ABSTRACT

A simple, accurate, rapid and precise reverse phase high performance liquid chromatographic method was developed for simultaneous estimation of Irbesartan and Atorvastatinin synthetic mixture. Inertsil C18, 150 mm x 4.6 mm, 5 ?m particle size in gradient mode with mobile phase Acetonitrile: 0.1% Formic acid (40: 60 v/v) and pH adjusted to 3.5 ± 0.1 with orthophosphoric acid was used. The flow rate was 1.0 ml/min and absorbance of individual component was measured at 262 nm. The retention times of Irbesartan and Atorvastatin were found to be 3.993 and 7.733 min, respectively. Linearity for Irbesartan and Atorvastatin was in the range of 400 - 800 and 50- 100?g/ml with correlation coefficient values 0.9995and 0.9994, the percentage recovery obtained was 99.88and 99.70 %, respectively.

Key Words: Irbesartan, Atorvastatin, RP-HPLC, Method validation.
