Characterization of th physical properties of binary system of eryhromycin stearate (ERS)-sodium starch glycolate(SSG) due to compression force, had been caried out. The solid state properties were evaluated by powder X-ray diffraction (PXRD), scanning electron microscope (SEM) and differentail thermal analysis (DTA) methods. The weight microscope (SEM) and differential thermal analysis (DTA) …
