Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
H1-receptor antagonist; competes with histamine for H1-receptor sites on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract, blocking histamine-induced bronchoconstriction, vasodilation, and increased capillary permeability.
Selective histamine H1-receptor antagonist; inhibits histamine-mediated allergic and inflammatory responses.
2.5 mg orally every 4 to 6 hours as needed; maximum 10 mg per day.
5-10 mg orally once daily; maximum 10 mg per day.

Terminal elimination half-life is approximately 20-25 hours in healthy adults; may be prolonged in elderly or patients with hepatic impairment.
Terminal elimination half-life is approximately 8-11 hours in healthy adults; prolonged in renal impairment (up to 20-30 hours in moderate to severe impairment).
Renal excretion of unchanged drug and metabolites accounts for approximately 60-80% of the administered dose; biliary/fecal elimination comprises the remainder (20-40%).
Primarily renal (approximately 70% as unchanged drug via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%).
