Summary for Patent: 6,544,559
|Title:||Microencapsulated 3-piperidinyl-substituted 1,2-benzisoxazoles and 1,2-benzisothiazoles|
|Abstract:||Sustained-release microparticle composition. The microparticle composition can be formulated to provide multi-phasic release. In one aspect, the composition includes microparticles having more than one rate of release. In another aspect, the composition includes microparticles that exhibit diffusional release and microparticles that exhibit biodegradation release.|

1. A sustained-release microparticle composition, comprising: a first microparticle comprising a first active agent and a first biodegradable and biocompatible polymeric
matrix, wherein said first active agent is selected from the group consisting of risperidone, 9-hydroxy-risperidone, and pharmaceutically acceptable acid addition salts of the foregoing, and wherein said first microparticle has a first rate of release of
said active agent; and a second microparticle comprising a second active agent and a second biodegradable and biocompatible polymeric matrix, wherein said second microparticle has a second rate of release of said active agent different from said first
rate of release.
2. The sustained-release microparticle composition of claim 1, wherein said second active agent is the same as said first active agent.
3. The sustained-release microparticle composition of claim 1, wherein said second active agent is selected from the group consisting of risperidone, 9-hydroxy-risperidone, and pharmaceutically acceptable acid addition salts of the foregoing.
