Cephradine is a cephalosporin antibiotic with broad spectrum bactericidal activity against both gram-positive and gram-negative bacteria. Cephradine interferes with the synthesis of bacterial cell wall by inhibiting transpeptidase enzyme. As a result the bacterial cell wall is weakened, the cell swells and then ruptures.
