A NEW RP-HPLC METHOD FOR ESTIMATION OF VERICIGUAT IN BULK DRUG AND PHARMACEUTICAL DOSAGE FORM
Main Article Content
Abstract
A simple, rapid, specific and accurate reverse phase high performance liquid chromatographic method has been
developed for the validation of Vericiguat in bulk as well as in marketed pharmaceutical dosage form. This separation was
performed on a Symmetry ODS C18 (4.6×250mm, 5μm) column with Methanol:Phosphate Buffer (55:45) v/v as
mobile phase at a flow rate of 1.0 mL min−1 with UV detection at 225 nm; the constant column temperature was
ambient. The run time under these chromatographic conditions was less than 8 min. The retention time of Vericiguat
was found to be 2.252. The calibration plot was linear over the concentration range of 6 - 14 μg mL−1 with limits of
detection and quantification values of 1.2 and 3.6 μg mL−1 respectively. The mean % assay of marketed formulation was
found to be 99.86%, and % recovery was observed in the range of 98-102%. Relative standard deviation for the
precision study was found <2%. The developed method was simple, precise, specific, accurate and rapid, making it
suitable for estimation of Vericiguat in bulk and marketed pharmaceutical dosage form dosage form.
