Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis and thereby decreasing inflammation, pain, and fever.
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.
200–400 mg orally every 4–6 hours as needed; maximum 1200 mg/day.
1 tablet (ibuprofen 200 mg/phenylephrine HCl 10 mg) orally every 4-6 hours as needed, not to exceed 6 tablets per 24 hours.

1.8 to 2.5 hours. The short half-life supports dosing every 4 to 6 hours for acute pain and fever.
Ibuprofen: 2-4 hours (prolonged in overdose or hepatic impairment). Phenylephrine: 2-3 hours (clinical activity may persist longer due to vasoconstrictive effects).
Renal excretion of metabolites and conjugates accounts for approximately 90% of an administered dose. Less than 1% is excreted unchanged. Biliary/fecal elimination accounts for about 10%.
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.
