titleOfInvention |
Preparation process of sustained release compositions and the compositions thus obtained |
abstract |
The invention relates to a preparation process of particles designed to release an effective amount of active ingredient over a predetermined period of time, said particles comprising one ore more active ingredients in admixture with a bioresorbable and/or biodegradable polymer or copolymer, and the particles thus obtained in a substantially spheroidal form and substantially deprived of active ingredient on the external covering. |
