商品名：Dobutrex
Adrenergic agonist. Dobutamine is a racemic mixture (R and S isomers) that has both beta1- and beta2-adrenergic activity. However, its clinical effects are caused by the relative cardioselective agonist activity on beta1 receptors. There are both agonist and antagonist effects on alpha-receptors, the clinical effects of which are uncertain. The primary advantage of dobutamine is that it produces positive inotropic effects without excessive tachycardia. The lack of tachycardia distinguishes it from other sympathomimetic agents. At appropriate infusion rates, dobutamine can improve contractility
Dobutamine is used primarily for the acute treatment of heart failure. It produces an inotropic effect without increasing heart rates. Short treatment regimens (e.g., 48 hours) can have a residual positive effect in some animals.
