This paper deals with an analytical method based on two dimensional capillary electrophoresis (CITP-CZE coupling) with simple UV-detection for the determination of a highly effective drug - varenicline. The method was elaborated with the possibility of its future connection with an advanced detection ending - mass spectrometry. The electrolytes for the CITP (LE = 10 mM NH4Ac + 5 mM HAc + 0,05% m-HEC; TE = 10 mM HAc) and CZE (BGE = 20 mM HAc) separation of varenicline were selected considering such requirements. The UV detector was set at the constant wavelength of 237 nm. The presented CITP-CZE-UV combination enabled rapid and effective evaluation of varenicline in the dosage forms with LOD 5.92 ng/ml.
