Combination therapy for patients with uncontrolled type 2 diabetes mellitus: adding empagliflozin to pioglitazone or pioglitazone plus metformin
Abstract
INTRODUCTION: For patients with type 2 diabetes mellitus (T2DM), there is a growing interest in sodium glucose co-transporter 2 (SGLT2) inhibitors, a class of glucose-lowering agents that act independently of insulin secretion and insulin action and also have a weight-lowering effect. Empagliflozin is an SGLT2 inhibitor that has been demonstrated to significantly reduce blood glucose levels and is well tolerated in patients with T2DM.
AREAS COVERED: Kovacs et al. have reported a randomized, placebo-controlled study of empagliflozin as add-on to pioglitazone or pioglitazone plus metformin in patients with T2DM. The study results are evaluated, and potential impact on clinical practice is considered.
EXPERT OPINION: The addition of empagliflozin to pioglitazone or pioglitazone plus metformin treatment may offer some advantages. Together, their complementary mechanisms of action result in significant reductions in glycated hemoglobin levels, weight, and blood pressure, with a low risk of hypoglycemia, but were associated with an increased risk of events consistent with genital mycotic infections.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
