Abstract:
A rapid and highly sensitive method for the determination of acamprosate (ACM), in human plasma using ESI-LC-MS/MS (electrospray ionization liquid chromatography tandem mass spectrometry) in negative ionization polarity in multiple reactions monitoring (MRM) mode was developed and validated. The procedure involves a simple protein precipitation step. Chromatographic separation was carried out on a Hypersil BDS C(18) column (150 mm × 4.6 mm, 5 µm) with an isocratic mobile phase and a total run time of 2.5 min. The standard calibration curves were linear within the range of 7.04-702.20 ng/mL for ACM (r ≥ 0.990). This study briefly describes the role of ion source design on matrix effects. ACM shows matrix effects in z-spray ionization source design, whereas it has no matrix effects in orthogonal spray ion source design. This method was successfully applied to a pharmacokinetic study after oral administration of acamprosate 333 mg tablet in Indian healthy male volunteers.
