Abstract: A space filled drug release structure and a method of manufacturing the same are disclosed. The structure is composed of a highly water-absorbing polymeric matrix and drug particles dispersed in the matrix. The matrix has pores and passages interconnecting the pores together. Because some water is present in the matrix, gastric acid can easily penetrate into the matrix to reach each drug particle. The surface of each drug particle is therefore possible to contact with the gastric acid. The drug releasing rate is therefore fast. Such structure is helpful for those drugs with low dissolution ability in the gastric acid.
