Antihyperglycemic and Metabolic Effects of Ranolazine in Patients With Diabetes Mellitus

Abstract

The antianginal drug ranolazine, because of its unique mechanism of action, has been shown to have antihyperglycemic effects. Here, we review the reports on the antihyperglycemic and metabolic effects of ranolazine. MEDLINE was searched from 2000 to October 1, 2016 using the terms ranolazine, antihyperglycemic, diabetes, cardiology, and antianginal. Studies and reviews were included if they were in English and provided relevant data to inform practicing clinicians. Ranolazine has been shown to be effective as an antihyperglycemic while utilized as monotherapy or in combination with traditional diabetic regimens. A total of 6 studies were included in this review, with 5 being randomized controlled trials and 1 being a retrospective study. Of the 6 studies, 4 directly measured differences between baseline hemoglobin A1c (HbA1c), another measured endothelium function, and lastly the retrospective study evaluated outpatient clinic visit utilization, all-cause emergency department visits, inpatient admissions, and length of stay in a cohort of patients with angina and diabetes. In conclusion, ranolazine, because of its unique mechanism of action, may have a niche in therapy for patients with chronic stable angina pectoris and diabetes mellitus. Ranolazine has been shown to have positive antihyperglycemic and metabolic effects in patients with uncontrolled HbA1c.
