Summary of Available Presentations

The following table details the typical brands and presentations of fentanyl citrate injection currently used within the UK health care infrastructure.

Pharmacology and Mechanism of Action

Fentanyl acts mainly as an agonist at the mu-opioid receptors in the central worried system (CNS). By binding to these receptors, it prevents rising pain pathways, changes the perception of and action to discomfort, and produces generalized CNS depression.

Secret Pharmacokinetic Properties:

• Onset of Action: 1-- 2 minutes (Intravenous).
• Peak Effect: 3-- 5 minutes.
• Period: 30-- 60 minutes (shorter than morphine due to redistribution into fat and muscle).
• Metabolism: Hepatic via the CYP3A4 enzyme system.
• Excretion: Primarily kidney.
