Dopamine is a monoamine compound with positive inotropic activity, a naturally occurring catecholamine, and a neurotransmitter formed by the decarboxylation of dihydroxyphenylalanine and a precursor of norepinephrine and epinephrine. Dopamine binds to alpha-1 and beta-1 adrenergic receptors. Mediated by myocardial beta-1 adrenergic receptors, dopamine increases heart rate and contractility, thereby enhancing cardiac output. Alpha-1 adrenergic receptor stimulation on vascular smooth muscle leads to vasoconstriction and an increase in systemic vascular resistance. Stimulation of dopaminergic receptors in the renal vascular system leads to dilation of the renal vessels and an increase in the glomerular filtration rate, renal blood flow, sodium excretion, and urine output. Dopamine is also an important neurotransmitter in the extrapyramidal system of the brain and is important for, among other things, motor regulation. See also: dopamine hydrochloride.
