PROBLEM TO BE SOLVED: To provide a method for producing a solid preparation which is excellent in elution of a water-insoluble physiologically active ingredient and has appropriate hardness without taking complicated steps. SOLUTION: A physiologically active component (A) hardly soluble in water is mixed with a nonionic surfactant and / or an anionic surfactant (B), and then mixed with a water-swellable polymer compound (C). And a method for producing a solid preparation, which comprises granulating. |
