CLARITIN HIVES RELIEF REDITAB vs DESLORATADINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective inverse agonist of peripheral histamine H1 receptors, inhibiting histamine release from mast cells and basophils.
Desloratadine is a long-acting tricyclic histamine antagonist selective for the H1 receptor, inhibiting histamine release from mast cells and basophils. It reduces allergic inflammation by decreasing cytokine and chemokine release.

Terminal elimination half-life of loratadine is 8.4 hours (range 3–20 hours); for its active metabolite descarboethoxyloratadine, it is 24.9 hours (range 8.8–45 hours). Clinical context: Steady-state concentrations are achieved by day 5.
