Abstract:	A new liquid chromatography/atmospheric pressure chemical ionization-tandem mass spectrometry (LC/APCI-MS/MS) method with on-line sample clean-up for the determination of telmisartan in human blood plasma is presented. This technique is compared to a previously introduced enzyme-linked immunosorbent assay (ELISA), where fluorescence is used as detection method. For the LC/MS method applying an internal calibration via a deuterated internal standard, the limit of detection was 0.3 ng/mL, the limit of quantification was 0.9 ng/mL and the linear range extended from 0.9 to 1000 ng/mL. Forty-eight plasma samples from four healthy volunteers were analyzed in a pharmacokinetic study to obtain data for the method comparison. As a result, these two new and independent analytical methods for the determination of telmisartan in human blood plasma proved to yield comparable results for the amount of analyte.
