Fenilefrina è un post-sinaptici alfa-stimolante, con scarso effetto sulla beta recettori del cuore. Somministrazione parenterale di fenilefrina provoca un aumento della pressione sistolica e diastolica, la gittata cardiaca è leggermente diminuito e la resistenza periferica è notevolmente aumentato, letti più vascolari sono ristretti; renale, splancnico, i flussi sanguigno cutaneo, e degli arti sono ridotti, ma il flusso sanguigno coronarico è aumentato. Vasi polmonari sono ristretti, e la pressione arteriosa polmonare è sollevata. Questo agonista del recettore alfa simpatico è utilizzato anche a livello locale perché la sua azione vasocostrittrice e midriatico.
