ALEVE-D SINUS & COLD vs DIFLUNISAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant via alpha-adrenergic receptor agonism in the nasal mucosa.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
Naproxen 220 mg (as naproxen sodium) and pseudoephedrine HCl 120 mg orally every 12 hours; maximum 2 doses per 24 hours.
500 mg to 1000 mg orally initially, then 250 mg to 500 mg every 8 to 12 hours. Maximum daily dose: 1500 mg.

Naproxen: 12-17 hours (clinical: twice daily dosing); pseudoephedrine: 4-6 hours (clinical: every 4-6 hours).
8-12 hours (prolonged in renal impairment; clinical context: permits twice-daily dosing)
Renal elimination: naproxen ~95% (mostly as unconjugated naproxen and 6-O-desmethyl naproxen), pseudoephedrine ~70-90% unchanged. Biliary/fecal: minor (<5% for each).
Renal (90% as glucuronide conjugates, <5% unchanged); biliary/fecal (<10%)
