Mechanism of Action: Strong alpha-adrenergic effects, which cause an increase in cardio output and HR, a decrease in renal perfusion and PVR, and a variable effect on BP, resulting in systemic vasoconstriction and increased vascular permeability

Strong beta1- and moderate beta2-adrenergic effects, resulting in bronchial smooth muscle relaxation. Secondary relaxation effect on smooth muscle of stomach, intestine, uterus, and urinary bladder

Classification; bronchodilator nonselective adrenergic agonist, vasopressor
