Résumé
OBJECTIVE: To prepare and evaluate esomeprazole magnesium enteric-coated capsules which is compacted by multiple-unit pellet system (MUPS). METHODS: The esomeprazole magnesium enteric-coated pellets were prepared by fluid bed coating technology, and the effects of isolation layer, amont of core, and thickness of enteric-coated film on the quality of the product were e-valuated. RESULTS: The prepared esomeprazole magnesium enteric-coated capsules showed good release behavior in artificial gastric fluid. The dissolution in artificial intestinal fluid was rapid and complete. CONCLUSION: The established process of preparing esomeprazole magnesium enteric-coated pellets is feasible and reproducible, and the product has similar quality with the original preparation. It is expected to be used in the industrial production.
