fusidic acid and its Impurities
An antibiotic which is derived from fungus Fusidium coccineum , Fusidic acid is bacteriostatic in nature. It works by preventing the protein synthesis. It shows action against both gram positive and gram negative strains. Reference standards of Fusidic Acid API,and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
