Fexofenadine is rapidly absorbed after oral doses with peak plasma concentrations being reached in 2-3 hours. It is about 60 to 70% bound to plasma proteins. About 5% of the total dose is metabolized, mostly by the intestinal mucosa and by the cytochrome P450 system. Elimination half life is 14 hours. Excretion is mainly in the faces with only 10% being present in the urine. Fexofenadine does not appear to cross the blood-brain barrier.
