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 mouse have shown
that systemically administered cetirizine does not significantly
occupy cerebral H receptors.
