Pharmacokinetic drug evaluation of empagliflozin plus linagliptin for the treatment of type 2 diabetes.

ABSTRACT

INTRODUCTION: Type 2 diabetes mellitus has become a growing epidemic and therefore efficient treatment strategies that target its management are needed. The treatment of diabetic patients often requires the combination of antidiabetic drug classes. Sodium-glucose co-transporter 2 inhibitors (SGLT2i) block glucose reabsorption in the proximal renal tubules. Dipeptidyl peptidase-4 inhibitors (DPP-4i) improve glucose metabolism by blocking the enzyme that degrades incretins leading to increased insulin secretion. Areas covered The aim of the review is to present the available data on pharmacokinetic properties/pharmacodynamics, metabolic and cardiovascular effects of empagliflozin plus linagliptin combination. Expert opinion Both empagliflozin and linagliptin have established safety and efficacy in the treatment of diabetes. Available data demonstrate the absence of pharmacological interactions when the two drugs are given together. The complementary mechanisms of action would be expected to provide additive benefits on carbohydrate metabolism variables, but the results from clinical trials have shown that the empagliflozin/linagliptin combination provides only mild improvements of glycated hemoglobin compared with either monotherapy. However, the single-tablet formulation of empagliflozin/linagliptin is expected to provide better compliance and thus improved glycaemic control coupled with a favourable safety profile. Thus, the fixed-dose combination of empagliflozin/linagliptin has the capacity to both effectively and safely manage diabetic patients.
