Pilot study on manufacture of theophylline microcapsule by isolation method of congelation - phase

ABSTRACT

Preparation of theophylline microcapsule by the coacervation - phase seperation method. Theophylline microcapsule has been prepared by coacervation - phase seperation, using ethyl cellulose as the coating material. Ethyl cellulose sustanined significally the release of theophylline from microcapsule. Microcapsule has been used for preparation of theophylline sustained - release tablet.
