Inventor: MAZAKI NORIO
IPC: A61K9/00
Filed: 1992-03-05
Abstract: PURPOSE:To provide a process for easily producing a crystal having improved dissolution rate, especially a process for increasing the dissolution rate of a sparingly soluble drug crystal and converting the crystal to a drug crystal having high solubility. CONSTITUTION:The crystal of the substance to be produced by the present process has differences in the solubility and the dissolution rate by the crystal planes and the crystal plane having relatively high solubility coincides with the crystal plane having relatively high dissolution rate. The crystal of the substance is placed in a solution of the substance having a concentration adjusted to a level between the solubility of a crystal plane and that of the other crystal plane. The crystal plane having high solubility is preferentially dissolved by this process to increase the ratio of the crystal plane to the total crystal surface area.
