Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective peripheral H1-receptor antagonist. Competitively inhibits histamine at the H1 receptor, preventing histamine-mediated symptoms such as pruritus, sneezing, and rhinorrhea.
Antihistamine and mast cell stabilizer; inhibits release of histamine and other mediators from mast cells; also blocks histamine H1 receptors.
Oral, 10 mg once daily; may be increased to 10 mg twice daily if needed.
1 mg orally twice daily; ophthalmic: 1 drop in each eye every 8-12 hours.

Terminal elimination half-life is approximately 8-11 hours in healthy adults; increases to approximately 20 hours in renal impairment (CrCl <40 mL/min).
Terminal half-life 12-24 hours (mean 18 hours); requires twice-daily dosing after initial titration.
Approximately 70% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; 10% is excreted in feces. Biliary excretion is minimal.
Renal (50-70% as conjugates, <2% unchanged), fecal (<10%), with enterohepatic circulation.
