Does canagliflozin reduce mean 24-hour systolic BP in patients with type 2 diabetes mellitus and hypertension?
Canagliflozin 300 mg rapidly and significantly reduces 24-hour ambulatory systolic blood pressure over 6 weeks in patients with type 2 diabetes and hypertension.
This randomized, double-blind, placebo-controlled study evaluated the early effects of canagliflozin on blood pressure (BP) in patients with type 2 diabetes mellitus (T2DM) and hypertension. Patients were randomized to canagliflozin 300 mg, canagliflozin 100 mg, or placebo for 6 weeks and underwent 24-hour ambulatory BP monitoring before randomization, on day 1 of treatment, and after 6 weeks. The primary endpoint was change in mean 24-hour systolic BP (SBP) from baseline to week 6. Overall, 169 patients were included (mean age, 58.6 years; glycated hemoglobin, 8.1%; seated BP 138.5/82.7 mm Hg). At week 6, canagliflozin 300 mg provided greater reductions in mean 24-hour SBP than placebo (least squares mean -6.2 vs -1.2 mm Hg, respectively; P=.006). Numerical reductions in SBP were observed with canagliflozin 100 mg. Canagliflozin was generally well tolerated, with side effects similar to those reported in previous studies. These results suggest that canagliflozin rapidly reduces BP in patients with T2DM and hypertension.
