Answer
Vasopressors
These agents are used to increase blood pressure.
Phenylephrine (Neo-Synephrine)
Strong postsynaptic alpha-receptor stimulant with little beta-adrenergic activity. Vasoconstricts arterioles and increases venous return.
Dopamine (Intropin)
Naturally occurring endogenous catecholamine that stimulates dopaminergic, beta1-adrenergic, and alpha1-adrenergic receptors in dose-dependent fashion. At 2-5 mcg/kg/min, acts on dopaminergic receptors in renal and splanchnic vascular beds, causing their vasodilation. At 5-15 mcg/kg/min, acts on beta-adrenergic receptors to increase heart rate and contractility. At 15-20 mcg/kg/min, acts on alpha-adrenergic receptors to increase systemic vascular resistance and raise BP.
