- enteric or sustained-release iodide such as ibudilast, tamsulosin hydrochloride, -cardipine hydrochloride, val-dipine hydrochloride, mouth oxatidine acetate hydrochloride, theophylline, -fedipin, hemedastin fumarate, pranlukast or lansoprazole may be mentioned. .
- Production Example 1 of the present invention in which the inner core was a mixture of microcapsules and granules having the same size and higher moldability than the microcapsules, the inner core was modified with an adhesive component on the surface of the microcapsules.
- Production Example 2 which is the product of the present invention, Comparative Production Example 1, in which the inner core is sandwiched in layers with microcapsules and excipients to give a dry-coated tablet,
- the moldability of the tablet and the presence or absence of breakage of the microcapsules were evaluated.
- the evaluation of microcapsule destruction was performed by the following method.
- a tablet containing vitamin E-containing microcapsules is molded, and immediately after molding, vitamin E (tocopherol) exudes and the tablet surface is colored! / The determination was made by visual observation as to whether or not it was correct.
- lactose 'crystalline cellulose 40 mg (same as above) Supply lOOmg, and move the upper center punch and lower center punch toward each other, and in the next step, temporarily maintain the moldability to enable smooth transition. Molded.
- the lower punch lowered supply 70 mg of the remaining lactose 'crystalline cellulose granulated product (same as above) to and around the temporary molded product molded up to the previous process in the die.
- the lactose 'microcrystalline cellulose and microcapsules were temporarily encapsulated in the lactose' microcrystalline cellulose granulated product, and the upper and lower punches were moved toward each other, this time using a hydraulic node press.
- the tablets were compressed at a compression pressure of 7.9 kg / mm 2 per tablet unit area (approximately 400 kg per punch) using a press (same as above). It was confirmed that vitamin E did not seep out on the tablet surface and that the microcapsules were not broken.
- microcapsules (same as above) were supplied to the space on the lactose 'crystalline cellulose temporary molded product surrounded by the lower outer punch, and the upper center punch and the lower center punch were The specimens were moved in directions that are close to each other, and were manually temporarily compressed so that the surface became flat. Further, lactose 'crystalline cellulose granulated product (40 mg, same as above) was supplied to the space on the temporary molded product that was surrounded by the lower outer punch and molded by the previous step and had microcapsule strength. The lower center punches were moved in mutually adjacent directions, and were manually temporarily compressed so that the surface became flat.
- Tableting was performed using a press (same as above) at a compression pressure of 7.9 kg / mm 2 per tablet unit area (approximately 400 kg per punch). No bleeding of vitamin E was observed on the tablet surface. It was confirmed that microcapsules were not broken.
- micro force capsule (as above) is supplied to the space above the lactose 'crystalline cellulose temporary molded product surrounded by the lower outer punch, and the upper center punch and the lower center punch are supplied.
- the punches were moved in mutually opposite directions and, in the next step, were preliminarily molded to such an extent that moldability enabling smooth transition could be maintained.
- the lower punch lowered supply 85 mg of the remaining lactose 'crystalline cellulose granulated product (same as above) to and around the temporary molded product molded up to the previous process in the die.
- the lactose crystalline cellulose and the microcapsules were temporarily encapsulated in the lactose crystalline cellulose granules, and the upper and lower punches were moved in mutually opposing directions.
- the tablets were compressed at a compression pressure of 7.9 kg / mm 2 per tablet unit area (approximately 400 kg per punch) using a press machine (same as above).
- the tablet had large cracks on the side surface (circumferential surface) of the tablet at the time of tablet removal, and disintegrated into a layer at the time of tablet removal or when grasped by hand after removal.
- a small amount of microcapsules was present on a part of the side surface of the tablet.
