Herein, an electrochemical sensor has been proposed for the determination of losartan (LOS) in pharmaceutical formulations. A room temperature ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate (BMIM.PF6) was applied to fabricate a modified carbon ceramic electrode (IL-CCE). The electrochemical studies were performed by the cyclic and linear sweep voltammetry (CV and LSV), chronoamperometry and electrochemical impedance spectroscopy (EIS) techniques. The anodic peak currents were increased with the LOS concentration and indicated a linear dynamic range from 20 to 200 μM and a detection limit of 11.7 μM (S/N = 3) under the optimized conditions. Satisfactory results were obtained by analysis of LOS in pharmaceutical tablets.
