THURSDAY, April 7 (HealthDay News) -- The commonly used oral diabetes drug metformin not only helps stabilize blood sugar levels, it also may offer protection against heart disease, researchers say. In a study that included more than 100,000 residents of Denmark taking metformin or another group of oral diabetes medications called insulin secretagogues (ISs), researchers found that metformin and the IS drugs gliclazide and repaglinide had the lowest risk of cardiovascular disease and death.
