ADVIL CONGESTION RELIEF vs CAMBIA
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) enzymes, reducing prostaglandin synthesis and thereby alleviating 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.
50 mg orally once daily as needed for acute migraine, maximum 1 packet (50 mg) per 24 hours.

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 of diclofenac (active moiety) is approximately 1.9-2.1 hours. The clinical context: short half-life supports twice-daily dosing for acute pain.
Renal: ~90% as unchanged drug and metabolites (ibuprofen: <10% unchanged, pseudoephedrine: 43-96% unchanged). Biliary/fecal: minimal (<5%).
Approximately 50% of a dose is excreted in urine primarily as metabolites and conjugates, with less than 10% as unchanged drug. Biliary/fecal excretion accounts for about 40%.
