DICLOFENAC POTASSIUM vs IBUPROHM COLD AND SINUS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis, which mediates pain, inflammation, and fever.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, leading to anti-inflammatory, analgesic, and antipyretic effects. Pseudoephedrine is a sympathomimetic amine that acts as a vasoconstrictor via alpha-adrenergic receptors in nasal mucosa, reducing nasal congestion.
50 mg orally twice daily or 75 mg orally once daily; maximum 150 mg/day. Alternatively, 75 mg intramuscularly once daily (short-term).
1-2 tablets (each containing ibuprofen 200 mg and pseudoephedrine 30 mg) orally every 4-6 hours as needed; maximum daily dose: 6 tablets (ibuprofen 1200 mg, pseudoephedrine 180 mg).

Terminal elimination half-life is ~1.1 hours (range 0.9–1.6 h). Short half-life supports frequent dosing (e.g., every 6–8 hours) for sustained analgesia.
1.8–2.5 hours in adults; prolonged to 3–4 hours in elderly or hepatic impairment due to reduced clearance.
Approximately 50% of a dose is eliminated via first-pass hepatic metabolism; renal excretion accounts for ~65% of the administered dose as metabolites (<1% unchanged drug); fecal excretion <20%.
Renal excretion of unchanged drug and metabolites accounts for >90% of elimination, with approximately 1% excreted as unchanged ibuprofen. Biliary/fecal excretion is <10%.
