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
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing synthesis of prostaglandins involved in inflammation, pain, and fever.
1 tablet (ibuprofen 200 mg / phenylephrine 10 mg) orally every 4 hours while symptoms persist, not to exceed 6 tablets in 24 hours.
800 mg IV every 8 hours as a 30-minute infusion; alternatively, 400 mg IV every 6 hours. Maximum daily dose: 2400 mg.

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.
2-4 hours (terminal half-life). Clinical context: Requires dosing every 6-8 hours for sustained effect; no accumulation with normal hepatic function.
Renal: ~90% as unchanged drug and metabolites (ibuprofen: <10% unchanged, pseudoephedrine: 43-96% unchanged). Biliary/fecal: minimal (<5%).
Renal (primarily as glucuronide conjugates and inactive metabolites; <10% unchanged). Biliary/fecal elimination is negligible.
