Abstract
Simple spectrophotometric methods for the determination of diclofenac sodium and piroxicam in bulk samples and pharmaceutical preparations, based on the formation of colored species with 3-methyl-2-benzothiazolinone hydra-zone hydrochloride - Ce+ 4, are presented. The methods are simple, sensitive, rapid and accurate. The results obtained are reproducible with a coefficient of variation less than 2%.Keywords
