Electrochemical Determination of Ipragliflozin in Pure Form and in Spiked Human Plasma on a Glassy Carbon Electrode

Abstract

Ipragliflozin, a highly potent and selective sodium glucose cotransporter II inhibitor, is an effective blood glucose lowering drug in patients with type 2 diabetes mellitus by promoting urinary glucose excretion. The present work represents the first electrochemical determination of ipragliflozin that depends on the oxidation of sulfur atom present in its structure. Cyclic wave and differential pulse voltammetry were applied by scanning potential over range of 0 to 2.8 V vs the reference electrode Ag/Ag+ in non-aqueous medium. The method was developed and validated in accordance with the guidelines of the International Council for Harmonisation (ICH). With a detection limit of 1.98 × 10–6 M, the method was considered to be linear in the range of 7.5 × 10–6–1 × 10–3 M. The method was then efficiently applied for the determination of ipragliflozin in spiked human plasma. The method proved to be an excellent green analysis according to analytical eco-scale for greenness assessment.
