Definitions
- the present invention relates to a composition containing a poorly soluble drug supported on a water-soluble polymer as a solid dispersion, and relates to a pharmaceutical composition showing rapid disintegration.
- compositions require not only the pharmacological properties of the pharmaceutically active ingredients but also their physicochemical properties, in order for the pharmaceutically active ingredients contained in the pharmaceutical preparations to effectively exhibit pharmacological effects and ameliorate and cure the intended indication. It goes without saying that it is necessary to select an appropriate dosage form and treatment depending on the target characteristics, the type of target indication, the disease state, and the like.
- poorly soluble drugs have low solubility in the gastrointestinal tract, they are generally not only poorly absorbed from the gastrointestinal tract but also cannot be expected to be fast-acting.
- drugs that become poorly soluble depending on pH are affected only by the pH in the gastrointestinal tract of the patient and the diet, so that only the bioavailability due to administration varies. In some cases, the immediate effect cannot be expected.
- a method for improving the solubility or absorbability of a poorly soluble drug a method of making the drug finer, a method of forming a solid dispersion, and the like are known. Among them, a method of forming a solid dispersion is particularly preferred. It is considered to be a practical general-purpose method for improving the solubility and absorbability of poorly soluble drugs (Japanese Patent Publication No. 59-48810 (corresponding patent US Pat. 5 6 4)).
- the method of forming a solid dispersion by supporting a poorly soluble drug on a polymer base is suitable for a composition for a sustained release formulation, but any polymer base capable of solid dispersion is used. Disintegration Since it does not contribute, the disintegration rate of the preparation by body fluid is slow, the dissolution of the drug is delayed, and rapid efficacy cannot be expected.
