MELOXICAM vs ZORVOLEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective inhibitor of cyclooxygenase-2 (COX-2), reducing prostaglandin synthesis and inflammation.
ZORVOLEX (diclofenac) is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX) enzymes, primarily COX-2, reducing the synthesis of prostaglandins, which are mediators of inflammation, pain, and fever.
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.
50 mg orally every 8 hours or 100 mg orally every 12 hours; maximum 200 mg/day.

Terminal elimination half-life: 15–20 hours. Clinical context: Allows once-daily dosing; steady-state achieved in 3–5 days.
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 of the dual-release formulation is approximately 6-7 hours. Clinical context: Allows twice-daily dosing for sustained analgesic effect.
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).
Renal excretion of metabolites and conjugates accounts for approximately 50% of the dose, with biliary/fecal elimination of the remainder. Less than 5% is excreted unchanged in urine.
