Mechanism of Action and Pharmacokinetics

Fentanyl works by binding to mu-opioid receptors. This binding prevents rising discomfort paths, changing the perception of and action to pain. It likewise increases the pain limit.

• Onset of Action: 1-- 2 minutes (Intravenous).
• Peak Effect: 3-- 5 minutes.
• Period: 30-- 60 minutes (making it highly titratable).
• Metabolism: Primarily in the liver through the CYP3A4 enzyme.
• Excretion: Mostly via the kidneys.

Due to the fact that fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly instantly, which explains why the analgesic effect is felt a lot faster than with morphine or oxycodone.

Security and Side Effects

• Nausea and Vomiting: Common in the post-operative stage.
• Pruritus: Itching, typically around the nose or upper body.

Contraindications and Cautions:

• Known hypersensitivity to fentanyl or other opioid agonists.
• Respiratory anxiety in the lack of resuscitative equipment.
• Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (risk of serotonin syndrome).
• Myasthenia gravis (due to muscle-relaxing interactions).

Guideline and Storage in the UK

In the United Kingdom, fentanyl citrate is strictly controlled to prevent diversion and misuse.

• Storage: It must be kept in a locked "Controlled Drugs" (CD) cabinet that fulfills the British Standard for security.
• Record Keeping: Every dosage administered should be recorded in a Controlled Drugs Register, signed by two qualified health care professionals (generally a doctor and a nurse, or more nurses).
