Abstract

A new method has been established for the simultaneous estimation of Telmisartan and Atorvastatin calcium by RP-HPLC method. The chromatographic conditions were successfully developed for the separation of Telmisartan and Atorvastatin calcium by using boston ODS C18 column, flow rate was 1.0ml/min, mobile Phase consists of methanol:Acetonitrile:buffer in ratio of 35:25:40. Detection wave length was 235nm.The instrument used was SHIMADZU HPLC auto sampler. The retention time of Atorvastatin calcium and Telmisartan was found to be 2.350 and 3.490 minutes respectively. The analytical method was validated according to ICH guidelines (ICH Q2b). The correlation coefficient (r2) was found to be 0.997 and 0.999 for Telmisartan and Atorvastatin calcium respectively. % mean recovery was found to be 100.943% and 100.576% for Telmisartan and Atorvastatin calcium respectively. %RSD for precision on replicate injection was 0.46 and 0.70 for Telmisartan and Atorvastatin calcium respectively. The validation study was found to be precise, robust, and repeatable.


Keywords: Telmisartan, Atorvastatin calcium, ICH guidelines, Validation.
