The type 2 diabetes drug metformin is safer for the heart than other older diabetes medication, according to a two-year study. The findings are important because older patients with diabetes are at particular risk for cardiovascular disease, and because many of them are prescribed a class of diabetes medications called sulfonylureas that may raise this risk.
The controversial diabetes drug Avandia, which has been linked to heart problems, is a sulfonylureas diabetes drug. Sulfonylureas have also been linked to episodes of low blood sugar, and to weight gain.
Sulfonylureas drugs and metformin (also known by the brand name Glucophage) lower blood sugar in different ways. Metformin works by suppressing sugar production in the liver, while sulfonylureas work by increasing insulin production. To read more about the study findings on WebMD, >CLICK HERE.<
