DICLOFENAC SODIUM vs IBUPROHM COLD AND SINUS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective COX-1 and COX-2 inhibitor, reducing prostaglandin synthesis via inhibition of cyclooxygenase, leading to anti-inflammatory, analgesic, and antipyretic effects.
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.
Oral: 50 mg two to three times daily; maximum 150 mg/day. Topical: 1% gel applied four times daily. Rectal: 100 mg suppository once daily.
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 approximately 2 hours (range 1.3–3.1 h). Short half-life requires frequent dosing; no accumulation with normal dosing intervals.
1.8–2.5 hours in adults; prolonged to 3–4 hours in elderly or hepatic impairment due to reduced clearance.
Approximately 65% renal as glucuronide conjugates and inactive metabolites, ~20% biliary/fecal. Less than 1% unchanged in urine.
Renal excretion of unchanged drug and metabolites accounts for >90% of elimination, with approximately 1% excreted as unchanged ibuprofen. Biliary/fecal excretion is <10%.
