  • Patent number: 11213486
    Abstract: The drug-containing fat emulsion of the present invention, which comprises at least a slightly water soluble drug, an oil or fat, an emulsifier, and water as components, is characterized by having a content of the oil or fat of 2 to 120 mg/mL (excluding 2 mg/mL), having a weight ratio of the drug to the oil or fat (drug/(oil or fat)) of 0.001 to 20 (provided that the total content of the drug and the oil or fat is at most 125 mg/mL), having a content of lecithin as the emulsifier of 50 to 200 mg/mL (in which 50% by weight or less of the used lecithin is optionally replaced by an emulsifier other than lecithin), and having a turbidity of 0.5 or lower.

  • Publication number: 20210069110
    Abstract: An object of the present invention is to provide a non-aqueous composition having a drug carried therein, the composition being capable of preparing a drug-containing fat emulsion that is usable as an injection, an eye drop, a nasal drop, an inhalant, or the like by being mixed with an aqueous medium in use without producing a drug-containing fat emulsion in advance, and a method for producing the non-aqueous composition. The non-aqueous composition having a drug carried therein of the present invention as a resolution for achieving the object is characterized by comprising an oil or fat, a slightly water soluble drug, and an emulsifier which are dissolved in a polyhydric alcohol as a water soluble carrier at a content of the oil or fat of 0.05 to 250 mg/g, a weight ratio of the slightly water soluble drug to the oil or fat (slightly water soluble drug/(oil or fat)) of 0.

  • Publication number: 20180177820
    Abstract: An object of the present invention is to provide a protective composition for gastrointestinal mucosa, for example, for inhibiting occurrence of a gastrointestinal mucosa disorder when an oral drug that induces the gastrointestinal mucosa disorder is taken. The protective composition for gastrointestinal mucosa of the present invention as a resolution for achieving the object is characterized by comprising at least a macromolecular polysaccharide, sodium hydrogen carbonate and/or magnesium carbonate, and a polyhydric alcohol. According to the protective composition for gastrointestinal mucosa of the present invention, sodium hydrogen carbonate or magnesium carbonate foams through contact with a gastric juice in stomach to thereby generate diffusing power for the macromolecular polysaccharide. This power can allow the macromolecular polysaccharide to quickly dissolve or disperse in the gastric juice and allow the macromolecular polysaccharide to effectively exert a gastric mucosa protective action.

  • Publication number: 20160287627
    Abstract: [Problem] To suppress the onset of adverse effects of drugs that cause gastric ulcers as an adverse effect. [Solution] The onset of gastric ulcers induced by a drug is suppressed by incorporating, into a pharmaceutical composition containing a drug having gastric ulcers as an adverse effect, a high-molecular polysaccharide that has a molecular weight of 800,000-3,000,000 and that produces a gel when a 0.3% aqueous solution thereof is added dropwise to artificial gastric juice.
