ABSTRACT
In this study melting thermodynamic characteristics of clarithromycin and metronidazole as individualsubstances were investigated by DSC method. It was found that the binary system of clarithromycin andmetronidazole is a system with simple eutectic. Composition, melting temperature and the heat of fusionof the eutectic were determined by calculation and experimental methods.
