Development of Optimal Extended-Release Formulations for Poorly Water-Soluble Drug (Mefenamic Acid) Using Quality by Design Principles
Main Article Content
Abstract
The aim of this project was to develop optimal extended-release tablets of mefenamic acid using the principles of Quality by Design (QbD). Mefenamic acid is a poorly water-soluble drug, classified as a BCS Class II drug (low solubility, high permeability). The formulations were designed using the Design of Experiment (DoE) feature of JMP software. Lactose, in the range of 15–25%, was used as a filler, while HPMC K100M, in the range of 10–15%, was used as a modified-release agent to design 12 different formulations. Various physical parameters of the tablets, namely thickness, diameter, hardness, friability, and in vitro release, were evaluated. The physical parameters of the compressed tablets were found to be satisfactory for all formulations. In vitro drug release studies were performed in 900 mL of phosphate buffer medium at pH 7.1 containing 2% cetyltrimethyl ammonium bromide (CTAB) using a dissolution apparatus (paddle method). The in vitro release profiles indicated that all formulations of mefenamic acid functioned effectively as extended-release tablets. The drug release percentage of all formulations met the Quality Target Product Profile (QTPP) goal of achieving 50–85% drug release within six hours.
