摘要: Methods for preparing microparticles having reduced residual solvent levels. Microparticles are contacted with a non-aqueous washing system to reduce the level of residual solvent in the microparticles. Preferred non-aqueous washing systems include 100% ethanol and a blend of ethanol and heptane. A solvent blend of a hardening solvent and a washing solvent can be used to harden and wash microparticles in a single step, thereby eliminating the need for a post-hardening wash step.

摘要: Methods of forming compositions for the sustained release of water soluble active agents, including biologically active polypeptides and products produced by the process are described. Improved product characteristics and ease of scale-up can be achieved using a novel coacervation process wherein at least one coacervation agent is added to the mixture comprising the active agent and the polymer in at least two distinct stages.
