Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
ONMEL (omacetaxine mepesuccinate) inhibits protein synthesis by binding to the 80S ribosome and interfering with chain elongation, leading to apoptosis in leukemic cells.
Oral: 300-600 mg every 6-8 hours as needed; maximum 3200 mg/day.

Terminal elimination half-life is 2–3 hours; may be prolonged in elderly and patients with hepatic impairment.
Terminal half-life 40–60 hours (mean 50 hours); allows once-daily dosing for systemic antifungal therapy.
Primarily renal; approximately 90% of a dose is excreted in urine as glucuronide conjugates and unchanged drug; <2% excreted in feces.
Primarily hepatic metabolism via CYP3A4; <1% excreted unchanged in urine; >90% eliminated as metabolites in bile and feces.
