Abstract
An isocratic reversed-phase high-performance liquid chromatographic (RP-HPLC) method for determination and evaluation of purity of mosapride citrate in bulk drugs and pharmaceuticals has been developed using Waters Symmetry C 18 column with acetonitrile:0.024 M orthophosphoric acid (28:72, v/v) adjusted to pH 3.0 with triethylamine and photodiode array detector set at 276 nm. The method is simple, rapid, selective and capable of detecting all process related impurities at trace levels in the finished products with detection limits ranging in between 0.2 × 10 −8g and 6.4 × 10 −8g. The method has been validated with respect to accuracy, precision, linearity, ruggedness, and limit of detection and quantification. The linearity range was 125–1000 μg/ml. The percentage recoveries from pharmaceutical dosages were ranged from 95.53 to 100.7. The method was found to be suitable not only for monitoring the reactions during the process development but also quality assurance of mosapride citrate.
