PRODUCT INTRODUCTION
description
Cetirizine is a member of the class of piperazines that is piperazine in which the hydrogens attached to nitrogen are replaced by a (4-chlorophenyl)(phenyl)methyl and a 2-(carboxymethoxy)ethyl group respectively. It has a role as an anti-allergic agent, a H1-receptor antagonist, an environmental contaminant and a xenobiotic. It is a monocarboxylic acid, a member of piperazines, a member of monochlorobenzenes and an ether.
