Disclosed is a preparation which is capable of improving the water solubility of an NPY Y5 receptor antagonist even when the NPY Y5 receptor antagonist is contained in the preparation in a large amount. Specifically disclosed is a solid preparation which contains an NPY Y5 receptor antagonist, carboxymethyl ethyl cellulose, and if necessary, an amorphization inducer. The solid preparation has improved dissolvability of the NPY Y5 receptor antagonist. |
