ANTIVERT vs CLOPRA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antivert (meclizine) is a piperazine H1 histamine receptor antagonist with central anticholinergic and sedative properties. It suppresses the chemoreceptor trigger zone and labyrinthine apparatus, reducing vestibular stimulation and vertigo.
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.
25-100 mg orally daily in divided doses 2-4 times daily; maximum 400 mg/day.
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.

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 35–50 hours in adults; prolonged in renal impairment.
Terminal elimination half-life 6-8 hours (prolonged in renal impairment; up to 20 hours in severe CKD)
Primarily renal (urine) as unchanged drug and metabolites; biliary excretion is minimal. Approximately 80% excreted unchanged in urine.
Renal (50-70% as unchanged drug and metabolites); fecal (20-30%); biliary (minor ~5%)

Antiemetic
Antiemetic/Prokinetic Agent
Metoclopramide + Clotrimazole
"The metabolism of Clotrimazole can be decreased when combined with Metoclopramide."
