Cryosynthesis of nanosized drug substances

The specific features of cryochemical technology for producton of new nanosized modifications of drug substances are observed. The method is based on transformation of the initial substance in gas phase and followed by the organization of molecular flow to the cooled surfaces. The results of study of physicochemical properties of nanosized drug substances obtained for different applications are presented: cardiological carvedilol, cytostatic imatinibe mesilate, steroid hormone Δ 5 androstendiol-3β,17β, psychoactive phenasepam. On example of the last compound the results of biological tests are presented.
