Pharmaceutical and Bio-analytical Applications of Ion Mobility Spectrometry for Determination of Clopidogrel (Plavix)

Clopidogrel, with trade name plavix, is used effectively to reduce the incidence of ischaemic strokes, heart attacks and claudication. In this study, an ion mobility spectrometry (IMS) method was proposed for the clopidogrel determination in analytical and bio-analytical fields. Under experimental conditions, the analytical validation parameters of the proposed method were calculated and reported. The calibration graph was linear in the range of 30.0-2000.0 μg ml-1 for clopidogrel with two orders of magnitude and an appropriate fit of R > 0.99. The coefficient of variation (precision, n = 10) was found to be within 7.5-8.6%, and also the analyte concentrations of 3.0 and 10.0 μg ml-1 were obtained for the limits of detection and quantification, respectively. The developed IMS method was successfully applied to determine clopidogrel with an accurate recovery range (90.0-103.7%) in different matrices. The validation studies showed that the applied IMS was a simple, rapid, sensitive and reliable method for the clopidogrel analysis in the pharmaceutical and biological samples.
