Two simple, rapid and sensitive extractive spectrophotometric methods have been developed for the assay of ceterizine hydrochloride (CTZH) in bulk drug and in pharmaceutical preparations. These methods are based on the formation of chloroform soluble complexes between CTZH with bromocresol purple (BCP) or bromophenol blue (BPB) in Walpole buffer of pH 2.64 with an absorption maximum at 409 nm and at 414 nm for BCP and BPB, respectively. Reaction conditions were optimised to obtain the maximum… CONTINUE READING
