    How does Azithromycin work?

    Azithromycin tablets belong to a group of drugs known as macrolide antibiotics. They work by preventing bacteria from making their proteins.

The bacteria in due course of the intake of the medicine become inactive and are unable to affect the immune system. Thus, the infection gets healed in the patient. Azithromycin is an antibiotic drug which is helpful in clearing up infections caused by a comprehensive variety of bacteria. The popular brand names of Azithromycin include Clamelle and Zithromax.
