Alfentanilum est medicamentum, analgeticum opioidorum, cuius effectus sedativi haud diuturni (15 min) cum initio rapido effectuum^[2] sunt. Opioidum ipsum effectus analgeticos suos per stimulationem receptoria opioidorum perficit. Hos ob effectus Alfentanilum in chirurgia imprimis substantia anaesthetica adhibetur. Alfentanilum rigorem thoraxis intermittentem efficere potest.
