摘要:
A composition containing an extremely poorly water-soluble drug and obtained by treating, with a supercritical fluid or subcritical fluid of carbon dioxide, a mixture comprising a porous silica material and the extremely poorly water-soluble drug; and its production process. The porous silica material has an average pore diameter in a range of from 1 to 20 nm, pores having diameters within ±40% of the average pore size account for at least 60% of a total pore volume of the porous silica material, and in X-ray diffractometry, the porous silica material has at least one peak at a position of diffraction angle (2θ) corresponding to a d value of at least 1 nm.The composition according to the present invention, which contains the extremely poorly water-soluble drug, is excellent in the dissolution of the extremely poorly water-soluble drug.
摘要:
The present invention provides an indomethacin-containing external liquid preparation which provides good feeling of use, which exhibits high percutaneous absorption of indomethacin, and which, particularly in a low-temperature environment, does not cause precipitation of crystals with time.The present invention is drawn to an external liquid preparation containing indomethacin, a lower alcohol, water, a sulfite, and polyethylene glycol having an average molecular weight of 3,000 to 15,000.
摘要:
A composition containing a very low water-soluble drug, which composition is produced by treating, with a supercritical or subcritical carbon dioxide fluid, a mixture containing a very low water-soluble drug and a porous material (exclusive of a porous silica material characterized in that the material has an average pore diameter of 1 to 20 nm, the total pore volume of the material that have a diameter falling within a range of ±40% of the average pore diameter account for 60% or more the volume of all the pores of the material, and, when subjected to X-ray diffractometry, the material exhibits one or more peaks at a diffraction angle (2θ) corresponding to d of 1 nm or more); and a method for producing the composition.The very-low-water-soluble-drug-containing composition of the present invention ensures improved dissolution of the very low water-soluble drug.
