title: Cyclic voltammetric study of lorazepam.
abstract: A Cyclic voltammetric study was made of lorazepam. The best defined cyclic voltammograms were found to be those obtained at pH = 7 with a sweep rate of 600 mv/s. A method is proposed for the determination of lorazepam and was applied to such determination in pharmaceutical preparations; relative errors of less than 3% and relative standard deviation less than 2% were obtained.
