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 COX-1 and COX-2 inhibitor, reducing prostaglandin synthesis via inhibition of cyclooxygenase, leading to anti-inflammatory, analgesic, and antipyretic effects.
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.
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.

Ibuprofen: 2-4 hours; pseudoephedrine: 5-8 hours. Shorter half-life requires frequent dosing for sustained relief.
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.
Renal excretion of unchanged drug and metabolites; approximately 1% excreted unchanged (pseudoephedrine) and 15% (ibuprofen). Biliary/fecal elimination accounts for <5%.
Approximately 65% renal as glucuronide conjugates and inactive metabolites, ~20% biliary/fecal. Less than 1% unchanged in urine.
