Pharmacology and Mechanism of Action
Fentanyl acts primarily as an agonist at the mu-opioid receptors in the main nerve system (CNS). By binding to learn more , it hinders rising pain pathways, modifies the perception of and action to pain, and produces generalized CNS anxiety.
Secret Pharmacokinetic Properties:
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (shorter than morphine due to redistribution into fat and muscle).

- Excretion: Primarily kidney.
