ANALYTICAL METHOD DEVELOPMENT & VALIDATION FOR RELATED SUBSTANCES IN DIPYRIDAMOLE BY RP-HPLC
AbstractSimple RS method is developed and validated as reversed-phase chromatographic method for the identification and quantification of the dipyridamole related substances-A, B, C, D, E and F. Chromatographic separation has been achieved by using Shodex C18, 150 mm, 4.6 mm diameter, 5 µ column, using mobile phase 0.1 % of formic acid and acetonitrile by eluting in gradient with 1.0 ml flow, detection was achieved at 254 nm by maintaining 25 °C temperature for column. The method is validated as per the ICH guidelines. Linearity was recorded at various concentrations ranges 0.0100 – 6.0051 ppm for related substances A, B, C & 0.0040 – 2.4024 ppm of related substances D, E, F. Recovery RSD value of each related substance was <5.0 % (n=9). RS method for related substances in dipyridamole is found specific, linear, accurate, precise, rugged and robust hence the validated method is suitable to identify the related substances in dipyridamole drug.
