Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis, resulting in anti-inflammatory, analgesic, and antipyretic effects.
Selective cyclooxygenase-2 (COX-2) inhibitor, reducing prostaglandin synthesis involved in inflammation, pain, and fever.
200-800 mg orally every 6-8 hours as needed; maximum daily dose 3200 mg.
50-100 mg orally twice daily, or 100-200 mg rectally once daily (suppository).

Terminal elimination half-life is approximately 2-4 hours; in elderly or patients with hepatic impairment, half-life may be prolonged to 6-8 hours.
Terminal elimination half-life: 12–18 hours in dogs at recommended doses. Clinical context: Supports twice-daily dosing; longer half-life in some breeds may require dose adjustment.
Renal excretion of conjugated metabolites (75-85%), with less than 10% excreted unchanged; biliary/fecal elimination accounts for less than 10%.
Primarily hepatic metabolism (oxidation, conjugation) with ~70% of metabolites excreted in urine and ~30% in feces via biliary elimination. Less than 5% excreted unchanged.
