CLOPRA vs EMEND
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.
Selective substance P/neurokinin 1 (NK1) receptor antagonist, which inhibits the binding of substance P in the emetic pathway.
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.
125 mg orally once 1 hour before chemotherapy; then 80 mg orally once daily on Days 2 and 3.

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
moderate9–13 hours (terminal) in healthy adults; clinically, this supports once-daily dosing. In patients with severe renal impairment (CrCl <30 mL/min), half-life is prolonged to ~16 hours.
Renal (50-70% as unchanged drug and metabolites); fecal (20-30%); biliary (minor ~5%)
Primarily metabolized; ~5% unchanged in urine, ~57% in feces as metabolites, ~32% in urine as metabolites. Renal elimination of parent drug is minimal.

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