Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine; H1-receptor antagonist that competes with histamine for binding at H1 receptor sites, thereby preventing histamine-mediated allergic responses.
Competitive antagonist of histamine H1 receptors; inhibits histamine-mediated vasodilation, increased capillary permeability, and bronchoconstriction in allergic reactions.
100-200 mg orally every 12 hours; maximum 400 mg/day.
2.5 mg orally every 4-6 hours as needed; maximum 10 mg per 24 hours.

Terminal elimination half-life is approximately 4-6 hours in adults with normal renal function; clinically relevant dosing every 4-6 hours is recommended.
Terminal elimination half-life approximately 3–4 hours in healthy adults; prolonged in renal impairment (up to 12 hours).
Primarily renal excretion (80-90% as unchanged drug) via glomerular filtration and tubular secretion. Biliary/fecal excretion accounts for approximately 5-10%.
Renal (primarily as metabolites; ~70% recovered in urine within 24 hours, <5% unchanged). Fecal elimination is minor.
