Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, which mediates pain, inflammation, and fever.
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.

Terminal elimination half-life: 10-20 hours; context: allows twice-daily or once-daily dosing for chronic pain or inflammation.
Terminal elimination half-life of the dual-release formulation is approximately 6-7 hours. Clinical context: Allows twice-daily dosing for sustained analgesic effect.
Renal: 50-60% as metabolites and conjugates; biliary/fecal: ~5%; remainder uncharacterized.
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.
