摘要: Coated microparticles for sustained-release of an active pharmaceutical ingredient after parenteral administration, and methods producing such coated microparticles, are provided. The comprise core particles a first polymeric coating on the particles. is permeable to forms saturated solution within microparticle, resulting in pseudo-zero-sustained release period. A second can be employed add mechanical support or as rate-controlling element.
