Definition
Fentanyl is a potent and rapid-onset synthetic opioid that is a phenylpiperidine derivative.
Characteristics
Fentanyl is a derivative of 4-anilinoperidine and is structurally related to pethidine. It is commercially formulated as a citrate, a white crystalline solid that is readily soluble in acidic aqueous solutions. It has a pKa of 8.4, and each ml of aqueous solution contains 0.05 mg fentanyl base (0.0785 mg of the citrate). It is a highly lipophilic drug and produces analgesia, respiratory depression, vagal effects, emesis, constipation, and physical dependence.
Pharmacology
Fentanyl is an opioid analgesic that binds predominantly to mu (μ) receptors. Its primary therapeutic actions are analgesia and sedation. Mood alterations, euphoria, and dysphoria are common. Fentanyl also depresses the...
