CLOPRA vs COMPAZINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clopra (metoclopramide) is a dopamine D2 receptor antagonist and a 5-HT4 receptor agonist, enhancing gastrointestinal motility and having antiemetic effects via central and peripheral actions.
Dopamine D2 receptor antagonist in the chemoreceptor trigger zone; also blocks alpha-1 adrenergic, histamine H1, and muscarinic M1 receptors.
Clopra (metoclopramide) 10 mg orally or intramuscularly 30 minutes before meals and at bedtime; maximum 30 mg/day. For intravenous administration, give 10 mg over 1-2 minutes.
5-10 mg IM/IV every 3-4 hours as needed; or 25 mg PO/PR twice daily for severe nausea/vomiting.

Terminal elimination half-life 6-8 hours (prolonged in renal impairment; up to 20 hours in severe CKD)
Clinical Note
moderateMetoclopramide + Haloperidol
"The risk or severity of adverse effects can be increased when Metoclopramide is combined with Haloperidol."
Clinical Note
moderateMetoclopramide + Quinagolide
"The therapeutic efficacy of Quinagolide can be decreased when used in combination with Metoclopramide."
Clinical Note
moderateMetoclopramide + Cyclosporine
"Metoclopramide can cause an increase in the absorption of Cyclosporine resulting in an increased serum concentration and potentially a worsening of adverse effects."
Clinical Note
moderateTerminal elimination half-life is approximately 23 hours (range 15-30 hours) after oral or intramuscular administration. Clinical context: requires multiple daily dosing for steady state.
Renal (50-70% as unchanged drug and metabolites); fecal (20-30%); biliary (minor ~5%)
Renal (approximately 70% as metabolites, <1% unchanged), biliary/fecal (approximately 30%).

Metoclopramide + Clotrimazole
"The metabolism of Clotrimazole can be decreased when combined with Metoclopramide."
