Coated preparation of the present invention can be easily by following manufacture method manufacturing, the method is characterized in that with dry process or damp process comprising medical compounds, particularly have below the about 40 weight % of medical compounds of unpleasant taste, about 5～about 25 weight % of waxy substance and the about 5～about 35 weight % of water-swellable material, if desired, also has binding agent, lubricant, correctives, the mixed-powder of other additive such as coloring agent carries out pelletize, granulate, be adjusted to particle diameter arbitrarily, heat treated then, waxy substance is worked as binding agent, further add the about 5～about 25 weight % of Powdered waxy substance, carry out the heating and melting coating.
The mixing of each powder composition, pelletize, granulate can carry out according to conventional method.For example in the occasion of using dry process; the pelletize of powder is following to be carried out: with press such as tablet machine, roll compaction machines; under the pressure of 50～100MPa; be compressed into strip, lamellar, be adjusted to granularity arbitrarily such as 350～1410 μ m (granule), 75～500 μ m (granula subtilis) with pallet formula pelletizing machine then.Infer that the plain granule with this manufacture method gained (refers to the granule that heat treated is preceding.Down together.), constituent waxy substance, water-swellable material homodisperse and the part by the compression waxy substance extend.
Then, heat treated should the element granule after, add Powdered waxy substance, prepare heat fusing coating granule thus and (refer to the granule after carrying out the wax Cotton seeds under the heating.Down together.)。
In heat fusing coating operation, the heating of Powdered waxy substance before interpolation and when adding carried out time enough under the softening required abundant temperature of interior interpolation waxy substance.Heating-up temperature is about more than 40 ℃ usually, preferably below the fusing point of interior interpolation waxy substance.That is, heating-up temperature is added waxy substance in this operation and can be got final product more than the temperature on moistening plain granule surface.Handle by this, fused interior interpolation waxy substance adds waxy substance outside the surface conduct of plain granule binding agent works.Therefore, heating-up temperature changes because of the fusing point of interior interpolation waxy substance.In add waxy substance at preferred about 40～about 90 ℃, preferred about especially 50～about 85 ℃ of softening getting final product.
Adding heating behind the Powdered waxy substance adds outside under the softening required abundant temperature of waxy substance and carries out time enough.Heating-up temperature is about more than 40 ℃ usually, preferably adds outside below the fusing point of waxy substance.Therefore, heating-up temperature changes because of the outer fusing point that adds waxy substance.The outer waxy substance that adds is at preferred about 40～about 90 ℃, preferred about especially 50～about 85 ℃ of softening down getting final product.
In heat fusing coating operation, the occasion that heating-up temperature is too high, interior interpolation waxy substance and the outer waxy substance that adds melt fully, waxy substance becomes fully to particulate coating, so granule is difficult to disintegrate in vivo, in be bundled into the stripping property reduction of branch.On the contrary, the occasion that heating-up temperature is low excessively, interior interpolation waxy substance does not work as the outer binding agent that adds waxy substance, also have, the outer waxy substance that adds does not fully extend on plain granule surface, and therefore particulate coating becomes very few, is suppressed at intraoral oozing out and becomes insufficient.
When heating-up temperature reaches thermophilic, add Powdered waxy substance, implement the heat fusing coating on plain granule surface.Preferably about 10～about 90 minutes of coating time, preferred about 20～about 60 minutes especially.The device that is suitable for the heat fusing coating can be enumerated the fluidized bed drying device.
Usually, carry out the occasion of powder coating, evenly carry out very difficulty of coating with fluidized bed.But,,, also can pass through fluidized bed drying device (Off ロ one ユ one one FLO-5 type even inhomogeneous when adding Powdered waxy substance by using this method; Great river former making institute) under heating, make it mobile, thus that waxy substance is softening, in the surface extension of plain granule, homogenization.Thus, this law provides very easy outside coating method.
