title: Dopamine: receptors and clinical applications.
abstract: Dopamine (DA) receptors have been divided into two subtypes: DA1 receptors which subserve vasodilation in renal, mesenteric, coronary, and cerebral vascular beds, and DA2 receptors which when activated cause inhibition of release of norepinephrine in sympathetic nerve endings. The subdivisions were made on the basis of differences in chemical structure and potency series of agonists and antagonists for the two receptor subtypes. Agonists and antagonists are now available which selectively act on DA1 or DA2 receptors. The clinical use of DA, DA pro-drugs, and selective DA agonists is discussed with particular emphasis on the treatment of congestive heart failure and hypertension. Finally, data are presented concerning possible relationships between peripheral DA1 and DA2 receptors and DA receptors classified in the central nervous system.
