DEVELOPMENT AND VALIDATION OF UV SPECTROPHOTOMETRIC METHOD FOR SIMULTANEOUS ESTIMATION OF RISPERIDONE AND QUERCETIN IN SLNS FORMULATION

A UV spectroscopic method was developed to measure risperidone (Ris) and quercetin (Que) using methanol as a solvent. The method was validated for precision (intraday and interday), limit of quantification (LOQ), limit of detection (LOD and accuracy, proving to be sensitive, fast, accurate, and economical. This technique can be used to determine the concentrations of Ris and Que in SLNs.
