IBUPROFEN AND PHENYLEPHRINE HYDROCHLORIDE vs INDOCIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. Phenylephrine is a selective alpha-1 adrenergic receptor agonist, causing vasoconstriction.
Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever. It also decreases renal blood flow and may cause ductus arteriosus closure.
1 tablet (ibuprofen 200 mg/phenylephrine HCl 10 mg) orally every 4-6 hours as needed, not to exceed 6 tablets per 24 hours.
25 mg orally 2-3 times daily; maximum 200 mg/day. Intravenous: 0.5-1 mg/kg as single dose for ductus arteriosus closure.

Ibuprofen: 2-4 hours (prolonged in overdose or hepatic impairment). Phenylephrine: 2-3 hours (clinical activity may persist longer due to vasoconstrictive effects).
Terminal elimination half-life approximately 4.5 hours (range 2.6–11.2 hours); prolonged in elderly and patients with hepatic impairment.
Ibuprofen: Renal elimination of metabolites (90%) and unchanged drug (1-10%); biliary/fecal excretion minor. Phenylephrine: Renal elimination (80-85% as inactive metabolites, 2-3% unchanged); biliary/fecal negligible.
Renal (60% as unchanged drug and glucuronide conjugates), biliary/fecal (33% via enterohepatic circulation).
