	Dopamine is a catecholamine with dopaminergic and adrenergic activity. Its primary indication is for the treatment of hypotension and bradycardia in the setting of shock and cardiac arrest. It is also used in the treatment of symptomatic bradycardia that is not responsive to atropine or pacing. It may be used as a palliative infusion for patients with chronic heart failure.
