ANAPROX DS vs MELOXICAM
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.
Selective inhibitor of cyclooxygenase-2 (COX-2), reducing prostaglandin synthesis and inflammation.
550 mg orally every 8 to 12 hours; maximum 1375 mg/day.
7.5-15 mg orally once daily; maximum 15 mg/day. For osteoarthritis, rheumatoid arthritis: 7.5 mg once daily, may increase to 15 mg/day if needed. For juvenile rheumatoid arthritis, weight-based dosing.

Terminal elimination half-life is approximately 12–17 hours (mean ~14 hours), allowing twice-daily dosing. Steady-state is achieved after 4–5 doses.
Clinical Note
moderateMeloxicam + Gatifloxacin
"Meloxicam may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateMeloxicam + Rosoxacin
"Meloxicam may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateMeloxicam + Levofloxacin
"Meloxicam may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderateMeloxicam + Trovafloxacin
"Meloxicam may increase the neuroexcitatory activities of Trovafloxacin."
Terminal elimination half-life: 15–20 hours. Clinical context: Allows once-daily dosing; steady-state achieved in 3–5 days.
Renal elimination of naproxen and its metabolites accounts for approximately 95% of the dose, with about 60% as unchanged drug and 40% as conjugated or hydroxylated metabolites. Biliary/fecal excretion is negligible (<5%).
Approximately 50% renal excretion of unchanged drug and metabolites; 50% fecal excretion via bile. Renal elimination accounts for ~5% unchanged meloxicam; the remainder as metabolites (primarily oxidative and glucuronide conjugates).
