BROMPHENIRAMINE MALEATE vs FEXOFENADINE 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 peripheral H1-receptor antagonist; inhibits histamine release from mast cells and basophils, reducing allergic symptoms without significant central nervous system penetration.
4 mg orally every 4-6 hours, not to exceed 24 mg/day. Alternatively, extended-release: 12 mg every 12 hours.
60 mg orally twice daily or 180 mg orally once daily; maximum 180 mg/day.

Terminal half-life 22-25 hours; prolonged in hepatic impairment or elderly (up to 40 hours).
14.4 hours in healthy adults; prolonged in renal impairment (up to 58 hours in end-stage renal disease) requiring dose adjustment.
Renal (85-90% as metabolites, 5-10% unchanged); biliary/fecal <5%.
Primarily fecal (80%) with approximately 11% renal excretion of unchanged drug. Biliary excretion contributes to fecal elimination.
