Pharmacology and Mechanism of Action
Fentanyl acts mainly as an agonist at the mu-opioid receptors in the central nervous system (CNS). By binding to these receptors, it hinders ascending discomfort pathways, alters the understanding of and reaction to discomfort, 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 by means of the CYP3A4 enzyme system.
- Excretion: Primarily renal.
Regulatory and Safety Requirements in the UK

- Record Keeping: Every dose administered, received, or disposed of should be recorded in a Controlled Drugs Register (CDR).
- Prescribing: All prescriptions must meet specific legal requirements, consisting of the overall amount composed in both words and figures.
- Destruction: Expired or infected vials need to be "rendered irretrievable" in the presence of an authorized witness.
Common Side Effects and Adverse Reactions
While extremely efficient, fentanyl citrate carries a risk of considerable negative effects, especially if not titrated thoroughly.
Respiratory System:The most crucial adverse effects is breathing anxiety. This is dose-dependent and can lead to apnea if the client is not monitored or ventilated.
Cardiovascular System:Fentanyl can trigger bradycardia (slow heart rate) and hypotension, though it is usually thought about more cardiovascularly steady than morphine.
Musculoskeletal System:An unique negative effects of quick, high-dose fentanyl administration is "wood chest syndrome" (skeletal muscle rigidness), which can make mechanical ventilation difficult.
Other Common Side Effects:
- Nausea and throwing up.
- Dizziness or euphoria.
- Pruritus (itching).
- Biliary system spasm.
Administration Guidelines
In the UK, fentanyl citrate injections are generally administered by anesthesiologists, specifically trained nurses, or emergency situation medication clinicians.

- Constant Infusion: Common in the ICU for long-term sedation. Concentrations are often standardized by local hospital trusts (e.g., 1mg in 50ml or 2.5 mg in 50ml).
- Patient-Controlled Analgesia (PCA): Less common than morphine PCAs, but made use of for patients with morphine allergic reactions or renal disability.
