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 peripheral H1-receptor antagonist. Competitively inhibits histamine at the H1 receptor, preventing histamine-mediated symptoms such as pruritus, sneezing, and rhinorrhea.
2.5 mg orally every 4 to 6 hours as needed; maximum 10 mg per day.
Oral, 10 mg once daily; may be increased to 10 mg twice daily if needed.

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; increases to approximately 20 hours in renal impairment (CrCl <40 mL/min).
Renal excretion of unchanged drug and metabolites accounts for approximately 60-80% of the administered dose; biliary/fecal elimination comprises the remainder (20-40%).
Approximately 70% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; 10% is excreted in feces. Biliary excretion is minimal.
