CLOPRA vs TRANSDERM SCOP
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.
Competitive antagonist at muscarinic acetylcholine receptors (M1, M2, M3 subtypes) in the vestibular system, gastrointestinal tract, and central nervous system, inhibiting vagal nerve activity and preventing motion-induced nausea and vomiting.
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.
One transdermal patch (1 mg/72 hours) applied to the hairless area behind the ear at least 4 hours before anticipated exposure; replace every 72 hours as needed.

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 6-8 hours (prolonged in renal impairment; up to 20 hours in severe CKD)
The terminal elimination half-life of scopolamine is approximately 9.5 hours (range 6-12 hours) following transdermal administration. In elderly patients, half-life may be prolonged to up to 20 hours.
Renal (50-70% as unchanged drug and metabolites); fecal (20-30%); biliary (minor ~5%)
Scopolamine is extensively metabolized; about 50% of a dose is excreted renally as metabolites and unchanged drug, with less than 10% excreted unchanged in urine. Biliary/fecal excretion accounts for approximately 30-40% of the dose.
