Abstract

We studied the application of Taguchi orthogonal array (TOA) design during the development of an isocratic stability indicating HPLC method for glimepiride as per TOA design; twenty-seven experiments were conducted by varying six chromatographic factors. Percentage of organic phase was the most significant (p

Abstract

This paper describes the optimization of an isocratic stability indicating HPLC method for Ezetimibe (EZM). A five factor, three-level Box-Behnken experimental design optimized the method. The responses were (1) retention time, (2) tailing factor, and (3) theoretical plates. The quadratic effect of percentage (v/v) acetonitrile was the most significant (p
