In a large clinical trial that directly compared four drugs commonly used to treat type 2 diabetes, researchers found that insulin glargine and liraglutide performed the best of four medications approved by the U.S. Food and Drug Administration to maintain blood glucose levels in the recommended range. Blood glucose management is a key component of keeping people with type 2 diabetes healthy. All four medications evaluated were added to treatment with metformin, which is the first-line drug to treat type 2 diabetes. The trial was funded by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the National Institutes of Health.
More than 37 million Americans have diabetes, and approximately 90 to 95% of them have type 2 diabetes. People with diabetes who keep their blood glucose levels in the near-normal range generally have a much lower risk of developing diabetes complications such as nerve, kidney, and eye diseases. Most people with type 2 diabetes require more than one medication to control blood sugar levels over time.
While there is general agreement among health care professionals that metformin combined with diet and exercise is the best early approach in diabetes care, there is no consensus on what to do next to best keep high blood glucose in check.
