Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective histamine H1 receptor antagonist; inhibits histamine-mediated allergic and inflammatory responses.
Competitive antagonist of histamine H1 receptors; inhibits histamine-mediated vasodilation, increased capillary permeability, and bronchoconstriction in allergic reactions.
1 capsule (200 mg) orally every 12 hours.
2.5 mg orally every 4-6 hours as needed; maximum 10 mg per 24 hours.

Terminal half-life: 8-12 hours (average 10 hours); prolonged in hepatic impairment (up to 24 h) and severe renal impairment (up to 18 h).
Terminal elimination half-life approximately 3–4 hours in healthy adults; prolonged in renal impairment (up to 12 hours).
Renal: 30-50% unchanged; hepatic metabolism: 50-70% (CYP3A4); biliary/fecal: 10-20%.
Renal (primarily as metabolites; ~70% recovered in urine within 24 hours, <5% unchanged). Fecal elimination is minor.
