“…Drug testing and analysis is important in the quality and quantity control of pharmaceutical utilities, and therefore, fast, simple and effective analytical methods are required for the analysis of drug molecules [6]. There are many methods previously used for CTZ determination such as electrophoresis [7], high performance liquid chromatography [8], spectrophotometry [9], HPLC/MS [10], spectrofluorimetry [11], and electrochemical methods [12,13]. All these methods, except electrochemical methods, have some drawbacks like time consuming, requirements for more organic solvents and reagents, and experts for handling, and also inclusion of complicated and expensive procedures [14].…”
