Liquid chromatography tandem mass spectrometry determination method of bencycloquidium bromide: application to drug interaction study in human - Vol.13(10) - M P Innovare Academic Sciences Pvt Ltd 2021 - 43-46p.
Objective: This study was conducted to develop a sensitive and effective LC-MS/MS method for the determination of bencycloquidium bromide (BCQB) and its application in pharmacokinetic drug interaction study between BCQB and paroxetine. Methods: The chromatographic separation was performed on Hedera ODS-2 C18 column with a mobile phase consisted of acetonitrile-10 mmol/l ammonium acetate containing 0.2% acetic acid (33:67, v/v) at 550μl/min, and the plasma samples were processed using solid-phase extraction. The MS/MS transitions were m/z 330.2→ 142.0 for BCQB and m/z 344.2→ 156.1 for the I. S in positive ESI mode.Results: The validated method was linear over the concentration range of 2-1200 pg/ml with the correlation coefficient r2>0.998. The intra-and inter-batch precisions of the assay were lower than 8.2% and 9.1%, respectively. The lower limit of quantification (LLOQ) was 2 pg/ml. The stability data at different storage conditions of BCQB were within±5% RE. The mean AUC0-36 of BCQB was increased by approximately 33%, after the administration of BCQB alone and upon co-administration with paroxetine during the drug interaction study.Conclusion: The LC-MS/MS method validated in this study was robust, reproducible, accurate, precise and reliable and was successfully applied in the pharmacokinetic drug interaction studies.
