Abstract
A highly senstive and rapid LC-MS/MS method has been developed and validated for the estimation of desvenlafaxine in rabbit plasma. The chromatographic separation was performed with 0.2% formic acid: methanol at flow rate of 0.4 mL/min on Symmetry Shield RP18 column with a total run time of 3.0 min. TheMS/MS ion transitions monitored were 263.90? 58.10 for desvenlafaxine and 281.30--> 86.10 for IS (metaprolol). Method validation and pre-clinical sample analysis were performed as per FDA guide lines and the results met the acceptance crieteria. The lower limit of quantification achieved was 0.5 ng/mL and the linearity was observed from 0.5 to 1500 ng/mL. This novel method has been applied to pharmacokinetic study of desvenlafaxine in rabbits.
