Abstract

Aim: The aim of the present research work was to develop a sensitive, rapid and accurate, stability-indicating
RP-UPLC method for the simultaneous estimation of voxilaprevir (VXR), sofosbuvir (SFR), and velpatasvir
(VLR) in formulations. Materials and Methods: The chromatographic separation of mixture of VXR, SFR, and
VLR was attained in isocratic method utilizing a mobile phase of 0.01N potassium dihydrogen orthophosphate
(pH 4.8) and methanol in the proportion of 50:50% v/v utilizing a CHS C18 column which has dimensions of
100 × 2.1 mm, 2.0 m particle size and the flow rate of 1.0 mL/min. The detection system was monitored at 260 nm
wavelength maximum with 1.0 mL injection volume. Results: The retaining time for VXR, SFR, and VLR was
achieved at 1.468 min, 0.606 min, and 0.848 min, respectively. VXR, SFR, and VLR and their combined drug
formulation were exposed to thermal, acidic, oxidative, photolytic, and alkaline conditions. The present method
was validated as per the guidelines given by the ICH for specificity, accuracy, sensitivity, linearity, and precision.
Conclusion: The developed method was highly sensitive, rapid, precise, and accurate than the earlier reported
methods. The total run time was decreased to 3.0 min; hence, the technique was more precise and economical.
Stability studies directed for the suitability of the technique for degradation studies of VXR, SFR, and VLR. The
projected method can be utilized for routine analysis in quality control department in pharmaceutical trades.
