NAPROXEN vs TAB-PROFEN
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-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing the synthesis of prostaglandins involved in inflammation, pain, and fever.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor; reduces prostaglandin synthesis.
250-500 mg orally twice daily; maximum 1.5 g/day. For extended-release: 750-1000 mg orally once daily.
400-800 mg orally every 6-8 hours as needed; maximum 3200 mg/day.

Terminal elimination half-life 12-17 hours (mean 14 hours); permits twice-daily dosing. Half-life prolonged in elderly and hepatic impairment.
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."
The terminal elimination half-life is 2-4 hours in adults with normal renal function. In elderly patients or those with renal impairment, half-life may be prolonged up to 8-12 hours, requiring dose adjustment.
Primarily renal (95% as unchanged naproxen and 6-O-desmethylnaproxen); <5% fecal via biliary excretion.
Renal excretion of unchanged drug accounts for approximately 70-90% of the administered dose, with the remainder eliminated as glucuronide conjugates in urine. Biliary/fecal elimination is minimal (<5%).
