Pharmacology and Mechanism of Action
Fentanyl acts primarily as an agonist at the mu-opioid receptors in the central anxious system (CNS). By binding to these receptors, it prevents rising discomfort pathways, changes the perception of and reaction to discomfort, and produces generalized CNS depression.
Key Pharmacokinetic Properties:
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (shorter than morphine due to redistribution into fat and muscle).
- Metabolic process: Hepatic through the CYP3A4 enzyme system.
- Excretion: Primarily renal.

- Record Keeping: Every dose administered, gotten, or disposed of must be recorded in a Controlled Drugs Register (CDR).
- Recommending: All prescriptions need to fulfill specific legal requirements, including the total quantity composed in both words and figures.
- Damage: Expired or contaminated vials should be "rendered irretrievable" in the existence of an authorized witness.
Typical Side Effects and Adverse Reactions
While extremely reliable, fentanyl citrate brings a danger of significant negative effects, especially if not titrated carefully.
Breathing System:The most important adverse effects is respiratory depression. This is dose-dependent and can cause apnea if the patient is not kept track of or ventilated.
Cardiovascular System:Fentanyl can trigger bradycardia (slow heart rate) and hypotension, though it is normally considered more cardiovascularly stable than morphine.
Musculoskeletal System:An unique side impact of quick, high-dose fentanyl administration is "wooden chest syndrome" (skeletal muscle rigidness), which can make mechanical ventilation hard.
