EC-NAPROSYN 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-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
Selective inhibitor of cyclooxygenase-2 (COX-2), reducing prostaglandin synthesis and inflammation.
500-1000 mg orally twice daily; maximum 1500 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 12-17 hours (mean 14 hours); prolonged in elderly and renal impairment
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 (95%) as unchanged drug (10%) and conjugated metabolites (60%) and other metabolites (25%); biliary/fecal (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).
