The role of fixed-dose combination therapy with drugs that target the renin-angiotensin system in the hypertension paradigm

Abstract

Most patients with hypertension require two or more agents from different classes to achieve BP control. Several fixed-dose combinations are available, often combining agents that target the renin angiotensin system (angiotensin-converting enzyme [ACE] inhibitors or an angiotensin receptor blockers [ARBs]) plus either thiazide diuretics or calcium channel blockers (CCBs). At low doses, these combinations may have greater efficacy and better tolerability than the respective high dose monotherapies. Combining an ARB (instead of an ACE inhibitor) with the CCB amlodipine offers efficacy with improved tolerability. This review aims to highlight the simplicity, tolerability, and convenience of fixed-dose combinations targeting the renin-angiotensin system, which can lead to improved compliance and more patients achieving BP goals.
