| | Dobutamine hydrochloride Usage And Synthesis |
| Description | 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. | | Chemical Properties | Dobutamine hydrochloride occurs as a white to off-white crystalline powder, which is sparingly soluble in water and in alcohol. Dobutamine has a pKa of 9.4. | | Uses | Dobutamine Hydrochloride is a sympathomimetic drug used to treat heart failure by inhibiting β1 receptors in the sympathetic nervous system. Cardiotonic.
| | Uses | 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. | | Definition | ChEBI: The hydrochloride salt of dobutamine. A beta1-adrenergic receptor agonist that has cardiac stimulant action without evoking vasoconstriction or tachycardia, it is used to increase the contractility of the heart in the m
nagement of acute heart failure. | | Brand name | Dobutrex (Lilly）. | | Biological Activity | β 1 - and β 2 -adrenoceptor agonist with some action at the α 1 -adrenoceptor. | | Biochem/physiol Actions | Dobutamine is a synthetic catecholamine that stimulate the β1 -adrenoceptor receptor. It exhibits inotropic outcome on the myocardium. Dobutamine elevates contractility and is known to be useful in the condition of low blood pressure. | | Pharmacokinetics | Dobutamine hydrochloride is a direct-acting inotropic agent whose primary activity results from stimulation of the beta-receptors of the heart while producing comparatively mild chronotropic, hypertensive, arrhythmogenic, and vasodilative effects. It does not cause the release of endogenous norepinephrine, as does dopamine. In animal studies, dobutamine produces less increase in heart rate and less decrease in peripheral vascular resistance for a given inotropic effect than does isoproterenol. | | Veterinary Drugs and Treatments | Dobutamine is used as a rapid-acting injectable positive inotropic
agent for short-term treatment of heart failure. It is also useful in
shock patients when fluid therapy alone has not restored
acceptable
arterial blood pressure, cardiac output, or tissue perfusion. | | storage | Desiccate at RT |
