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.
Desloratadine is a long-acting tricyclic histamine antagonist selective for H1-receptor with additional anti-inflammatory properties. Pseudoephedrine is a sympathomimetic amine that acts as a vasoconstrictor via alpha-adrenergic receptors.
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.
1 tablet (5 mg desloratadine / 120 mg pseudoephedrine) orally every 12 hours.

Ibuprofen: 2-4 hours; pseudoephedrine: 5-8 hours. Shorter half-life requires frequent dosing for sustained relief.
Desloratadine: 27 hours (terminal), allows once-daily dosing; pseudoephedrine: 4-6 hours (prolonged in alkaline urine).
Renal excretion of unchanged drug and metabolites; approximately 1% excreted unchanged (pseudoephedrine) and 15% (ibuprofen). Biliary/fecal elimination accounts for <5%.
Desloratadine: 40.2% renal (unchanged and metabolites), 41.7% fecal; pseudoephedrine: 70-90% renal (unchanged).
