Clarithromycin may be bacteriostatic or bactericidal depending on the organism and drug concentration. It is a semisynthetic macrolide antibiotic derived from erythromycin, inhibits bacterial protein synthesis by binding to the bacterial 50S ribosomal subunit. Binding inhibits peptidyl transferase activity and interferes with amino acid translocation during the translation and protein assembly process.. Reference standards of Clarithromycin API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below
