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.
Fexofenadine hydrochloride is a selective peripheral H1-receptor antagonist. It blocks the action of histamine at the H1 receptor, preventing histamine-mediated symptoms such as itching, sneezing, rhinorrhea, and urticaria.

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 14.4 hours (range 11–17 hours) in healthy adults. Clinically, this supports twice-daily dosing for symptomatic relief.
Primarily renal (approximately 40% as metabolites, <1% as unchanged drug) and fecal (approximately 40% as metabolites).
Approximately 95% of the dose is excreted unchanged in feces (80%) and urine (15%). Fexofenadine undergoes minimal hepatic metabolism (<5%).
