The History and Pharmacology of Dopamine Agonists

Abstract

ABSTRACTThe recognition of the dopaminergic properties of some ergot derivatives has initiated new therapeutical approaches in endocrinology as well as in neurology. The pharmacological characterization of the different ergot derivatives during the last decade has largely improved our understanding of central dopaminergic systems. Their development has yielded valuable information on the pharmacology of dopamine receptors involved in the regulatory mechanisms of prolactin secretion and in striatal functions.The clinical application of such new neurobiological concepts has underlined the therapeutical interest of such compounds either in the control of prolactin-dependent endocrine disorders or in the treatment of parkinsonism. Owing to their pharmacological profiles, dopaminergic agonists represent a valuable clinical option especially in the management of Parkinson’s disease in view of the problems arising from chronic L-Dopa treatment.
