ADVIL ALLERGY AND CONGESTION RELIEF vs EC-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, which mediates inflammation, pain, and fever. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
Ibuprofen 200 mg and pseudoephedrine HCl 30 mg per tablet. Usual adult dose: 1-2 tablets orally every 4-6 hours as needed, not to exceed 6 tablets in 24 hours.
500-1000 mg orally twice daily; maximum 1500 mg/day.

Ibuprofen: 2-4 hours; pseudoephedrine: 5-8 hours. Shorter half-life requires frequent dosing for sustained relief.
Terminal elimination half-life 12-17 hours (mean 14 hours); prolonged in elderly and renal impairment
Renal excretion of unchanged drug and metabolites; approximately 1% excreted unchanged (pseudoephedrine) and 15% (ibuprofen). Biliary/fecal elimination accounts for <5%.
Renal (95%) as unchanged drug (10%) and conjugated metabolites (60%) and other metabolites (25%); biliary/fecal (5%)
