Abstract
Objective
The comparison of antihypertensive effects between azilsartan and olmesartan in patients with essential hypertension has been investigated in several studies. The results were not consistent. We performed this meta-analysis determining the antihypertensive effect of azilsartan versus olmesartan in patients with essential hypertension.
Methods
Pubmed, Web of Science, and Cochrane Central were searched for all published randomized studies comparing the antihypertensive effects between azilsartan and olmesartan in patients with essential hypertension.
Results
The antihypertensive effects were assessed in 1402 patients included in five trials. The reduction of office systolic blood pressure treated with azilsartan was greater than olmesartan (weighted mean differences (WMD) − 2.15 (95% confidence interval (CI), − 3.78, − 0.53) mm Hg, p < 0.01). There was no significant difference in reduction of office diastolic blood pressure between azilsartan and olmesartan (WMD − 0.99 (95% CI, − 2.06, 0.08) mm Hg, p > 0.05). The reduction of office systolic blood pressure treated with azilsartan was greater than olmesartan at same dose for both drugs (WMD − 2.24 (95% CI, − 4.03, − 0.44) mm Hg, p < 0.05), whereas there was no significant difference in reduction of office diastolic blood pressure between azilsartan and olmesartan (WMD − 0.55 (95% CI, − 1.76, 0.66) mm Hg, p > 0.05).
Conclusions
This meta-analysis provides the evidence that the reduction of office systolic blood pressure treated with azilsartan was greater than olmesartan in patients with essential hypertension. These findings suggest the importance of strict designed randomized controlled trials in determining antihypertensive effects of angiotensin II receptor blockers in clinical practice.
