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) enzymes, 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.
400-600 mg orally three times daily; maximum 1.8 g/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 half-life approximately 5-6 hours; clinical context: dosing every 6-8 hours required due to relatively short half-life; steady-state achieved within 24-30 hours.
Renal: ~90% as unchanged drug and metabolites (ibuprofen: <10% unchanged, pseudoephedrine: 43-96% unchanged). Biliary/fecal: minimal (<5%).
Renal (90-95% as unchanged drug and metabolites, primarily glucuronide conjugates); biliary/fecal (minor, <5%).
