the chemical name (±)-4-[1
hydroxy-4-[4-(hydroxydiphenylmethyl)-1-piperidinyl]-butyl]-α,α-dimethyl
benzeneacetic acid
hydrochloride. It has the following chemical structure
The molecular weight is 538.13 and the empirical formula is C
H NO •HCl.
Fexofenadine hydrochloride is a white to off-white crystalline powder.
It is freely soluble in methanol
and ethanol, slightly soluble in chloroform and water, and insoluble
in hexane. Fexofenadine
hydrochloride is a racemate and exists as a zwitterion in aqueous
media at physiological pH.
Fexofenadine hydrochloride is formulated as a tablet for oral
administration. Each tablet contains 30,
60, or 180 mg fexofenadine hydrochloride (depending on the dosage
strength) and the following
excipients: croscarmellose sodium, magnesium stearate,
microcrystalline cellulose, and pregelatinized

CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
Fexofenadine hydrochloride, the major active metabolite of
terfenadine, is an antihistamine with
selective peripheral H -receptor antagonist activity. Both enantiomers
of fexofenadine hydrochloride
displayed approximately equipotent antihistaminic effects.
Fexofenadine hydrochloride inhibited
antigen-induced bronchospasm in sensitized guinea pigs and histamine
release from peritoneal mast
cells in rats. The clinical significance of these findings is unknown.
In laboratory animals, no
anticholinergic or alpha -adrenergic blocking effects were observed.
Moreover, no sedative or other
central nervous system effects were observed. Radiolabeled tissue
distribution studies in rats indicated
that fexofenadine does not cross the blood-brain barrier.
