Abstract:
1. A solid dispersion comprising: an active ingredient having a solubility in water at 25° C. of not more than 1 mg/mL, and a powdery porous carrier impregnated with and supporting the active ingredient, wherein the powdery porous carrier comprises a first porous silicon-containing carrier having a heating loss of not more than 2.5% by weight at a temperature of 950° C. for 2 hours, wherein the first porous silicon-containing carrier has a mean pore size of 15 to 20 nm, an oil absorption of 230 to 320 ml/100 g, a mean particle size of 3 to 15 μm, and a specific surface area of 400 to 600 m wherein the first porous silicon-containing carrier satisfies at least one of the following intensity ratios in an infrared absorption spectrum: wherein I wherein the powdery porous carrier further comprises a second porous silicon-containing carrier having a heating loss of not less than 4.5% by weight at a temperature of 950° C. for 2 hours.
