By binding to these receptors, it inhibits rising discomfort pathways, changes the perception of and reaction to pain, and produces generalized CNS depression.Secret Pharmacokinetic Properties:Onset of Action: 1-- 2 minutes (Intravenous).Peak Effect: 3-- 5 minutes.Period: 30-- 60 minutes (much shorter than morphine due to redistribution into fat and muscle).Metabolism: Hepatic by means of the CYP3A4 enzyme system.Excretion: Primarily kidney.Regulatory and Safety Requirements in the UKDue to the fact that fentanyl citrate is a Schedule 2 Controlled Drug, its handling in the UK goes through the Misuse of Drugs Regulations 2001.
