ADVIL DUAL ACTION WITH ACETAMINOPHEN vs ALEVE-D SINUS & COLD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. Acetaminophen is an analgesic and antipyretic whose mechanism is not fully understood but involves inhibition of cyclooxygenase in the central nervous system and modulation of the endocannabinoid system.
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.
One caplet (ibuprofen 250 mg and acetaminophen 500 mg) orally every 8 hours while symptoms persist; maximum: 3 caplets per day.
Naproxen 220 mg (as naproxen sodium) and pseudoephedrine HCl 120 mg orally every 12 hours; maximum 2 doses per 24 hours.

Ibuprofen: 2-4 hours; Acetaminophen: 2-3 hours. Clinical context: Short half-lives require dosing every 6-8 hours. Extended half-life in overdose (acetaminophen >4 hours indicates toxicity).
Naproxen: 12-17 hours (clinical: twice daily dosing); pseudoephedrine: 4-6 hours (clinical: every 4-6 hours).
Ibuprofen: renal (90% as metabolites and conjugates, <10% unchanged); Acetaminophen: renal (85% as sulfate and glucuronide conjugates, 4% unchanged, 9% as cysteine and mercapturic acid conjugates; minor biliary).
Renal elimination: naproxen ~95% (mostly as unconjugated naproxen and 6-O-desmethyl naproxen), pseudoephedrine ~70-90% unchanged. Biliary/fecal: minor (<5% for each).
