Effects of Combination of Perindopril, Indapamide, and Calcium Channel Blockers in Patients With Type 2 Diabetes Mellitus
Results From the Action in Diabetes and Vascular Disease: Preterax and Diamicron Controlled Evaluation (ADVANCE) Trial
The objective of the present analysis was to determine the effects of a fixed combination of perindopril and indapamide in combination with calcium channel blockers (CCBs) in patients with type 2 diabetes mellitus. The Action in Diabetes and Vascular Disease: Preterax and Diamicron Controlled Evaluation (ADVANCE) trial was a factorial randomized controlled trial. A total of 11 140 patients with type 2 diabetes mellitus were randomly assigned to fixed combination of perindopril–indapamide (4/1.25 mg) or placebo. Effects of randomized treatment on mortality and major cardiovascular outcomes were examined in subgroups defined by baseline use of CCBs. Patients on CCB at baseline (n=3427) constituted a higher risk group compared with those not on CCB (n=7713), with more extensive use of antihypertensive and other protective therapies. Active treatment reduced the relative risk of death by 28% (95% confidence interval, 10%–43%) among patients with CCB at baseline compared with 5% (−12% to 20%) among those without CCB (P homogeneity=0.02) and 14% (2%–25%) for the whole population. Similarly, the relative risk reduction for major cardiovascular events was 12% (−8% to 28%) versus 6% (−10% to 19%) for those with and without CCB at baseline although the difference was not statistically significant (P homogeneity=0.38). There was no detectable increase in adverse effects in those receiving CCB. The combination of perindopril and indapamide with CCBs seems to provide further protection against mortality in patients with type 2 diabetes mellitus.
