DYCLOPRO vs KETOROLAC TROMETHAMINE AND PHENYLEPHRINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Diclofenac epolamine inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and consequent inflammation, pain, and fever.
Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis. Phenylephrine is a selective alpha-1 adrenergic receptor agonist, causing vasoconstriction.
50 mg intravenously every 8 hours
Ophthalmic: 1 drop of the combination (ketorolac tromethamine 0.45% and phenylephrine hydrochloride 1%) into the operative eye three times daily, beginning 1 day prior to surgery and continuing on the day of surgery and for 2 weeks postoperatively.

Terminal elimination half-life is approximately 2-4 hours in adults with normal renal function; may be prolonged in renal impairment (up to 8-12 hours).
Ketorolac: 2.4-8.6 hours (mean 5.3 hours) in young adults; prolonged in elderly (up to 13.9 hours) and renal impairment. Phenylephrine: 2-3 hours.
Primarily renal (approximately 70% as unchanged drug and metabolites); biliary/fecal excretion accounts for about 30%.
Ketorolac: ~92% renal (60% as unchanged drug, 32% as metabolites), 6% fecal. Phenylephrine: primarily renal as metabolites (sulfate conjugates) with <1% unchanged.
