摘要:
A process for reducing solvent contents in drug-containing polymeric compositions, contained in reservoirs in a medical device, involves first reducing the solvent content by one or more conventional drying methods to a range from about 0.5 weight percent to about 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.
