A preparation which can improve solubility of a NPYY5 receptor antagonist in water, even when the NPYY5 receptor antagonist is contained in the preparation at a high content is provided. A solid preparation containing a NPYY5 receptor antagonist, an amorphous stabilizer, and optionally an amorphousization inducing agent. Particularly, when the amorphous stabilizer is hydroxypropylmethylcellulose phthalate and/or hydroxypropylmethylcellulose acetate succinate, and the amorphousization inducing agent is urea and/or saccharine sodium at an addition amount of less than 8% by weight, dissolution out property of a water-hardly soluble NPYY5 receptor antagonist could be improved.
