Abstract
The antihypertensive agents olmesartan medoxomil, amlodipine and hydrochlorothiazide (HCTZ) are now available as a fixed-dose combination tablet (olmesartan medoxomil/amlodipine/HCTZ).
In a 12-week, randomized, double-blind, multi-centre trial (TRINITY) in adults with moderate to severe hypertension, olmesartan medoxomil + amlodipine + HCTZ triple combination therapy produced significantly greater least squares mean reductions from baseline in seated diastolic blood pressure (BP) [primary endpoint] and seated systolic BP than olmesartan medoxomil/amlodipine, olmesartan medoxomil/HCTZ or amlodipine + HCTZ.
Furthermore, significantly more patients achieved BP goals and targets with the triple combination regimen than with any of the dual combination regimens at week 12, with olmesartan medoxomil + amlodipine + HCTZ also demonstrating benefit over the dual regimens in terms of ambulatory BP control.
According to subgroup analyses of the TRINITY trial, olmesartan medoxomil + amlodipine + HCTZ was more effective in reducing BP and achieving BP goals than each of the dual therapies, irrespective of hypertension severity, age, sex, race or diabetes mellitus status.
Data from a number of smaller clinical studies indicated that olmesartan medoxomil + amlodipine+ HCTZ triple combination therapy provides antihypertensive efficacy in patients whose BP is not adequately controlled with olmesartan medoxomil + amlodipine.
Olmesartan medoxomil + amlodipine + HCTZ was generally well tolerated in the TRINITY study, with adverse events usually being mild or moderate in severity.
