Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Desloratadine is a long-acting tricyclic histamine antagonist with selective peripheral H1-receptor antagonist activity. Loratadine is a long-acting antihistamine that selectively antagonizes peripheral H1-receptors.
EVALOSE is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity by blocking the reuptake of serotonin at the presynaptic neuron, thereby increasing serotonin levels in the synaptic cleft.
1 tablet (5 mg desloratadine/120 mg pseudoephedrine) orally once daily
Adults: 1-2 tablets (5-10 mg) orally once daily, adjusted to maximum 20 mg/day.

Desloratadine: terminal t1/2 27 hours (range 20-50h) supporting once-daily dosing. Pseudoephedrine: t1/2 5-8 hours (up to 16h in alkaline urine).
Terminal elimination half-life is 12 hours (range 10-14 h); clinically significant for once-daily dosing in most patients with normal renal function; extend dosing interval in renal impairment
Desloratadine: ~87% excreted as metabolites (41% urine, 43% feces), <2% unchanged. Pseudoephedrine: ~70-90% excreted unchanged in urine.
Renal: 70% unchanged; Biliary/Fecal: 20% as metabolites; 10% other
