治療心衰竭 Cardiogenic shock, septic shock, or shock due to MI, trauma, and open heart surgery; Congestive heart failure, decreased cardiac output
藥理
Dopamine hydrochloride, a natural catecholamine, is a neurotransmitter and a precursor to norepinephrine in noradrenergic nerves. It produces a positive inotropic and chronotropic effects on the myocardium by exerting an agonist action on beta-adrenoceptors and releasing norepinephrine from storage sites in sympathetic nerve endings, thus increasing heart rate and cardiac contractility.
