Drug Index


Mechanism :

Dobutamine is a direct-acting inotropic agent whose primary activity results from stimulation of the b-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.

Indication :

  • Cardiac failure
  • Cardiac surgery
  • Septicemia
  • Myocardial stress testing

Contraindications :

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

Dosing :

Continuous IV infusion: 2-10 microgram/kg/min increased to a max of 20 microgram/kg/min in newborn and 40 microgram/kg/min in older children if necessary.
Suggested drip administration: 6 x wt (kg) x desired dose (mcg/kg/min)/desired fluid rate (Ml/hr) = mg of dobutamine per 100 ml solution.

Adverse Effect :

Chest pain, tachycardia, angina, ectopic beats, palpitation, hypertension, nausea, vomiting, tingling sensation, paraesthesia, dyspnea, headache, hypersensitivity (rash, fever, bronchospasm), hypokalemia.

Interaction :

Nitroprusside: Concomitant use of dobutamine and nitroprusside results in a higher cardiac output and, a lower pulmonary wedge pressure than when either drug is used alone.
