ALEVE-D SINUS & COLD vs PROPOXYPHENE HYDROCHLORIDE W/ ASPIRIN AND CAFFEINE
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.
Propoxyphene is a centrally acting opioid analgesic that binds to mu-opioid receptors. Aspirin inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis. Caffeine is a CNS stimulant that may enhance analgesia.
Naproxen 220 mg (as naproxen sodium) and pseudoephedrine HCl 120 mg orally every 12 hours; maximum 2 doses per 24 hours.
1-2 capsules orally every 4-6 hours as needed; maximum 6 capsules per day. Each capsule contains propoxyphene hydrochloride 65 mg, aspirin 325 mg, and caffeine 32.4 mg.

Naproxen: 12-17 hours (clinical: twice daily dosing); pseudoephedrine: 4-6 hours (clinical: every 4-6 hours).
Propoxyphene: 6-12 hours (up to 36 hours in overdose); norpropoxyphene: 30-36 hours. Aspirin: 2-3 hours for low doses, up to 15-30 hours in overdose. Caffeine: 3-6 hours; prolonged in liver disease.
Renal elimination: naproxen ~95% (mostly as unconjugated naproxen and 6-O-desmethyl naproxen), pseudoephedrine ~70-90% unchanged. Biliary/fecal: minor (<5% for each).
Renal elimination of propoxyphene and its metabolites (mainly norpropoxyphene) accounts for approximately 70-90% of the dose; fecal excretion is minimal (<10%). Aspirin is renally eliminated as salicylates (75-90% as conjugates, 10% free), while caffeine is primarily metabolized and its metabolites are excreted renally.
