Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Irreversibly inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, reducing prostaglandin and thromboxane synthesis, which leads to analgesic, antipyretic, and anti-inflammatory effects.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing the synthesis of prostaglandins involved in inflammation, pain, and fever.
500-1000 mg orally every 4-6 hours as needed; maximum 4000 mg in 24 hours.
250-500 mg orally twice daily; maximum 1.5 g/day. For extended-release: 750-1000 mg orally once daily.

Aspirin half-life is 15-20 minutes due to rapid hydrolysis to salicylate. Salicylate terminal half-life is 2-3 hours at low doses, up to 15-30 hours at high doses or with toxicity. At analgesic doses (600-1000 mg), effective half-life is ~3-4 hours, requiring q4-6h dosing.
Clinical Note
moderateNaproxen + Gatifloxacin
"Naproxen may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateNaproxen + Rosoxacin
"Naproxen may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateNaproxen + Levofloxacin
"Naproxen may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderateNaproxen + Trovafloxacin
"Naproxen may increase the neuroexcitatory activities of Trovafloxacin."
Terminal elimination half-life 12-17 hours (mean 14 hours); permits twice-daily dosing. Half-life prolonged in elderly and hepatic impairment.
Renal excretion of salicylate and its metabolites (salicyluric acid, salicyl phenolic glucuronide, salicyl acyl glucuronide, gentisic acid). Approximately 90% of a dose is excreted renally; 10% via bile/feces. Excretion is dose- and pH-dependent: alkaline urine increases clearance.
Primarily renal (95% as unchanged naproxen and 6-O-desmethylnaproxen); <5% fecal via biliary excretion.
