Adrenergic and dopamine agonist. Dopamine is a neurotransmitter and an immediate precursor to norepinephrine. At low doses it stimulates the dopamine (DA1) receptors, at moderate doses it stimulates the adrenergic receptors, and at high doses it acts as an alpha1-receptor agonist (producing vasoconstriction). At doses that stimulate DA1 receptors, it increases c-AMP in smooth muscle cells and causes relaxation and vasodilation. It has been administered to stimulate the heart and to increase urine flow (see below for explanation of renal effects).
Dopamine is used therapeutically to stimulate myocardium via action on cardiac beta1-receptors. Dopamine infusions will increase both blood pressure and cardiac output. These effects are caused by stimulating cardiac contractility and heart rate by acting as an agonist for beta1-adrenergic receptors. In addition, dopamine increases the release of norepinephrine from nerve terminals (dopamine is a precursor for norepinephrine). It produces a greater chronotropic effect than dobutamine. It has been proposed that dopamine dilates renal arterioles, increases renal blood flow, and increases the glo
