Phenylephrine vasoconstrictor
WebPhenylephrine is a synthetic noncatecholamine α1 agonist and produces dose-dependent vasoconstriction of cutaneous, muscular, mesenteric, splanchnic, and renal vasculature (see Table 22-1 ). Systemic arterial vasoconstriction increases systolic, diastolic, and mean arterial pressures, with reflex bradycardia. WebPhenylephrine is a pure vasoconstrictor and is not recommended for empiric use, although niche uses for phenylephrine include (1) difficulty raising mean arterial pressure in the presence of high cardiac output as well as (2) serious tachyarrhythmias induced by norepinephrine (not usually an issue).
