Beta-blockers in hypertension

Abstract

Following the early and important observations more than two decades ago, by Prichard and Gillam that beta-blockers had a useful antihypertensive effect, this class of compounds has become widely accepted in the treatment of elevated arterial pressure. Today there are numerous different compounds available within the beta-blocker class, with marked differences in their ancillary properties. Undoubtedly, the blockade of beta 1-adrenoceptors is the effect needed to achieve the reduction in blood pressure, and this selectivity also offers some advantages from a safety point of view. However, in some circumstances, ancillary properties such as beta 2-blockade may offer advantages, as can intrinsic sympathomimetic activity. The fact that beta-blockers have become first-line treatment for hypertension in many countries and that memoranda produced by the World Health Organization and the International Society of Hypertension jointly advocate beta-blockers as one alternative for basic therapy reflects the positive balance between efficacy and side effects seen with these agents. It is also an indication that positive long-term clinical experience has been accumulated with beta-blockers. Finally, secondary prevention against coronary he...Continue Reading

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
