Abstract

A great deal of new information on alpha 2-adrenoceptor agonists has recently been accumulated in humans; alpha 2-agonists have several beneficial actions in clinical anesthesia including sedative, anxiolytic as well as analgesic effects, improved hemodynamic stability, and etc. In the first part of this review, we summarized the structure, signal transmission and basic pharmacology of alpha 2-adrenoceptor agonists (clonidine and dexamedetomidine), and evaluated their usefulness for premedication, and as anesthetic adjuvants as well as agents for stabilizing circulation in the clinical settings. In addition, we referred to practical problems associated with their use.

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.
