CLINICAL PHARMACOLOGY
MECHANISM OF ACTIONS
Cetirizine, a human metabolite of hydroxyzine, is an antihistamine;
its principal effects
are mediated via selective inhibition of peripheral H receptors. The
antihistaminic activity
of cetirizine has been clearly documented in a variety of animal and
human models. _In_
_vivo_ and _ex vivo_ animal models have shown negligible
anticholinergic and anti-
serotonergic activity. In clinical studies, however, dry mouth was
more common with
cetirizine than with placebo. _In vitro_ receptor binding studies have
shown no measurable
affinity for other than H receptors. Autoradiographic studies with
radiolabeled cetirizine
in the rat have shown negligible penetration into the brain. _Ex vivo_
experiments in the
