Implementing Analytical Quality by Design (AQbD) Approach for Simultaneous Estimation of Tadalafil and Macitentan by RP-HPLC Method
Abstract
Abstract The principle motive behind this work is to develop robust, low cost, and regulatory flexible method for Tadalafil and Macitentan by RP-HPLC using Analytical Quality by Design principles. Failure Mode and Effects Analysis was performed and the risk priority number was calculated, from this analysis independent variables were selected. Optimization of chromatographic condition was performed using Central Composite Design. The separation was achieved using phenomex gemini C18 (150 mm,...
