ADVIL COLD AND SINUS vs NAPROSYN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, leading to analgesic, anti-inflammatory, and antipyretic effects. Pseudoephedrine is a sympathomimetic amine that directly acts on alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction and reducing nasal congestion.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis. This results in decreased inflammation, pain, and fever.
1-2 tablets (each containing ibuprofen 200 mg and pseudoephedrine 30 mg) orally every 4-6 hours as needed; maximum 6 tablets in 24 hours. Do not exceed 1200 mg ibuprofen and 180 mg pseudoephedrine per day.
250-500 mg orally twice daily; maximum 1500 mg/day. For extended-release: 750-1000 mg orally once daily.

Ibuprofen: 2-4 hours (terminal; rapid elimination, no accumulation with intermittent use). Pseudoephedrine: 4-8 hours (terminal; prolonged in alkaline urine, up to 16 hours at pH 8).
Terminal elimination half-life is 12-17 hours. This long half-life allows twice-daily dosing, but may lead to drug accumulation in elderly or renally impaired patients.
Renal excretion of unchanged drug and metabolites: ibuprofen ~45-60% (primarily as conjugated metabolites, <10% unchanged), pseudoephedrine ~70-90% unchanged. Biliary/fecal elimination accounts for <10% for both components.
Renal excretion of conjugated metabolites accounts for approximately 95% of a dose, with 1-2% as unchanged naproxen. Fecal excretion is minimal (<5%).
