Abstract
This article presents an analysis of data on the mechanisms of antihypertensive effect of β-adrenergic receptor blockers. The article describes the effectiveness of cardiotropic action of drugs to reduce high blood pressure (BP) with short-term and long-term action of compounds, the effect of blockers on the activity of plasma renin. The influence of β-blockers on the central mechanisms of blood circulation regulation is considered. Information on the effect of β-blockers on myogenic mechanisms of vascular tone regulation is presented. The possibilities of blockade of β-adrenergic receptors of endothelium-dependent hyperpolarization of smooth muscles of resistive arteries, violation of the NO-cGMP pathway and blockade of Ca2+ channel currents as factors providing expansion of resistive vessels and reduction of high BP are analyzed.
