OXAPROZIN vs ZIPSOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that selectively inhibits cyclooxygenase-2 (COX-2), reducing prostaglandin synthesis involved in inflammation, pain, and fever. It has no significant inhibition of COX-1 at therapeutic doses.
600-1200 mg orally once daily; maximum 1800 mg/day.
50 mg orally three times daily

Terminal elimination half-life is approximately 50–60 hours in healthy adults; clinical context: once-daily dosing achieves steady-state in 7–10 days.
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."
2-4 hours (terminal); clinical context: short half-life necessitates frequent dosing for sustained relief; prolonged in hepatic impairment
Primarily hepatic metabolism (glucuronidation and hydroxylation) with renal excretion of metabolites; less than 1% excreted unchanged in urine; fecal elimination accounts for ~20%.
Renal: ~60% unchanged; biliary/fecal: ~30% as metabolites; remainder as glucuronide conjugates
