Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antagonist at histamine H1 receptors; also exhibits anticholinergic, antiemetic, and sedative effects.
Competitive antagonist of histamine H1 receptors; inhibits histamine-mediated vasodilation, increased capillary permeability, and bronchoconstriction in allergic reactions.
12.5-25 mg intramuscularly or intravenously every 4-6 hours as needed; maximum 100 mg/day.
2.5 mg orally every 4-6 hours as needed; maximum 10 mg per 24 hours.

Terminal elimination half-life is 10-14 hours in adults; may be prolonged in elderly or hepatic impairment.
Terminal elimination half-life approximately 3–4 hours in healthy adults; prolonged in renal impairment (up to 12 hours).
Primarily renal (approximately 70%) as metabolites and unchanged drug; biliary/fecal excretion accounts for ~20%.
Renal (primarily as metabolites; ~70% recovered in urine within 24 hours, <5% unchanged). Fecal elimination is minor.
