CRYSTALLINE MODIFICATION OF 2,4-DIOXO-6-METHYL-1,2,3,4-TETRAHYDROPYRIMIDINE, METHOD OF OBTAINING THE SAME AND A PHARMACEUTICAL PREPARATION BASED ON IT.

摘要

A new crystalline modification of 2,4-dioxo-6-methyl-1,2,3,4-tetrahydropyrimidine is disclosed, characterized by the interplanar distances (d) and relative reflex intensity (I). The process for obtaining the said substance involves using a cooling agent to cool a solution of 2,4-dioxo-6-methyl-1,2,3,4-tetrahydropyrimidine in water, an organic solvent or a mixture of both, at a rate of at least 6 DEG C per minute until the solution has completely crystallized. The crystals obtained are then removed and dried. The substance claimed has anti-inflammatory properties and promotes the healing of wounds and is the active substance in a preparation used in treating burns and wounds of various types.
