摘要:
-290 5 A process for reducing solvent contents in drug-containing polymeric compositions may be utilized to reduce the solvent content in implantable medical device wherein the compositions are in reservoirs. Specifically, the solvent contents in the drug-containing polymeric compositions are first reduced by one or more conventional drying methods, to a range from about 0.5 weight percent to about 10 10 weight percent of the total weight of the polymeric composition. Subsequently, the drug-containing polymeric compositions are further treated by a low temperature drying method for further reduction of the solvent content. 1310509,va 17909 speci.290
