DIFLUNISAL vs KETOROLAC TROMETHAMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
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.
500 mg to 1000 mg orally initially, then 250 mg to 500 mg every 8 to 12 hours. Maximum daily dose: 1500 mg.
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).

8-12 hours (prolonged in renal impairment; clinical context: permits twice-daily dosing)
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 (90% as glucuronide conjugates, <5% unchanged); biliary/fecal (<10%)
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.
