About: A quality by design-based stability indicating HPLC method has been developed for hydroxychloroquine sulfate impurities. The optimized HPLC method can detect and quantify the hydroxychloroquine sulfate and related organic impurities in pharmaceutical solid oral dosage forms. Nowadays, for the quantification of impurities in drug products demands more comprehensive way of analytical method development. The quality by design approach allows the assessment of different analytical parameters and their effects with minimum number of experiments. A highly sensitive and stability indicating RP-HPLC method was developed and evaluated the risk assessment prior to method validation. The chromatographic separation was achieved with X-terra phenyl column (250 × 4.6 mm, 5 µm) using phosphate buffer (0.3 M and pH 2.5). The gradient method flow rate was 1.5 mL min(−1) and UV detection was made at 220 nm. The calibration curve of hydroxychloroquine sulfate and related impurities were linear from LOQ to 150% and correlation coefficient was found more than 0.999. The precision and intermediate precision % RSD values were found less than 2.0. In all forced degradation conditions, the purity angle of HCQ was found less than purity threshold. The optimized method found to be specific, accurate, rugged, and robust for determination of hydroxychloroquine sulfate impurities in the solid oral dosage forms. Finally, the method was applied successfully in quality control lab for stability analysis.   Goto Sponge  NotDistinct  Permalink
