ADVIL ALLERGY SINUS vs SUDAFED 12 HOUR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Pseudoephedrine is a sympathomimetic amine that directly stimulates alpha-adrenergic receptors, causing vasoconstriction of nasal mucosa and sinus vessels. Chlorpheniramine is an alkylamine antihistamine that competitively antagonizes histamine H1 receptors, reducing allergic symptoms. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, decreasing prostaglandin synthesis and reducing pain, fever, and inflammation.
Pseudoephedrine is a sympathomimetic amine that acts as an agonist at alpha-1 and alpha-2 adrenergic receptors, causing vasoconstriction of nasal mucosa and reducing nasal congestion.
1-2 tablets (each tablet contains ibuprofen 200 mg and pseudoephedrine HCl 30 mg) orally every 4-6 hours as needed; maximum 6 tablets per day.
120 mg orally every 12 hours, extended-release tablets. Maximum 240 mg per day.

2–4 hours (pseudoephedrine: 5–8 hours); clinical context: requires q4-6h dosing for pain/fever, q6-8h for congestion
8-10 hours in adults with normal renal function; prolonged to 19-24 hours in renal impairment (CrCl <30 mL/min); shorter in children (3-4 hours)
Renal (90% as conjugates and metabolites; <10% unchanged); biliary/fecal (<5%)
Renal: 74-95% as unchanged drug; 1-4% as active metabolite (norpsuedoephedrine); biliary/fecal: minimal (<1%)
