ADVIL CONGESTION RELIEF vs ANSAID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ibuprofen: non-selective COX-1/COX-2 inhibitor reducing prostaglandin synthesis; phenylephrine: alpha-1 adrenergic receptor agonist causing vasoconstriction
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), thereby reducing prostaglandin synthesis.
1 tablet (ibuprofen 200 mg / phenylephrine 10 mg) orally every 4 hours while symptoms persist, not to exceed 6 tablets in 24 hours.
200-300 mg orally or rectally twice daily, or 100 mg orally three times daily; maximum 300 mg/day.

Ibuprofen: 2-4 hours (short half-life requires frequent dosing). Pseudoephedrine: 5-8 hours (longer in alkaline urine). Context: Half-life prolonged in renal impairment.
Terminal elimination half-life is approximately 3-4 hours. No accumulation occurs with normal dosing; however, in elderly or hepatic impairment, half-life may be prolonged.
Renal: ~90% as unchanged drug and metabolites (ibuprofen: <10% unchanged, pseudoephedrine: 43-96% unchanged). Biliary/fecal: minimal (<5%).
Renal excretion of metabolites (approximately 95%), with less than 5% excreted unchanged. Fecal elimination accounts for minor amounts.
