A sustained-release tablet is disclosed. The tablet is a combination of powder (A) comprising an oil component, water insoluble polymer, or both, and a pharmaceutically active component and powder (B) comprising a water soluble polymer and a pharmaceutically active component. An ideal release rate for individual pharmaceutically active component can easily be ensured by controlling its release rate by changing the ratio of powders (A) and (B).
