| titleOfInvention | Production of ethyl cellulose microcapsule preparation to contrive sustained release of oral antibiotic |
| abstract | PURPOSE: To obtain the titled preparation having excellent sustained release and acting for a long time, by dispersing a solution containing ethyl cellulose and an antibiotic of core substance in an organic solvent into a dispersion medium containing a dispersing and separating agent and then evaporating the organic solvent. n CONSTITUTION: Ethyl cellulose is dissolved in an organic solvent comprising a lower alcohol and/or lower alkyl ketone, mixed with an oral antibiotic (e.g. cefalexin) as a core substance, well stirred and dispersed to prepared a primary emulsion. Then the primary emulsion is uniformly dispersed into a dispersion medium premixed with a dispersing and separating agent such as a surface active agent (e.g. sorbitan tristearate) having 2W3 HBL value and the organic solvent is evaporated to give microcapsules of matrix type. n COPYRIGHT: (C)1988,JPO&Japio |
