How beneficial are thiazolidinediones for diabetes mellitus?
Abstract
The thiazolidinediones pioglitazone (Actos) and rosiglitazone (Avandia) are effective at lowering fasting plasma glucose (FPG) and glycosylated hemoglobin (Hb A1c) in patients with type 2 diabetes when used either as monotherapy or in combination with sulfonylureas, metformin, or insulin. The glucose-lowering effects appear comparable with those of sulfonylureas and metformin alone. Currently, there are no randomized trials directly comparing patient-oriented outcomes of the thiazolidinediones with those of sulfonylureas and metformin. Grade of recommendation: B (on the basis of extrapolations from randomized trials and low quality randomized trials).
