preparation Embodiment 1

[0756] (Formulation Example 1) Powdered Drug

[0757] The compound of the present invention or its salt (5 g), lactose (895 g) and cornstarch (100 g) were mixed in a blender to obtain a powdered drug.

preparation Embodiment 2

[0758] (Formulation Example 2) Granules

[0759] A compound of the present invention or a salt thereof (5 g), lactose (865 g) and low-substituted hydroxypropylcellulose (100 g) were mixed, and then a 10% aqueous solution of hydroxypropylcellulose (300 g) was added thereto. The mixture was kneaded, granulated by an extrusion granulator, and dried to obtain granules.

preparation Embodiment 3

[0760] (Formulation Example 3) tablet

[0761] The compound of the present invention or its salt (5 g), lactose (90 g), cornstarch (34 g), crystalline cellulose (20 g) and magnesium stearate (1 g) were mixed in a blender and compressed into tablets by a tablet machine And get the tablet.

[0762] The pharmacological activity of the compound of the present invention or a pharmacologically acceptable salt thereof was examined by the following test.

[0763] (Test Example) Measurement of IL-10 Growth Rate

[0764] The test substance was suspended in 0.5% (w / v) methylcellulose and orally administered to mice at a dose of 100 mg / kg. One hour later, lipopolysaccharide (LPS, Sigma-Aldrich, L2630 (trade name)) (0.4 mg / kg) was intraperitoneally administered to induce inflammation. One hour after LPS administration, blood was collected from the vena cava under isoflurane anesthesia, placed in a test tube containing a serum separator, allowed to stand at room temperature for 20-30 min...
