Abstract Objective Highly responsive simple Liquid-liquid Extraction Glipizide development using deuterated Glipizide and Sitagliptin LC-MS/MS Glipizide for gradation of Glipizide and Sitagliptin in rat plasma Glipizide: The chromatographic condition involves, isocratic mode using waters X-Bridge Cis 3.5µ (150x4.6mm) column. Mobile phase 0.1% orthophosphoric acid and Acetonitrile in the ratio (80:20) was used and detection was carried out in a positive mode of electrospray ionization by using MS. Results Glipizide has been validated, the linearity was observed in the range 10–150 ng/ml and 0.1–1.5 ng/ml for Glipizide and Sitagliptin respectively. For intraday and inter-day precision %RSD values were found to be within the acceptable limits. Recovery studies for Glipizide and Sitagliptin obtained was 99.5% and 98.6% respectively. The battery of stability studies like bench-top, Autosampler stability, freeze-thaw, and long term stability was performed. Conclusion Highly responsive simple liquid chromatography tandem mass spectroscopy assay Glipizidewas developed and witnessed for the gradation of Glipizideand Sitagliptin in rat plasma, the developed Glipizidewas applied to pharmacokinetic studies.
