The voltammetric methods were used for investigatin g the electrochemical properties and the quantitati ve analysis of nitazoxanide at the Hanging mercury dropping ele ctrode (HMDE). The experimental conditions were opt imised to obtain the best characterized peak in terms of p eak height with analytical validation of the method s for each nitazoxanide.. All nitazoxanide were found to adsor b and undergo irreversible reduction reaction at th e working Hanging mercury dropping electrode.
