ADVIL COLD AND SINUS vs INDOMETHACIN SODIUM
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 inhibition of cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, leading to anti-inflammatory, antipyretic, and analgesic effects.
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.
Intravenous: 0.5 mg/kg every 12 hours or 0.25 mg/kg every 6 hours for patent ductus arteriosus closure in neonates. Oral/immediate-release: 25-50 mg two to three times daily. Extended-release: 75 mg once daily or 75 mg twice daily. Maximum daily dose: 200 mg.

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).
Terminal elimination half-life: 4.5 hours (range 2.6–11.2 hours); half-life may be prolonged in neonates, elderly, and renal impairment
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 (60% as unchanged drug and metabolites, predominantly glucuronide conjugate); fecal (33%, primarily via biliary secretion); <5% unchanged in urine
