NATIONAL HARBOR, Md.--(BUSINESS WIRE)--New data presented at the 61st Annual Scientific Meeting of the Gerontological Society of America showed JANUVIA™ (sitagliptin), a diabetes medicine from Merck & Co., Inc., significantly reduced blood sugar levels in elderly patients with type 2 diabetes and was not associated with hypoglycemia (low blood sugar). In this study of 206 patients aged 65 to 96 years, there were no reports of hypoglycemia in either the JANUVIA or the placebo groups. Advanced age contributes to the risk of hypoglycemia.
