Adrenergic and Cholinergic Compounds.

Adrenergic and cholinergic signalling contributes significantly to the endogenous antinociceptive system. Exogenous α2 adrenergic agonists have a well-established analgesic profile; however, recent investigations suggest that this class of agents is underused, and herein we highlight the potential for both current application and future development of these agents. Nicotinic and muscarinic cholinergic ligands represent a novel class of agents with much promise for the management of problematic pain. In this chapter we review advances in both preclinical and clinical arenas and highlight potential avenues for further research. [ABSTRACT FROM AUTHOR]
