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), thereby reducing prostaglandin synthesis.
Ketorolac tromethamine is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby decreasing pain and inflammation.
200-300 mg orally or rectally twice daily, or 100 mg orally three times daily; maximum 300 mg/day.
10 mg orally every 4-6 hours, not to exceed 40 mg per day; or 15-30 mg intramuscularly or intravenously every 6 hours, not to exceed 120 mg per day (maximum 60 mg for single dose).

Terminal elimination half-life is approximately 3-4 hours. No accumulation occurs with normal dosing; however, in elderly or hepatic impairment, half-life may be prolonged.
Terminal half-life is 5-6 hours in young adults, prolonged to 9-10 hours in elderly patients (≥65 years) and up to 12-15 hours in renal impairment (CrCl <30 mL/min). Context: q6h dosing interval recommended; accumulation risk in elderly/renal impairment.
Renal excretion of metabolites (approximately 95%), with less than 5% excreted unchanged. Fecal elimination accounts for minor amounts.
Primarily renal excretion: ~92% of dose excreted in urine as parent drug (60%) and metabolites (p-hydroxyketorolac, conjugated forms). Fecal excretion accounts for ~6%. Biliary excretion is minimal.
