Flexyx drugs: Dobutamine Hcl

Dobutamine Hcl - General Information:

A beta-2 agonist catecholamine that has cardiac stimulant action without evoking vasoconstriction or tachycardia. It is proposed as a cardiotonic after myocardial infarction or open heart surgery. [PubChem]

Pharmacology:

Dobutamine Hcl is a direct-acting inotropic agent whose primary activity results from stimulation of the beta-adrenoceptors of the heart while producing comparatively mild chronotropic, hypertensive, arrhythmogenic, and vasodilative effects. Dobutamine Hcl acts primarily on beta-1 adrenergic receptors, with little effect on beta-2 or alpha receptors. It does not cause the release of endogenous norepinephrine, as does dopamine. Dobutamine Hcl is indicated when parenteral therapy is necessary for inotropic support in the short-term treatment of patients with cardiac decompensation due to depressed contractility resulting either from organic heart disease or from cardiac surgical procedures.

Dobutamine Hcl for patients

Dobutamine Hcl Interactions

Animal studies indicate that dobutamine may be ineffective if the patient has recently received a b-blocking drug. In such a case, the peripheral vascular resistance may increase.

Preliminary studies indicate that the concomitant use of dobutamine and nitroprusside results in a higher cardiac output and, usually, a lower pulmonary wedge pressure than when either drug is used alone.

There was no evidence of drug interactions in clinical studies in which dobutamine was administered concurrently with other drugs, including digitalis preparations, furosemide, spironolactone, lidocaine, glyceryl trinitrate, isosorbide dinitrate, morphine, atropine, heparin, protamine, potassium chloride, folic acid, and acetaminophen.

Dobutamine Hcl Contraindications

Dobutamine is contraindicated in patients with idiopathic hypertrophic subaortic stenosis and in patients who have shown previous manifestations of hypersensitivity to dobutamine.

Dobutamine Hcl Indication: For inotropic support in the short- term treatment of patients with cardiac decompensation due to depressed contractility resulting either from organic heart disease or from cardiac surgical procedures
Mechanism Of Action: Dobutamine Hcl directly stimulates beta-1 receptors of the heart to increase myocardial contractility and stroke volume, resulting in increased cardiac output.
