Abstract
Compressed-molded preparations are disclosed. In the preparation coated granules of a pharmaceutical composition are compressed and molded together with non-coated component(s) containing 10% or more by weight of non-swelling polymers. According to the preparation there is little breakdown of the coating of coated granules at the time of compressing and molding, and the rate of disintegration, and in turn, the release rate of the pharmaceutical component, can be freely controlled or modulated.
