Abstract

It is well known that norepinephrine is involved in the control of pain by modulating pain-related responses through various pathways. a2-Adrenergic agonists have a well-established analgesic profile and, in the recent years, have found a wider application, in particular as adjunct to anesthetics and analgesics in perioperative settings. This review analyzes the a2-agonists currently in clinical use, starting from the prototype Clonidine, as well as the most promising and studied molecules. In addition, an overview of the imidazoles, imidazolines, and hydroxyethyl-thioureas derivatives published in both the open and patented literature is presented, providing chemical description and pharmacological data. Finally, the most commonly a2-agonists used in veterinary medicine are described. 2008 Wiley Periodicals, Inc. Med Res Rev, 29, No. 2, 339–368, 2009
