[0204] During the preparation of the coated tablet (A), it is preferable to form an inactive intermediate layer between the inner core and the outer layer to avoid direct contact between the inner core and the outer layer. The intermediate layer contains, for example, the above-mentioned coating base and coating additives. The intermediate layer preferably comprises an aqueous film coating base (preferably hydroxypropylmethylcellulose) and an opacifier and / or colorant (preferably talc).
[0205] In the above-mentioned coated tablet (A), the outer layer is formed at a ratio of preferably 0.1-100 parts by weight, more preferably 1-50 parts by weight, still more preferably 3-30 parts by weight, relative to 100 parts by weight of the inner core.
[0206] Moreover, in the above-mentioned coated tablet (A), the intermediate layer is formed at a ratio of preferably 0.1-30 parts by weight, more preferably 0.5-20 parts by weight, still more preferably 1-5 parts by weight, relative to 1...
