Pharmacokinetics and Pharmacodynamics Understanding how the body processes fentanyl is important for safe administration
Beginning of Action When administered intravenously the effect starts nearly instantly though the optimum analgesic impact might take 3 to 5 minutes Duration A single intravenous dose of 100 micrograms typically lasts for 30 to 60 minutes Metabolism Fentanyl is mostly metabolised in the liver through the CYP3A4 enzyme system Excretion Approximately 75 of the dose is excreted in the urine within 24 hours primarily as metabolites Administration Protocols In the UK the administration of fentanyl citrate is strictly managed and typically performed by anaesthetists or trained professionals in regulated environments
Dosage Guidelines Dosage must be horizontal and individualised based on the clients age weight physical status underlying pathological condition use of other drugs and the kind of surgery
Low Dose 2 mcgkg Useful for minor surgical treatments Moderate Dose 2 20 mcgkg Used when surgery is more invasive requires respiratory tracking High Dose 20 50 mcgkg Used during troublefree significant surgeries eg openheart surgical treatment to safeguard the myocardium from the metabolic demands of tension Paths of Administration Intravenous IV Bolus Common for induction Intravenous Infusion Used for longer treatments or in the ICU Intramuscular IM Less common but used for premedication in particular circumstances Regulative Status and Safety In the United Kingdom Fentanyl is classified under the Misuse of Drugs Act 1971 as a Class A drug Under the Misuse of Drugs Regulations 2001 it is classified as a Schedule 2 Controlled Drug CD POM

Respiratory Depression The most major adverse effects which can cause respiratory arrest if not kept an eye on Bradychardia Often managed with atropine Muscle Rigidity Chest Wall Rigidity High dosages can make ventilation difficult requiring using neuromuscular blocking agents Nausea and Vomiting Common in the postoperative duration Hypotension Although more stable than morphine it can still take place especially in hypovolaemic patients Comparison with Other Opioids Clinicians typically pick fentanyl over other opioids due to its particular pharmacokinetic profile
