At the Department of Industrial Technology of Drugs suppositories for the treatment of degenerative and inflammatory diseases of the rectum have been developed; the active substance with the reparative activity – diacamph is included in their composition. The crystallographic characteristics of the diacamph original powder crystals, crushed diacamph crystals and suspensions of diacamph in propylene glycol have been studied. The optimal technology of diacamph introduction to the dosage form has been selected. Based on the thermogravimetric analysis the maximum heating temperature of the suppository mass has been determined, and the absence of interaction between the active substance and excipients in this dosage form has been proven. The research results will be used when developing the industrial technology for manufacturing suppositories.
