An Anti-Inflammatory and Analgesic Drug Etoricoxib Investigated by Design of Experimentation (DOE) and in Vitro Characterization

Abstract

The objective studies enhance drug release of etoricoxib by Binders, disintegrant& β- Cyclodextrin. The 2 level factorial designs employing (DOE) Design expert software; 3 independent with 3 central points. The prepared granules and tablets were subjected to flow, physical characteristics and dissolution. The optimized formulation exhibited 4 independent variables Y1 (DR 30), Y2 (DR 60), Y3 (DR 90) Y4 (T50 30), Y5 (DE10). DoE used to find response surface plots, optimization and Desirability and analysis of variance (ANOVA), p <0.005 indicates that the ANOVA of responses (dependent variables) Y1, Y2, Y3, Y4& Y5 is significant. The formulation Fa, formulated employing PVP as binder (factor A) and potato starch as disintegrant (factor B) had the highest drug release rate of 95 % in 1 h. The desirability function was 0.90170 and the predicted and experimental values had strong correlations.
