Azithromycin is an azalide, a subclass of macrolide antibiotics. Azithromycin is one of the world's best-selling antibiotics, marketed in the United States under the name Zithromax, and under a variety of brand names and generic labels worldwide. It is derived from erythromycin; however, it differs in chemical structure from erythromycin in that a methyl-substituted nitrogen atom is incorporated into the lactone ring, thus making the lactone ring 15-membered.
