## Abstract A rapid and sensitive LC/MS/MS assay was developed and validated for the determination of clopidogrel in human plasma. Clopidogrel was extracted by single liquid–liquid extraction with pentane, and chromatographic separations were achieved on a C~18~ column. The method was validated to
A liquid chromatographic atmospheric pressure chemical ionization tandem mass spectrometric method is described for the determination of 21-hydroxydeflazacort in human plasma using dexamethasone 21-acetate as an internal standard. The procedure requires a single diethyl ether extraction. After evapo
