Zertan contains (Cetirizine hydrochloride) which is an antihistamine (H1 receptor) devoid of any anticholinergic or antiserotonin

effects and it doesn’t induce neither sedation nor behavioral changes at the pharmacological active doses. This may be explained

by the fact that Cetirizine does not cross the blood brain barrier. Cetirizine also inhibits the histamine-mediated “early” phases of

the cutaneous allergic reactions. Also Cetirizine markedly reduces bronchial hyperreactivity to histamine in the asthmatic patients.

It also reduces the allergic reactions induced by specific allergens. Peak blood levels are reached within one hour after oral

administration of Cetirizine. The plasma half life is approximately 10 hours in adults, 6 hours in children aged 6 to 12 years and 5

hours in children aged 2 to 6 years. Cetirizine is strongly bound to plasma proteins and the plasma levels are linear with dose given.

The cumulative urinary excretion represents about two third of the dose given.
