Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective peripheral H1-receptor antagonist. Competitively inhibits histamine at the H1 receptor, preventing histamine-mediated symptoms such as pruritus, sneezing, and rhinorrhea.
Antagonist at histamine H1 receptors; also exhibits anticholinergic, antiemetic, and sedative effects.
Oral, 10 mg once daily; may be increased to 10 mg twice daily if needed.
12.5-25 mg intramuscularly or intravenously every 4-6 hours as needed; maximum 100 mg/day.

Terminal elimination half-life is approximately 8-11 hours in healthy adults; increases to approximately 20 hours in renal impairment (CrCl <40 mL/min).
Terminal elimination half-life is 10-14 hours in adults; may be prolonged in elderly or hepatic impairment.
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.
Primarily renal (approximately 70%) as metabolites and unchanged drug; biliary/fecal excretion accounts for ~20%.
