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 these receptors, it inhibits ascending discomfort pathways, alters the perception of and reaction to pain, and produces generalized CNS anxiety.

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).
• Metabolic process: Hepatic via the CYP3A4 enzyme system.

• Excretion: Primarily kidney.

• Record Keeping: Every dose administered, received, or disposed of should be tape-recorded in a Controlled Drugs Register (CDR).
• Prescribing: All prescriptions need to satisfy particular legal requirements, consisting of the total amount written in both words and figures.

• Damage: Expired or infected vials need to be “rendered irretrievable” in the existence of an authorized witness.

Typical Side Effects and Adverse Reactions

While highly effective, fentanyl citrate brings a danger of significant adverse effects, especially if not titrated thoroughly.

Breathing System:The most important side effect is breathing anxiety. This is dose-dependent and can result in apnea if the patient is not kept track of or ventilated.

Cardiovascular System:Fentanyl can cause bradycardia (sluggish heart rate) and hypotension, though it is generally considered more cardiovascularly steady than morphine.

Musculoskeletal System:A special adverse effects of fast, high-dose fentanyl administration is “wooden chest syndrome” (skeletal muscle rigidity), which can make mechanical ventilation difficult.

Other Common Side Effects:

• Nausea and throwing up.
• Dizziness or bliss.
• Pruritus (itching).

• Biliary system convulsion.

Administration Guidelines

In the UK, fentanyl citrate injections are normally administered by anesthesiologists, specifically trained nurses, or emergency situation medicine clinicians.
