ADVIL COLD AND SINUS 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, leading to analgesic, anti-inflammatory, and antipyretic effects. Pseudoephedrine is a sympathomimetic amine that directly acts on alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction and reducing nasal congestion.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis and thereby decreasing inflammation, pain, and fever.
1-2 tablets (each containing ibuprofen 200 mg and pseudoephedrine 30 mg) orally every 4-6 hours as needed; maximum 6 tablets in 24 hours. Do not exceed 1200 mg ibuprofen and 180 mg pseudoephedrine per day.
200–400 mg orally every 4–6 hours as needed; maximum 1200 mg/day.

Ibuprofen: 2-4 hours (terminal; rapid elimination, no accumulation with intermittent use). Pseudoephedrine: 4-8 hours (terminal; prolonged in alkaline urine, up to 16 hours at pH 8).
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: ibuprofen ~45-60% (primarily as conjugated metabolites, <10% unchanged), pseudoephedrine ~70-90% unchanged. Biliary/fecal elimination accounts for <10% for both components.
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%.
