Best Answer

its depend upon the dosage of dopamine given via iv

2 to 5microgram/kg/min called renal dosage it binds to D1 receptor which causes dilation of blood vessel,increasing blood flow to the renal ,mesenteric and coronary arteries

5 to10 microgram/kg/min have positive inotropic and chronotropic effect by acting on beta1 receptor on heart

10 to 20 microgram/kg/min causes vasoconstriction by acting on alpha1 receptor
