| The present investigation is aimed to develop self-microemulsifying drug delivery system (SMEDDS) to improve the in vitro dissolution of a BCS (Biopharmaceutical Classification System) class II anti emetic agent, domperidone. Solubility study was performed to identify the ingredients showing highest solubility of domperidone. The ternary phase diagrams were plotted for selected components to identify the area of microemulsion existence. D-optimal mixture experimental design was applied to optimize a liquid SMEDDS using formulation variables; the oil phase X1 (Oleic acid), the surfactant X2 (Labrasol) and the co-surfactant X3 (Transcutol HP). The liquid SMEDDS were evaluated for droplet size, emulsification time, % transmittance and drug release. Stability... |
