The effect of a thiazolidinedione drug, troglitazone, on glycemia in patients with type 2 diabetes mellitus poorly controlled with sulfonylurea and metformin. A multicenter, randomized, double-blind, placebo-controlled trial.

Background: The thiazolidinediones are a new class of antidiabetes medication that enhances the actions of insulin in muscle, liver, and adipose tissue. Data have been lacking on their use in combination with both sulfonylurea and metformin among patients for whom insulin is the usual therapeutic alternative for improved glycemic control.

Objective: To determine the effects of troglitazone on hemoglobin A(1c) level in patients treated with maximum tolerated doses of sulfonylurea and metformin who have hemoglobin A(1c) levels of at least 0.

Troglitazone monotherapy improves glycemic control in patients with type 2 diabetes mellitus: a randomized, controlled study. The Troglitazone Study Group.

To assess the effects of troglitazone monotherapy on glycemic control in patients with type 2 diabetes mellitus, we carried out a 6-month, randomized, double-blind, placebo-controlled study in 24 hospital and outpatient clinics in the United States and Canada. Troglitazone 100, 200, 400, or 600 mg or placebo once daily with breakfast was administered to 402 patients with type 2 diabetes with fasting serum glucose (FSG) > 140 mg/dL, glycosylated hemoglobin (HbA1c) > 6.5%, and fasting C-peptide > or = 1.

Metabolic effects of troglitazone monotherapy in type 2 diabetes mellitus. A randomized, double-blind, placebo-controlled trial.

Background: Troglitazone is a new insulin-sensitizing agent used to treat type 2 diabetes mellitus. The mechanism by which troglitazone exerts its effect on systemic glucose metabolism is unknown.

Objective: To determine the effects of 6 months of troglitazone monotherapy on glucose metabolism in patients with type 2 diabetes mellitus.

Effects of age on the elimination of labetalol.

Labetalol is an alpha 1- and beta-adrenergic antagonist currently used in the treatment of hypertension. Studies which have evaluated the effects of age on its pharmacokinetics have yielded conflicting results. The purpose of this study is to comprehensively re-evaluate the effect of age on the elimination of labetalol.
