3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is frequently used as an infusion to provide continuous analgesia for clients who are mechanically aerated. Its short half-life enables for more predictable “wake-up” tests compared to drugs like morphine.

Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding prevents ascending discomfort paths, altering the understanding of and action to pain. It likewise increases the discomfort limit.
- Onset of Action: 1— 2 minutes (Intravenous).
- Peak Effect: 3— 5 minutes.
- Period: 30— 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Since fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier almost instantly, which explains why the analgesic result is felt so much faster than with morphine or oxycodone.

Safety and Side Effects
Just like all potent opioids, fentanyl citrate carries a danger of substantial side results, especially relating to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious danger; it reduces the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically “wood chest syndrome,” where the chest wall ends up being too stiff to ventilate easily (usually happens with high-dose quick IV administration).
- Queasiness and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, frequently around the nose or upper body.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory anxiety in the absence of resuscitative equipment.
- Concurrent usage of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (threat of serotonin syndrome).
Myasthenia gravis (due to muscle-relaxing interactions).

Regulation and Storage in the UK

- Storage: It must be kept in a locked “Controlled Drugs” (CD) cupboard that meets the British Standard for security.
