Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine H1 receptors; inhibits histamine-mediated vasodilation, increased capillary permeability, and bronchoconstriction in allergic reactions.
Selective histamine H1 receptor antagonist. Stabilizes mast cells, reducing release of histamine and other mediators of allergic response.
2.5 mg orally every 4-6 hours as needed; maximum 10 mg per 24 hours.
1 drop in each affected eye twice daily, approximately 6-8 hours apart.

Terminal elimination half-life approximately 3–4 hours in healthy adults; prolonged in renal impairment (up to 12 hours).
Terminal elimination half-life is approximately 7 hours in adults, which supports twice-daily dosing for sustained ocular effects.
Renal (primarily as metabolites; ~70% recovered in urine within 24 hours, <5% unchanged). Fecal elimination is minor.
Primarily renal excretion as unchanged drug (approximately 30-40% of dose) and biliary/fecal elimination of metabolites (60-70%).
