ANAPROX vs OXAPROZIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
Oxaprozin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis, which results in anti-inflammatory, analgesic, and antipyretic effects.
250-500 mg orally twice daily; maximum 1.5 g/day; for extended-release: 375-750 mg orally twice daily
600-1200 mg orally once daily; maximum 1800 mg/day.

Terminal elimination half-life 12-17 hours; prolonged in elderly (up to 20 hours) and in renal impairment.
Clinical Note
moderateOxaprozin + Gatifloxacin
"Oxaprozin may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateOxaprozin + Rosoxacin
"Oxaprozin may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateOxaprozin + Levofloxacin
"Oxaprozin may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderateOxaprozin + Trovafloxacin
"Oxaprozin may increase the neuroexcitatory activities of Trovafloxacin."
Terminal elimination half-life is approximately 50–60 hours in healthy adults; clinical context: once-daily dosing achieves steady-state in 7–10 days.
Renal excretion of metabolites (95%) and unchanged drug (<5%); biliary/fecal elimination minor (<5%).
Primarily hepatic metabolism (glucuronidation and hydroxylation) with renal excretion of metabolites; less than 1% excreted unchanged in urine; fecal elimination accounts for ~20%.
