ALEVE-D SINUS & COLD vs TRIPHED
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.
Triprolidine is a first-generation antihistamine that competitively antagonizes histamine at H1 receptors, thereby alleviating symptoms of allergic reactions. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction and reducing edema.
Naproxen 220 mg (as naproxen sodium) and pseudoephedrine HCl 120 mg orally every 12 hours; maximum 2 doses per 24 hours.
Adults: Triprolidine 2.5 mg / pseudoephedrine 60 mg orally every 4-6 hours, not to exceed 4 doses in 24 hours.

Naproxen: 12-17 hours (clinical: twice daily dosing); pseudoephedrine: 4-6 hours (clinical: every 4-6 hours).
Terminal elimination half-life is 6-8 hours in adults with normal renal function; clinically, dosing interval adjustments are recommended in renal impairment.
Renal elimination: naproxen ~95% (mostly as unconjugated naproxen and 6-O-desmethyl naproxen), pseudoephedrine ~70-90% unchanged. Biliary/fecal: minor (<5% for each).
Renal excretion of unchanged drug and metabolites accounting for approximately 60-70% of elimination; biliary/fecal elimination accounts for 20-30%.
