The tablet of the present invention comprising an uncoated tablet containing 7-[4-(4-benzo[b]thiophen-4 -yl-piperazin-1-yl)butoxy]-1H-quinolin-2-one or a salt thereof as an active ingredient, excipients such as lactose, corn starch, and microcrystalline cellulose; disintegrants such as low-substituted hydroxypropylcellulose, croscarmellose sodium, and sodium carboxymethyl starch; binders such as hydroxypropylcellulose; lubricants such as stearate; and further comprising a coating layer, containing hypromellose; talc; titanium oxide; colorant; and the like, the coating layer being applied to the surface of the uncoated tablet.

## Claims

### Claim 1

A tablet comprising 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butoxy]-1H-quinolin-2-one or a salt thereof as an active ingredient, an excipient (a), a binder (b), a disintegrant (c), a lubricant (d), and a coating, wherein the uncoated tablet comprises:
0.05 to 25% by weight of 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butoxy]-1H-quinolin-2-one or a salt thereof,
10 to 98.5% by weight of the excipient (a), which is at least one member selected from the group consisting of lactose, corn starch, and microcrystalline cellulose;
0.1 to 20% by weight of the binder (b), which is hydroxypropyl cellulose;
1 to 25% by weight of the disintegrant (c), which is at least one member selected from the group consisting of low-substituted hydroxypropyl cellulose, croscarmellose sodium, and sodium carboxymethyl starch; and
