  The present invention relates to a solid pharmaceutical composition containing a propionic acid or acetic acid non-steroidal anti-inflammatory drug, and a pharmaceutical preparation comprising the same.

  Propionic acid-based or acetic acid-based non-steroidal anti-inflammatory drugs are often poorly soluble drugs with low solubility in water. As a technique for improving the dissolution property of a poorly soluble drug and increasing the dissolution rate, a technique for forming a composition containing a poorly soluble drug and a polymer compound is known (Patent Document 1: JP-A-3-83922, Patent Document 2: Japanese Patent Application Laid-Open No. 8-291063).
