Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective COX-1 and COX-2 inhibitor, reducing prostaglandin synthesis.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby decreasing inflammation, pain, and fever.
Ibuprofen (Motrin) 200-800 mg orally every 6-8 hours as needed; maximum 3200 mg/day for acute pain, and 2400 mg/day for chronic use.
Intranasal: 31.5 mg (1 spray) in one nostril, may repeat after 30 minutes; maximum 63 mg (2 sprays) per dose. Subsequent doses every 6-8 hours as needed; maximum 126 mg (4 sprays) per day.

Terminal elimination half-life approximately 2-4 hours in adults with normal renal function; prolonged in elderly and patients with renal impairment (up to 6-8 hours). No significant accumulation occurs with regular dosing.
Terminal elimination half-life is 5-6 hours in adults with normal renal function; may be prolonged to 13-14 hours in elderly patients and 15-20 hours in patients with renal impairment.
Renal excretion of conjugated metabolites (approximately 70-80% as glucuronide and sulfate conjugates); less than 10% excreted unchanged. Biliary/fecal elimination accounts for about 10-20%.
Renal excretion of unchanged drug and metabolites; after intravenous administration, approximately 92% of the dose is recovered in urine (50% as unchanged ketorolac, 40% as glucuronide conjugates) and 6% in feces.
