Initial dose: 2 to 10 mcg/kg/min IV by continuous infusion Maintenance dose: 2 to 50 mcg/kg/min IV by continuous infusion Comments: -Patients with advanced circulatory decompression states have been given rates greater than 50 mcg/kg/min. Levodopa also has side effects. Dopamine/Dopamine Hydrochloride/Dopamine Hydrochloride, Dextrose/Dopamine, Dextrose/Intropin Intravenous Inj Sol: 1mL, 40mg, 80mg, 160mg, 200-5%, 400-5%, 800-5% DOSAGE & INDICATIONS For the treatment of hemodynamic imbalances present in shock syndrome due to chronic cardiac decompensation as in congestive heart failure.

If hypotension persists, treatment should be discontinued and a more potent vasoconstriction agent should be used (e.g., norepinephrine). Dopaminergic drugs are used when problems related to dopamine arise. Umbilical arterial catheter administration should be avoided. Treatment of hypotension, low cardiac output, poor perfusion of vital organs; used to increase mean arterial pressure in septic shock patients who remain hypotensive after adequate volume expansion, 1-5 mcg/kg/min IV (low dose): May increase urine output and renal blood flow, 5-15 mcg/kg/min IV (medium dose): May increase renal blood flow, cardiac output, heart rate, and cardiac contractitlity, 20-50 mcg/kg/min IV (high dose): May increase blood pressure and stimulate vasoconstriction; may not have a beneficial effect in blood pressure; may increase risk of tachyarrhythmias, May increase infusion by 1-4 mcg/kg/min at 10-30 min intervals until optimum response obtained, Strong beta1-adrenergic, alpha-adrenergic, and dopaminergic effects are based on dosing rate, 1-5 mcg/kg/min IV, increased to 5-20 mcg/kg/min; not to exceed 50 mcg/kg/min, Orphan designation for prevention of intraventricular hemorrhage in premature neonates, Cardiovascular: Ventricular arrhythmia, atrial fibrillation (at very high doses), ectopic beats, tachycardia, anginal pain, palpitation, cardiac conduction abnormalities, widened QRS complex, bradycardia, hypotension, hypertension, vasoconstriction, Central nervous system: Headache, anxiety, Ocular: Increased intraocular pressure; dilated pupils, Gangrene of extremities has occurred when high doses were administered for prolonged periods or in patients with occlusive vascular disease receiving low doses of dopamine hydrochloride, May cause peripheral ischemia in patients with history of occlusive vascular disease, If ischemia occurs, prevent sloughing and necrosis in ischemic areas by infiltrating areas as soon as possible with 5-10 mg of phentolamine (adrenergic blocking agent) in 10-15 mL of saline solution, Hypersensitivity to dopamine, pheochromocytoma, ventricular fibrillation, uncorrected tachyarrhythmias, Use caution in angina pectoris, extravasation, hypovolemia, occlusive vascular disease, ventricular arrhythmias, recent use of monoamine oxidase inhibitors, sensitivity to sulfites, Use with caution after myocardial infarction, Use caution in patients taking MAO inhibitors; prolong hypertension may occur with concurrent use, Lactation: Unknown whether drug is excreted into breast milk; use caution. -Renal: Urine flow/output, renal function tests Consult WARNINGS section for additional precautions. Endogenous catecholamine, acting on both dopaminergic and adrenergic neurons, Low dose stimulates mainly dopaminergic receptors, producing renal and mesenteric vasodilation; higher dose stimulates both beta1-adrenergic and dopaminergic receptors, producing cardiac stimulation and renal vasodilation; large dose stimulates alpha-adrenergic receptors, Metabolized in liver, kidney, and plasma by monoamine oxidase and catechol-O-methyl transferase, Metabolites: Norepinephrine (active), inactive metabolites, Additive: Acyclovir, alteplase, amphotericin B, ampicillin, gentamicin(? Dopamine is an immediate catecholamine precursor of noradrenaline that directly stimulates alpha, beta and peripheral dopaminergic receptors in a dose-dependent manner, as well as acting indirectly by releasing endogenous noradrenaline from storage sites in sympathetic nerve endings. As an exogenous agent, it produces a dose-dependent activation of several types of adrenergic and dopaminergic receptors. -Patients should undergo circulatory volume restoration before starting this drug. 827930-overview The Dopamine dose your doctor recommends will be based on the following (use any or all that apply): the condition being treated; Adding plans allows you to compare formulary status to other drugs in the same class.
