INTRODUCTION Azilsartan medoxomil is a newly approved angiotensin-receptor blocker for the management of hypertension. It is a prodrug that is quickly hydrolyzed to the active moiety azilsartan, a potent and highly selective angiotensin-receptor blocker with estimated bioavailability of ∼ 60%. This new agent induces a potent and long-lasting antihypertensive effect. The effective therapeutic antihypertensive dosages of azilsartan medoxomil in humans vary from 40 to 80 mg/day. AREAS COVERED The authors review the results of clinical trials published in journals indexed in Medline, Scopus and Google Scholar. Primarily the authors discuss articles that analyze the safety and efficacy of azilsartan in lowering blood pressure. EXPERT OPINION Clinical trials have demonstrated that azilsartan is superior to other angiotensin-receptor blockers in lowering blood pressure. However, the clinical blood pressure trials of azilsartan published to date have been mainly conducted in patients without serious comorbidities and it is not clear if azilsartan has advantages over other angiotensin-receptor blockers in the treatment of these types of hypertensive patients. In addition, it remains to be determined whether the specific pharmacologic and pharmacokinetic characteristics of azilsartan will have a clinically significant impact on long-term cardiovascular outcomes.
