Dopamine

DA (3,4-dihydroxyphenylethylamine; Table 10-1) is the metabolic precursor of NE and Epi; it is a central neurotransmitter particularly important in the regulation of movement (see Chapters 12, 18, and 20). In the periphery, DA is synthesized in epithelial cells of the proximal tubule and is thought to exert local diuretic and natriuretic effects. DA is a substrate for both MAO and COMT and thus is ineffective when administered orally. Classification of DA receptors is described in Chapters 12 and 20.
