Central imidazoline receptors as a target for centrally acting antihypertensive drugs

Abstract

Imidazoline (I1)-receptors in the central nervous system play a role in the central regulation of blood pressure and heart rate. Stimulation of these receptors in the rostral ventrolateral medulla induces peripheral sympathoinhibition, and hence a reduction of elevated blood pressure. The imidazoline derivatives moxonidine and rilmenidine are moderately selective I1 receptor stimulants which have been introduced as centrally acting antihypertensives. Since they have little affinity for alpha 2-adrenoceptors, they may be expected to cause less sedation and dry mouth than the alpha 2-adrenoceptor agonists clonidine and methyldopa. The concept of I1 receptors and their agonists therefore offers the possibility to develop centrally acting antihypertensives with a more favourable profile of adverse reactions than the classical alpha 2-adrenoceptor stimulants such as clonidine and methyldopa.

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.

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.
