Trade name. generic name
|
Dopamine, inotropin
|
|
Classification
|
Adrenergic agonist, inotrope, vasopresser
|
|
MOA
|
Stimulaters alpha and beta adrenergic recepters. At Moderate doses dopamine stimulates beta 1 recepters resulting in inotropy and increased cardiac output while maintaining dopamingeric induced vasodilatory effects.
At high doses alpha adrenergic agonism predominates and increased peripheral vascular resistance and vasoconstriction result. |
|
Indications
|
Hypotension and decreased cardiac output associated with cardiogenic shock and septic shock, hypotension after return of spontaneous circulation flowing cardiac arrest, symptomatic bradycardia and unresponsibe to atropine.
|
|
Contraindications
|
Pheochromocytoma, VF,VT, or other ventricular arrhythmias known sensitivity, Correct any hypovolemia with volume fluid replacement before adminsteresting dopamine
|
|
Side Effects
|
Tachycardia, arrhythmias, skin necrosis, sever hypertension from excessive vasoconstriction, angina, dyspnea, headache and vomiting

Dosage /Route of administration
|
Adult: 2-20mcg/kg/min to desired effect. Cardiac dose is usally 5 to 10 mcg/kg/min. Vasopressor dose is usally 10 to 20 mcg/kg/min. Little benefit is gauned beyond 20 mcg/kg/min.
