The active ingredient in erythromycin is erythromycin itself, which is derived from the bacterium Saccharopolyspora erythraea (formerly known as Streptomyces erythreus). The compound works by inhibiting bacterial protein synthesis, which ultimately leads to the cessation of bacterial growth and replication. Beyond the active ingredient, erythromycin formulations often include several excipients or inactive ingredients that aid in the medication's stability, absorption, and overall efficacy.
