Answer

Adrenergic Agonists

These agents act directly on alpha- and beta-receptors, producing effects similar to those that occur following stimulation of sympathetic nerves or the release of the hormone epinephrine from the adrenal medulla.

Dobutamine (Dobutrex)

Dobutamine is a synthetic direct-acting catecholamine and beta-receptor agonist. It increases cardiac contractility and output in CHF. At therapeutic doses, it is mainly an inotropic agent, while producing comparatively mild chronotropic and vasodilative effects. As compared with other sympathomimetic drugs, dobutamine does not significantly increase myocardial oxygen demands, which is its major advantage compared with other direct-acting catecholamines.
