Abstract

Objectives: To develop a formulation for metronidazole (MTZ) microcapsules and investigate the influence of the multilayered coating system intending to release the drug in the colon. Methods: MTZ microcapsules were prepared by coagulation method and then coated by the film coating method. Results: The final microcapsules limited MTZ released during the first five hours at pH 1.2 and 7.4 (simulating the upper gastrointestinal tract) and yielded a high rate of MTZ release at pH 6.8 (simulating the colon environment).
