In a randomized, double-blind, placebo-controlled trial recently published in Lancet, the thiazolidinedione (or "glitazone") rosiglitazone statistically significantly reduced the incidence of new-onset diabetes when given to patients diagnosed with prediabetes but lacking a prior history of cardiovascular disease. The benefits of using thiazolidinediones in the treatment of patients with diabetes are well known, but the current finding that thiazolidinediones can prevent prediabetics from progressing to diabetes is novel.
