<P>PROBLEM TO BE SOLVED: To provide a method for reducing the content of solvent in drug-containing polymer composition. <P>SOLUTION: In detail, this method, at first, reduces the content of the solvent in the drug-containing polymer composition to a range of 0.5 wt.% to 10 wt.% of the whole weight of the polymer composition by one or more types of conventional drying methods. Sequentially, the drug-containing polymer composition is treated by one or more types of low-temperature (namely, having a processing temperature lower than 60°C) drying method for reducing the content of the solvent till it becomes less than 10,000 ppm. <P>COPYRIGHT: (C)2007,JPO&INPIT |
