摘要:
The present invention provides the following capsule preparation, which is superior in dissolution property and the like of a pharmaceutically active ingredient and contains liquid and solid pharmaceutically active ingredients: a seamless capsule containing liquid and solid pharmaceutically active ingredients, wherein the liquid pharmaceutically active ingredient is encapsulated in the form of a liquid pharmaceutical composition, and the solid pharmaceutically active ingredient is dispersed in a capsule shell layer.
摘要:
The present invention aims to provide a seamless capsule free of an interfacial tension modifier and a gelling agent. The present invention provides a shell formed by a shell composition containing gelatin and a plasticizer, but free of an interfacial tension modifier and a gelling agent, and a seamless capsule comprising a capsule content free of an interfacial tension modifier and a gelling agent.
摘要:
Disclosed is a sustained-release preparation which is prepared by shaping a granule comprising a blood coagulation factor Xa inhibitor and a mixture of at least two hydrophilic polymers. Also disclosed is a pharmaceutical composition comprising a combination of the sustained-release preparation and an immediate release preparation comprising a blood coagulation factor Xa inhibitor. It becomes possible to provide a controlled release preparation comprising a blood coagulation factor Xa inhibitor for the prevention or treatment of thrombosis, which can control the activity of blood coagulation factor Xa for a long term and is excellent in convenience and compliance. It is also becomes possible to provide a method for producing the controlled release preparation.
摘要:
The solid preparation of the present invention aims at providing a solid preparation superior in the stability during production and preservation even when a poorly water-soluble substance having a low melting point is contained in a large amount, and also superior in the disintegration property and release property of a poorly water-soluble substance having a low melting point, after oral administration, and is characterized by the following 1) to 3): 1) containing a poorly water-soluble substance having a low melting point, a saccharide, and a cellulose selected from a crystalline cellulose and a low-substituted hydroxypropylcellulose, 2) a saccharide/cellulose weight ratio exceeding 2, and 3) a cellulose content of not less than 5 wt %.
摘要:
D-mannitol having a specific surface area of not less than about 1 m2/g is disclosed. The D-mannitol shows improved compressibility and is useful as an excipient.
摘要:
A process for advantageously producing tablets having an improved release property and an excellent stability to change with time is provided. The process is for producing tablets containing a morphinan compound represented by the Formula (I) below or pharmaceutically acceptable acid addition salt thereof and an acidic substance such as fumaric acid, maleic acid or adipic acid, and characterized in that the morphinan compound or a pharmaceutically acceptable acid addition salt thereof is granulated by wet granulation together with (an) excipient(s) prior to adding the acidic substance thereto.
摘要:
A catalyst composition for the hydrotreatment of hydrocarbon oils is disclosed. The composition comprises at least one metal compound having hydrogenating activity belonging to a Group VIB or Group VIII carried on a carrier comprising 2-35% by weight of zeolite and 98-65% by weight of alumina or an alumina-containing substance, wherein, (A) said alumina or alumina-containing substance (1) has a mean pore diameter of 60-125 angstrom and (2) contains the pore volume of which the diameter falls within .+-.10 angstrom of the mean pore diameter of 70-98% of the total pore volume, (B) said zeolite (3) has a mean particle size of 6 .mu.m or smaller and (4) contains particles of which the diameter is 6 .mu.m or smaller of 70-98% of all zeolite particles. It has both high hydrodesulfurization and high cracking capabilities at the same time, and can selectively crack the heavy fractions which have once been hydrotreated, yielding lighter fractions.
