This report describes the development and validation of a chromatography/tandem mass spectrometry method for the quantitative determination of pravastatin and its metabolite (3α-hydroxy pravastatin) in plasma and urine of pregnant patients under treatment with pravastatin, as part of a clinical trial. The method includes a one-step sample preparation by liquid-liquid extraction. The extraction recovery of the analytes ranged between 93.8 and 99.5% in plasma. The lower limits of quantitation of the analytes in plasma samples were 0.106ng/mL for pravastatin and 0.105ng/mL for 3α-hydroxy pravastatin, while in urine samples they were 19.7ng/mL for pravastatin and 2.00ng/mL for 3α-hydroxy pravastatin. The relative deviation of this method was
