Diabetes Medication- Increase Risk of Heart Problems

Older patients treated with the diabetes medications known as thiazolidinediones (which include rosiglitazone) had a significantly increased risk of heart attack, congestive heart failure and death, compared with the use of other hypoglycemic drugs, according to a study. The authors suggest that these results provide further evidence that this class of medication may cause more harm than good.

The thiazolidinediones (TZDs) rosiglitazone and pioglitazone are oral hypoglycemic agents used to treat type 2 diabetes and have been shown to improve glycemic control. While improved glycemic control has been linked to better clinical outcomes in diabetes and TZDs have been suggested as having potential cardiovascular benefits, recent concerns have arisen regarding adverse cardiac effects of these drugs.
