Method for increasing the proportion of a crystalline organic compound which remains uncrystallized in a composite particulate product and suppressing recrystallization

---

Abstract

---

A method for increasing the proportion of a crystalline organic compound which remains amorphous and suppressing recrystallization in which a crystalline organic compound and a hydrophilic polymer substance are fixed onto a surface of core particles by means of impacts applied in a high velocity gas stream. The solubility and stability of the resulting composite product, such as a drug for internal use, can be improved.
