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.
Selective histamine H1 receptor antagonist. Stabilizes mast cells, reducing release of histamine and other mediators of allergic response.

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.
Terminal elimination half-life is approximately 7 hours in adults, which supports twice-daily dosing for sustained ocular effects.
Primarily renal (approximately 40% as metabolites, <1% as unchanged drug) and fecal (approximately 40% as metabolites).
Primarily renal excretion as unchanged drug (approximately 30-40% of dose) and biliary/fecal elimination of metabolites (60-70%).
