摘要:
Provided is a process for producing spherical base granules comprising a easily water-soluble drug and suited for film coating by spraying a layering liquid over pharmaceutically inert spherical core particles, thereby coating the particles with a layer comprising the easily water-soluble drug, wherein (1) the spherical core particles have a microcrystalline cellulose content of 30 mass% or greater and a water absorbing capacity of 0.5 cm 3 /g or greater; and (2) the layering liquid is an aqueous solution comprising at least the easily water-soluble drug and a low water-soluble saccharide.
摘要:
Spherical base granules comprising a hardly water-soluble drug and suited for film coating thereon are produced by layering spherical core particles with a drug-containing layering liquid comprising both micronized microcrystalline cellulose and an emulsifier therein and therefore having improved suspension stability.

Disclosed is a solid preparation which comprises at least one active ingredient and at least one dissolution-controlling base substance and can be formed by compression molding, wherein the dissolution-controlling base substance contains 5.0 to 99.9% by weight (inclusive) of a modified starch having a moisture retaining capacity of 400% or more and a gel indentation load of 200 g or more, containing a water-soluble ingredient in an amount of 40 to 95% by weight, having particles passing through a 75 μm-mesh sieve in the proportion of 90% by weight or more and particles passing through a 32 μm-mesh sieve in the proportion of 20% by weight or more, and having an average particle diameter of not smaller than 20 μm and smaller than 50 μm.
摘要:
The characteristic in being coated with film of spherical elementary granules is improved by adjusting a short/long diameter-ratio distribution coefficient to a specific value.
摘要:
A process for producing a granule-containing tablet comprising mixing more than 25 mass% to 89 mass% or less of crystalline cellulose exhibiting a tensile displacement at break of 25 to 80 µm and a relative fluidity index of 2.15 to 2.80 at a maximum compaction stress of 15 kPa, 10 to 70 mass% of spherical granules, and 20 mass% or less of a disintegrant, and then compressing the obtained mixture.

摘要:
Disclosed is a cellooligosaccharide composition comprising, as the main ingredient, at least one cellooligosaccharide selected from the group consisting of cellobiose, cellotriose, cellotetraose, cellopentaose and cellohexaose, which is in the powdery form having an average L/D value of 3.0 or lower, a bulk density of 0.80 g/mL or lower and an angle of repose of 60° or lower.
