DISOMER vs FEXOFENADINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective dopamine D2 receptor antagonist; also blocks alpha-1 adrenergic, histamine H1, and muscarinic M1 receptors.
Selective peripheral H1-receptor antagonist; inhibits histamine release from mast cells and basophils, reducing allergic symptoms without significant central nervous system penetration.
Adults: 1 mg orally once daily.
60 mg orally twice daily or 180 mg orally once daily; maximum 180 mg/day.

12–15 hours in adults with normal renal function; prolonged to 30–40 hours in severe renal impairment (CrCl <30 mL/min).
14.4 hours in healthy adults; prolonged in renal impairment (up to 58 hours in end-stage renal disease) requiring dose adjustment.
Renal: 80% as unchanged drug; biliary/fecal: 15% as metabolites; <5% unchanged in feces.
Primarily fecal (80%) with approximately 11% renal excretion of unchanged drug. Biliary excretion contributes to fecal elimination.
