CHILDREN'S ZYRTEC HIVES vs DESLORATADINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cetirizine is a selective antagonist of peripheral histamine H1 receptors, inhibiting histamine-mediated allergic reactions.
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 is approximately 8-11 hours in healthy adults, allowing twice-daily dosing.
