Liver Enzyme Monitoring in Patients Treated With Troglitazone

Abstract
Troglitazone is a thiazolidinedione antidiabetic agent that decreases insulin resistance. It was approved by the US Food and Drug Administration (FDA) in January 1997 for treatment of type 2 diabetes mellitus. During premarketing clinical trials, serum liver transaminase elevations exceeding 3 times the upper limit of normal were observed in 1.9% of troglitazone-treated patients vs 0.6% in comparators.1 Of 2510 patients treated with troglitazone in these trials, 2 were hospitalized with drug-associated hepatitis and 2 developed jaundice.
