Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fexofenadine is a selective peripheral H1-receptor antagonist that blocks histamine-mediated effects, reducing pruritus and urticaria.
Fexofenadine is a selective peripheral H1-receptor antagonist that inhibits histamine release from mast cells and basophils.

Terminal half-life: 14.4 hours; clinical context: supports twice-daily dosing in chronic urticaria
Terminal elimination half-life is 14.4 hours in healthy adults. In renal impairment, half-life may be prolonged up to 59 hours.
Fecal (80% as unchanged drug); renal (15%, mostly as metabolites; <5% unchanged)
Primarily excreted unchanged in feces (80%) and urine (11%). Biliary excretion contributes to fecal elimination.
