Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist at histamine H1 receptors, preventing histamine-mediated symptoms such as itching, sneezing, and vasodilation.
Antihistamine and mast cell stabilizer; inhibits release of histamine and other mediators from mast cells; also blocks histamine H1 receptors.
5 mg orally once daily at bedtime, maximum 10 mg per day.
1 mg orally twice daily; ophthalmic: 1 drop in each eye every 8-12 hours.

Terminal elimination half-life is 12-15 hours. Clinical context: Allows for twice-daily dosing in allergic rhinitis; steady-state reached in 2-3 days.
Terminal half-life 12-24 hours (mean 18 hours); requires twice-daily dosing after initial titration.
Primarily renal (70-80% as unchanged drug and metabolites), with approximately 5-10% biliary/fecal elimination.
Renal (50-70% as conjugates, <2% unchanged), fecal (<10%), with enterohepatic circulation.
