The comparative effects of azilsartan medoxomil and olmesartan on ambulatory and clinic blood pressure.

ABSTRACT: The current study assesses the antihypertensive efficacy and safety of the investigational angiotensin receptor blocker (ARB), azilsartan medoxomil (AZL-M), compared with placebo and the ARB olmesartan medoxomil (OLM-M). This randomized, double-blind, placebo-controlled, multicenter study assessed change from baseline in mean 24-hour ambulatory systolic blood pressure (SBP) following 6 weeks of treatment. Patients with primary hypertension (n=1275) and baseline 24-hour mean ambulatory systolic pressure ≥ 130 mm Hg and ≤ 170 mm Hg were studied; 142 received placebo and the remainder received 20 mg, 40 mg, or 80 mg AZL-M or 40 mg OLM-M. Mean age of participants was 58 ± 11 years, baseline mean 24-hour SBP was 146 mm Hg. Dose-dependent reductions in 24-hour mean SBP at study end occurred in all AZL-M groups. Reduction in 24-hour mean SBP was greater with AZL-M 80 mg than OLM-M 40 mg by 2.1 mm Hg (95% confidence interval, -4.0 to -0.1; P=.038), while AZL-M 40 mg was noninferior to OLM-M 40 mg. The side effect profiles of both ARBs were similar to placebo. AZL-M is well tolerated and more efficacious at its maximal dose than the highest dose of OLM-M.

Project description:BackgroundAngiotensin receptor blockers (ARBs) are preferred antihypertensive therapies in patients with type 2 diabetes mellitus (T2DM). Azilsartan medoxomil (AZL-M) is a potent ARB for the treatment of stages 1-2 hypertension. We compared the efficacy, safety, and metabolic effects of AZL-M to both valsartan (VAL) and olmesartan (OLM), separately in patients with impaired fasting glucose (prediabetes mellitus) and T2DM.MethodsA pooled analysis of 3821 patients from three separate randomized placebo-controlled trials comparing the effects of AZL-M (40 and 80 mg), OLM (40 mg), VAL (320 mg), and placebo on changes in ambulatory and clinic blood pressure (BP) among patients with hypertension and prediabetes mellitus or T2DM was performed. Two analysis pools were created to facilitate comparisons: Pool A included patients who received placebo, AZL-M or OLM and Pool B included those who received AZL-M or VAL. Within each pool, patients were stratified by glycemic subgroups (normoglycemic, prediabetes mellitus, or T2DM) based on hemoglobin A1c values. Changes from baseline in both 24-h and clinic SBP were the primary efficacy assessments.ResultsBaseline 24-h mean SBPs were approximately 145 and 146 mmHg in the prediabetes mellitus and T2DM subgroups, respectively; corresponding clinic SBPs were approximately 158 and 159 mmHg. Baseline hemoglobin A1c values for each subgroup (both pools) were normoglycemic, 5.3%; prediabetes mellitus, 6.0%; and T2DM, 6.9%. Changes from baseline in 24-h or clinic SBP were significantly greater with AZL-M, 80 mg compared with either OLM 40 mg or VAL 320 mg in all subgroups in each pool. Safety and tolerability were similar among the active treatment and placebo subgroups.ConclusionThese analyses indicate that AZL-M, 80 mg/day lowers SBP by a greater magnitude than OLM or VAL at maximally approved doses in patients with prediabetes mellitus and T2DM. These findings have important clinical implications for this high-risk patient group.
