of metformin in coronary artery disease (CAD), but more importantly, its effects on disease states other than CAD.
