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.
Fexofenadine is a selective peripheral H1-receptor antagonist that inhibits histamine release from mast cells and basophils.
Adults: 1 mg orally once daily.

12–15 hours in adults with normal renal function; prolonged to 30–40 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 14.4 hours in healthy adults. In renal impairment, half-life may be prolonged up to 59 hours.
Renal: 80% as unchanged drug; biliary/fecal: 15% as metabolites; <5% unchanged in feces.
Primarily excreted unchanged in feces (80%) and urine (11%). Biliary excretion contributes to fecal elimination.
