Emerging drugs in the management of hypertension

Abstract

Hypertension is a global health problem, affecting developing and developed countries alike. Most patients with hypertension are undiagnosed, and most diagnosed patients are either untreated or inadequately treated. Randomised controlled trial evidence suggests diuretic therapy for hypertension is as effective as newer drugs in reducing cardiovascular events. There is good evidence for the use of specific classes of drugs in hypertensive patients with a variety of associated clinical conditions, but for uncomplicated cases, the current emphasis in hypertension management is on blood pressure lowering rather than drug class. Individual patients vary in their responses to different drug classes, and optimal therapy for the individual is determined by trial and error. Pharmacogenomics may assist in tailoring therapy for individuals in the future. Emerging drugs include newer members of classes already established in clinical practice, for example, angiotensin II receptor antagonists, aldosterone receptor antagonists, calcium antagonists and centrally acting drugs; newer fixed-dose combination therapies; and more novel therapies, for example, endothelin (ET) receptor antagonists, activators of nitric oxide (NO)-sensitive guanylyl cyclase and vasopeptidase inhibitors.
