Differential pulse polarographic investigation of the antifungal drugs itraconazole, ketoconazole, fluconazole and voriconazole using a dropping mercury electrode.

The electrochemical reactions of the antifungal drugs itraconazole, ketoconazole, fluconazole and voriconazole have been investigated by differential pulse polarography (DPP) using a dropping mercury electrode (DME). All investigations were carried out in Britton-Robinson buffer solutions and methanol with varying pH values. Ketoconazole and itraconazole both showed a reduction peak with a potential between -1.5V and -1.6 V. Stable and reproducible conditions for the determination of itraconazole (c = 1 x 10(-7) M) were found within the pH range of 6.0 to 8.0 and for the determination of ketoconazole (c = 5 x 10(-8) M) within pH 6.0 to 7.0. Voriconazole showed a reduction peak with a peak potential of -1.7 V (c = 1 x 10(-5) M) within the pH range of 8.0 to 10.0. In the case of fluconazole no electrochemical activity was found.
