Erythromycin acts by inhibition of protein synthesis in susceptible
organisms by reversibly binding to
50 S ribosomal subunits, thereby inhibiting translocation of aminoacyl
transfer-RNA and inhibiting
polypeptide synthesis. Antagonism has been demonstrated _in vitro
_between erythromycin, lincomycin,
chloramphenicol, and clindamycin.
