title: Determination of miglitol in human plasma by liquid chromatography/tandem mass spectrometry.
abstract: A rapid and sensitive method for the determination of miglitol in human plasma using voglibose as internal standard has been developed and validated. Samples of plasma were deproteinated with acetonitrile and washed with dichloromethane before being analyzed by reversed-phase high-performance liquid chromatography (HPLC). Separation was carried out on a short Nucleosil C(18) column (5 microm, 50 x 4.6 mm i.d.) using 10 mmol/L ammonium acetate at 1.0 mL/min as mobile phase. The detector was an Applied Biosystems Sciex API 4000 mass spectrometer using atmospheric pressure chemical ionization (APCI) for ion production. The instrument was operated at unit resolution in the multiple reaction monitoring mode. The assay was linear over the range 5.00-2000 ng/mL with a limit of detection of 1.00 ng/mL. Intra- and inter-day precision were <2.82% and <2.92%, respectively, with accuracy of 93.3-106%. The assay was successfully applied to a clinical pharmacokinetic study of miglitol given as a single oral dose (50 mg) to healthy volunteers.
