Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine; binds to histamine H1 receptors, blocking the effects of histamine; also exhibits anticholinergic and mild sedative properties.
Loratadine is a long-acting second-generation antihistamine that selectively antagonizes peripheral histamine H1 receptors, thereby inhibiting the effects of histamine released from mast cells and basophils, reducing allergic symptoms.

6.9 ± 1.7 hours in adults; prolonged to 12-18 hours in elderly or patients with hepatic impairment, requiring dosing interval adjustment.
The terminal elimination half-life of loratadine is 8-14 hours (mean 11 hours) in healthy adults; for the active metabolite descarboethoxyloratadine, half-life is 17-24 hours (mean 20 hours). This supports once-daily dosing.
Primarily renal (approximately 85% as unchanged drug and metabolites) and fecal (15%) via biliary elimination.
Loratadine is primarily eliminated via hepatic metabolism, with approximately 80% of the dose excreted as metabolites in urine (40%) and feces (40%). Less than 1% is excreted unchanged in urine.
