Description and Uses

Dobutamine hydrochloride, a dopamine derivative, is a selective β1-adrenergic agonist. It is a sympathomimetic agent with inotropic action (changes strength of muscle contraction) on the heart. However, it may have some α and β2-agonist properties as well.The active substance strengthens the contraction power of the heart, increases the stroke volume and thus the blood circulation of the organs. It is used for the treatment of acute heart failure and for cardiac stress tests.

Dobutamine hydrochloride is a catecholamine that acts as a β-adrenergic receptor agonist with potent positive inotropic effects in vivo. It has its strongest effects on β1 receptors, with lesser but significant β2 receptor activation and only weak α1 receptor actions. As a result, it strongly increases cardiac contractility with modest chronotropic, arrhythmogenic, and vascular side effects. It is also a polyphenolic antioxidant and can inhibit all human carbonic anhydrase isoforms with Ki values near 1 ?M.
