IBUPROFEN AND PHENYLEPHRINE HYDROCHLORIDE vs NAPRELAN
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.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, which mediates pain, inflammation, and fever.
1 tablet (ibuprofen 200 mg/phenylephrine HCl 10 mg) orally every 4-6 hours as needed, not to exceed 6 tablets per 24 hours.
750 mg to 1000 mg orally once daily, with or without food.

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: 10-20 hours; context: allows twice-daily or once-daily dosing for chronic pain or inflammation.
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: 50-60% as metabolites and conjugates; biliary/fecal: ~5%; remainder uncharacterized.
