DROPERIDOL vs NAVANE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Droperidol is a butyrophenone antipsychotic that acts primarily as a dopamine D2 receptor antagonist. It also exhibits antiemetic effects via blockade of dopamine D2 receptors in the chemoreceptor trigger zone. Additionally, it has alpha-adrenergic blocking properties and can prolong the QT interval by blocking cardiac potassium channels (hERG).
Thioxanthene neuroleptic; blocks postsynaptic dopamine D1 and D2 receptors in the brain; also exhibits anticholinergic, alpha-adrenergic blocking, and sedative effects.
2.5-10 mg IV/IM every 3-4 hours as needed for nausea and vomiting; for agitation or psychosis in perioperative settings: 0.625-1.25 mg IV/IM, may repeat every 6 hours.
Oral: 10-20 mg three times daily; maximum 160 mg/day. IM (acute): 5-10 mg every 4-6 hours; maximum 30 mg/day.

Clinical Note
moderateDroperidol + Norfloxacin
"Droperidol may increase the QTc-prolonging activities of Norfloxacin."
Clinical Note
moderateDroperidol + Ibandronate
"Droperidol may increase the QTc-prolonging activities of Ibandronate."
Clinical Note
moderateDroperidol + Indapamide
"Droperidol may increase the QTc-prolonging activities of Indapamide."
Clinical Note
moderateDroperidol + Methylphenidate
"The risk or severity of adverse effects can be increased when Droperidol is combined with Methylphenidate."
Terminal elimination half-life: 2.3 hours (range 1.5–4.7 hours). Clinical context: Short half-life allows rapid titration but requires repeated dosing or continuous infusion for sustained effect; accumulation with hepatic impairment.
Terminal elimination half-life is approximately 20-24 hours, allowing for once-daily dosing. Steady-state reached in 4-5 days.
Renal (75% as metabolites, <1% unchanged); fecal (22%); biliary excretion contributes to enterohepatic circulation.
Primarily hepatic metabolism; approximately 20-30% excreted renally as metabolites, <1% unchanged. Biliary/fecal excretion accounts for ~50% of metabolites.
