ADVIL ALLERGY AND CONGESTION RELIEF vs ADVIL LIQUI-GELS
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), reducing prostaglandin synthesis, which mediates inflammation, pain, and fever. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis and thereby decreasing inflammation, pain, and fever.
Ibuprofen 200 mg and pseudoephedrine HCl 30 mg per tablet. Usual adult dose: 1-2 tablets orally every 4-6 hours as needed, not to exceed 6 tablets in 24 hours.
200–400 mg orally every 4–6 hours as needed; maximum 1200 mg/day.

Ibuprofen: 2-4 hours; pseudoephedrine: 5-8 hours. Shorter half-life requires frequent dosing for sustained relief.
1.8 to 2.5 hours. The short half-life supports dosing every 4 to 6 hours for acute pain and fever.
Renal excretion of unchanged drug and metabolites; approximately 1% excreted unchanged (pseudoephedrine) and 15% (ibuprofen). Biliary/fecal elimination accounts for <5%.
Renal excretion of metabolites and conjugates accounts for approximately 90% of an administered dose. Less than 1% is excreted unchanged. Biliary/fecal elimination accounts for about 10%.
