ADVIL CONGESTION RELIEF vs LODINE
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
Inhibition of prostaglandin synthesis via cyclooxygenase (COX) inhibition, with selectivity for COX-2 over COX-1.
1 tablet (ibuprofen 200 mg / phenylephrine 10 mg) orally every 4 hours while symptoms persist, not to exceed 6 tablets in 24 hours.
200 to 400 mg orally every 6 to 8 hours as needed; maximum daily dose 1200 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.
Terminal elimination half-life approximately 7.5 hours; in elderly or renal impairment, half-life may be prolonged up to 10 hours, requiring dose adjustment
Renal: ~90% as unchanged drug and metabolites (ibuprofen: <10% unchanged, pseudoephedrine: 43-96% unchanged). Biliary/fecal: minimal (<5%).
Primarily renal (60% as metabolites, <1% unchanged); biliary/fecal (30-35%)
