COXANTO vs KETOROLAC TROMETHAMINE AND PHENYLEPHRINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective inhibitor of soluble epoxide hydrolase (sEH), increasing levels of epoxyeicosatrienoic acids (EETs), which have vasodilatory, anti-inflammatory, and antifibrotic effects.
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.
1 g intravenous every 6 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: 12-15 hours (prolonged to 24-30 hours in moderate-to-severe renal impairment, requiring dose adjustment)
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.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
Ketorolac: ~92% renal (60% as unchanged drug, 32% as metabolites), 6% fecal. Phenylephrine: primarily renal as metabolites (sulfate conjugates) with <1% unchanged.
