ALEVE-D SINUS & COLD vs CLARINEX D 24 HOUR
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.
Desloratadine is a long-acting tricyclic histamine antagonist with selective peripheral H1-receptor antagonist activity. Loratadine is a long-acting antihistamine that selectively antagonizes peripheral H1-receptors.
Naproxen 220 mg (as naproxen sodium) and pseudoephedrine HCl 120 mg orally every 12 hours; maximum 2 doses per 24 hours.
1 tablet (5 mg desloratadine/120 mg pseudoephedrine) orally once daily

Naproxen: 12-17 hours (clinical: twice daily dosing); pseudoephedrine: 4-6 hours (clinical: every 4-6 hours).
Desloratadine: terminal t1/2 27 hours (range 20-50h) supporting once-daily dosing. Pseudoephedrine: t1/2 5-8 hours (up to 16h in alkaline urine).
Renal elimination: naproxen ~95% (mostly as unconjugated naproxen and 6-O-desmethyl naproxen), pseudoephedrine ~70-90% unchanged. Biliary/fecal: minor (<5% for each).
Desloratadine: ~87% excreted as metabolites (41% urine, 43% feces), <2% unchanged. Pseudoephedrine: ~70-90% excreted unchanged in urine.
