Evaluation of a capillary electrophoresis method for routine determination of varenicline tartrate in quality control laboratories

Abstract: In this study, analyses were carried out on a fused-silica capillary (i.d. 50.0 µm, total length 48.5 cm, and effective length 40.0 cm) in normal mode by applying a voltage of 20 kV. Sample injections were made in hydrodynamic mode over 7 s under a pressure of 50 mbar. The capillary temperature was set at 35 ºC and the detection was performed at a wavelength of 205 nm. The background electrolyte was 40 mM citrate buffer at pH 6.0 and the internal standard was labetalol hydrochloride. The total analysis time wa… Show more

“…The usual oral dosage in adults is 1 mg twice daily for 12 weeks. Different methods have been designated for the quantitation of VRN in its bulk and tablets using spectrofluorimetry [4,5], spectrophotometry [6], HPLC [4,[7][8][9][10][11], capillary electrophoresis [12] and LC/MS/MS [13] in addition to pharmacokinetic studies [13,14]. Additionally, electrochemical methods have been reported [14].…”

“…Most of them are dedicated to the chromatographic methods such as HPLC, UHPLC with conventional UV or advanced MS detection . To our best knowledge, only four papers describe CE methods for the separation of VAR and only one of them is associated with the analysis of VAR in complex biological matrices such as human urine . Although the published method provides favorable performance parameters for the trace analysis of VAR in human urine, there are still some issues that can be solved when shortening and/or simplifying of the analysis is demanded.…”
