Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine at H1 receptor sites, suppressing histamine-induced vasodilation, increased capillary permeability, and bronchoconstriction.
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.
4 mg orally every 4-6 hours, not to exceed 24 mg/day. Alternatively, extended-release: 12 mg every 12 hours.
1 tablet (5 mg desloratadine / 120 mg pseudoephedrine) orally every 12 hours.

Terminal half-life 22-25 hours; prolonged in hepatic impairment or elderly (up to 40 hours).
Desloratadine: 27 hours (terminal), allows once-daily dosing; pseudoephedrine: 4-6 hours (prolonged in alkaline urine).
Renal (85-90% as metabolites, 5-10% unchanged); biliary/fecal <5%.
Desloratadine: 40.2% renal (unchanged and metabolites), 41.7% fecal; pseudoephedrine: 70-90% renal (unchanged).
