Study to Estimate the Effects of Inhaled Versus Intravenous (IV) Infusion of Human Insulin in Subjects With Type 1 Diabetes

Completed · Phase 4

Conditions studied: Type 1 Diabetes Mellitus

In brief

University of Pittsburgh Medical Center (UPMC) diabetes research physicians are studying the action in muscle tissue of "inhaled" insulin (Exubera®) and "infused" (intravenous or IV) insulin on blood sugar control in people with type 1 diabetes. Type 1 diabetics often take 2-4 shots of insulin every day. Exubera may offer an alternative to these insulin injections.
