Category C

PROCHLORPERAZINE

Typical Antipsychotic / Antiemetic

Category A/B

Head-to-Head

Clinical Matrix

Mechanism of Action

Selective 5-HT3 receptor antagonist; blocks serotonin action at vagal nerve terminals and in the chemoreceptor trigger zone, inhibiting emetic reflex.

Prochlorperazine is a phenothiazine antipsychotic that acts as a dopamine D2 receptor antagonist in the chemoreceptor trigger zone (CTZ) and at high doses in the mesolimbic system. It also has anticholinergic and antiemetic effects.

Clinical Dosing

2.5 mg to 5 mg orally once daily, as disintegrating tablet; may increase to 10 mg if needed

5-10 mg IM/IV every 3-4 hours as needed; or 5-10 mg PO 3-4 times daily; or 25 mg PR twice daily. Maximum IM/IV: 40 mg/day; PO: 40 mg/day.

Direct Interaction

None Documented

Half-Life

~1.5–2 hours in normal renal function; prolonged to 10–20 hours in severe renal impairment (CrCl <30 mL/min).

Other Significant Interactions

Clinical Note

moderate

Prochlorperazine + Fluticasone propionate

"The risk or severity of adverse effects can be increased when Prochlorperazine is combined with Fluticasone propionate."

Clinical Note

moderate
