A derivative of erythromycin, Roxithromycin is a semi-synthetic macrolide antibiotic. It works by interfering with the protein synthesis, thereby preventing the bacteria from growing.Reference standards of Roxithromycin API,and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
