To the best of our knowledge, there is no work in the
literature reported about the spectrophotometric method
for the analysis of FZ using hydrotropic agent. In the
preliminary solubility studies there were more than 32
fold enhancements in the solubility of FZ in mixed
hydrotropic solution. Therefore, it was thought
worthwhile to employ this hydrotropic solution to extract
out the drug from fine powder of tablets to carry out
spectrophotometric estimation. This prompted us to
disclose our results, consisting of new and accurate
method for the determination of drug in pharmaceutical
formulations.
