  A fast, simple and particular method for estimation of Doxycycline in healthy human plasma was validated using Minocycline as IS. The analyte and IS were extracted from plasma using SPE. The compound was estranged on a RP column with an isocratic mobile phase consisting of 0.1% formic acid in water and acetonitrile (12:88, v/v), and detected by tandem mass spectrometry in positive ion mode. The ion transition recorded in several reaction monitoring mode were m/z 294.1→225.1 for Doxycycline and m/z 286.1→217.1 for IS. Linearity in plasma was observed over the concentration range 0.3-30 ng/mL for Doxycycline. The mean recovery for Doxycycline was 83.7%, with a lower limit of quantification of 0.3 ng/mL. The coefficient of variation of the assay was less than 6.8%, and accuracy of 96.1% to 102.2%. The validated method was applied to bioequivalence study of 150 mg Doxycycline Hy.. View More»
