Abstract
The aim of this study is to develop and validate an accurate, sensitive, rapid, precise, and simple bioanalytical method for the estimation of Azelnidipine (calcium channel blocker, used in hypertension) in the human plasma by using LC-ESI-MS/MS. The method was developed by gradient conditions using 0.1% Formic Acid in Acetonitrile and Milli-Q water with 10mM Ammonium acetate as a mobile phase with a flow rate of 0.5 mL/min. The Analyte and IS (Metoprolol) were separated by using a C18 Phenomenex Kinetex (50x3mm, 5µ) column. 7.0 minutes was the chromatographic run time. The analyte and IS extracted from plasma by simple protein precipitation technique (PPT). The LOD and LLOQ were found to be 0.53125ng/mL and 1.0625ng/mL, respectively. The extraction recovery of the drug from plasma was high. The other validation parameters were found within the range, as mentioned by USFDA and EMA guidelines.
