FENTANYL-62 vs FENTANYL CITRATE AND DROPERIDOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fentanyl is a synthetic opioid agonist primarily acting on mu-opioid receptors in the central nervous system, leading to analgesia, sedation, and respiratory depression.
Fentanyl is a mu-opioid receptor agonist, producing analgesia and sedation. Droperidol is a butyrophenone antipsychotic that blocks dopamine D2 receptors in the brain, causing tranquilization and antiemetic effects.
For analgesia: 50-100 mcg IV/IM every 1-2 hours as needed. For anesthesia: 2-50 mcg/kg IV. For PCA: 10-20 mcg IV with 5-10 min lockout. Transdermal: 12-100 mcg/h patch every 72 hours; start at 25 mcg/h in opioid-naive patients.
Fentanyl 50-100 mcg IV and droperidol 2.5-5 mg IV, administered slowly over 1-2 minutes, repeated every 60 minutes as needed for breakthrough pain or sedation.

3–7 hours (terminal elimination half-life; prolonged in elderly, hepatic impairment, or with continuous infusion due to redistribution).
Fentanyl: 3-4 hours (terminal elimination half-life); prolonged in elderly and hepatic impairment. Droperidol: 2.2-2.5 hours (terminal elimination half-life).
Renal (primarily as metabolites, <10% unchanged; ~75% total metabolites in urine), fecal (~9% total metabolites).
Fentanyl: primarily renal (75% as metabolites, <10% unchanged), with about 9% excreted in feces. Droperidol: renal (75% as metabolites, <1% unchanged), about 22% in feces.
