Voltammetric determination of droperidol and benperidol

In this study two butyrophenones, droperidol and benperidol were voltammetrically investigated using platinum and specially activated glass carbon electrodes. The behaviours of the substance were investigated in various electrolyte solutions having different pH values and by different scan rates. As a result of the studies it was shown that the quantitative determinations of the substances from their pharmaceutical preparations could be made rapidly and simply without any separation from the excipients.
