APREPITANT vs CLOPRA-"YELLOW"
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective high-affinity antagonist of the human substance P/neurokinin 1 (NK1) receptor, inhibiting emesis by blocking the binding of substance P in the central nervous system.
Clopra (metoclopramide) is a dopamine D2 receptor antagonist and, at higher doses, a serotonin 5-HT4 receptor agonist, which enhances gastrointestinal motility and accelerates gastric emptying. It also has central antiemetic effects via D2 blockade in the chemoreceptor trigger zone.
125 mg orally once on day 1, then 80 mg orally once on days 2 and 3 of a 3-day chemotherapy regimen, given 1 hour before chemotherapy. Alternatively, a single 165 mg oral dose for prevention of postoperative nausea and vomiting.
Adult: 25-50 mg orally 3-4 times daily; maximum 200 mg/day. For severe pain: 50-100 mg intramuscularly every 4-6 hours; maximum 300 mg/day.

Terminal elimination half-life is approximately 9 to 13 hours in adults, allowing once-daily dosing. In pediatric patients, half-life may be shorter (about 5-6 hours).
8-12 hours in normal renal function; prolonged to 24-48 hours in severe renal impairment (CrCl <30 mL/min)
Aprepitant is eliminated primarily by metabolism; less than 5% is excreted unchanged in urine or feces. Approximately 50% of a dose is recovered in feces (mostly metabolites) and 10% in urine.
Renal: 70% unchanged, Biliary/Fecal: 20% as metabolites, 10% other
