Abstract
The stability of innovative drug formulations and the development of appropriate stability-indicating methods remain major focuses of recent pharmaceutical analysis. In the present study, an efficient stability-indicating HPLC-DAD technique has been described and validated for the determination of Vericiguat (VER); a novel oral soluble guanylate cyclase (sGC) stimulator used in heart failure. VER's stability under various stress conditions was examined. It was shown that VER was sensitive to alkaline, oxidative and thermal degradation. Mass spectrometry (MS) in electrospray ionization mode was performed to figure out the structure of the alkaline and oxidative degradation products. Efficient separation of VER and its induced degradation products was accomplished using isocratic elution mode on the Inertsil ODS-C18 column. The mobile phase composed of water: acetonitrile (70:30 v/v) with 0.1% O-phosphoric acid; pH was adjusted to 2.22 and a flow rate of 0.80 mL/min. VER was detected at 332 nm over a concentration range of 2.00-20.00 μg/mL. The retention time was 4.500 ± 0.005 min and the correlation coefficient was 0.9996. Following the International Conference of Harmonization's guidelines, the analysis was validated to be specific, fast, simple, precise and accurate for utilization in routine analysis and quality control of VER in its pharmaceutical formulation. Additionally, the suggested t
