BROMPHENIRAMINE MALEATE vs CETIRIZINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine at H1 receptor sites, suppressing histamine-induced vasodilation, increased capillary permeability, and bronchoconstriction.
Selective histamine H1-receptor antagonist; inhibits histamine-mediated allergic and inflammatory responses.
4 mg orally every 4-6 hours, not to exceed 24 mg/day. Alternatively, extended-release: 12 mg every 12 hours.
5-10 mg orally once daily; maximum 10 mg per day.

Terminal half-life 22-25 hours; prolonged in hepatic impairment or elderly (up to 40 hours).
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 (85-90% as metabolites, 5-10% unchanged); biliary/fecal <5%.
Primarily renal (approximately 70% as unchanged drug via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%).
