ALEVE-D SINUS & COLD vs BUTAZOLIDIN
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 (COX-1 and COX-2), thereby reducing prostaglandin synthesis. Also has uricosuric effect at higher doses.
Naproxen 220 mg (as naproxen sodium) and pseudoephedrine HCl 120 mg orally every 12 hours; maximum 2 doses per 24 hours.
Butazolidin (phenylbutazone) is typically administered orally at 100-200 mg 3 times daily with meals, not to exceed 600 mg/day. Initial loading dose of 400 mg may be given on day 1, followed by 300-400 mg/day in divided doses. Duration should be limited to 7-10 days.

Naproxen: 12-17 hours (clinical: twice daily dosing); pseudoephedrine: 4-6 hours (clinical: every 4-6 hours).
Terminal half-life: 50-100 hours (prolonged in elderly or hepatic/renal impairment; accumulation risk evident within 5-7 days).
Renal elimination: naproxen ~95% (mostly as unconjugated naproxen and 6-O-desmethyl naproxen), pseudoephedrine ~70-90% unchanged. Biliary/fecal: minor (<5% for each).
Primarily renal: ~60% as unchanged drug and glucuronide conjugates; biliary/fecal: ~40% (enterohepatic circulation).
