Azithromycin is a second-generation semi-synthetic macrolide antibiotic with broad-spectrum activity against Gram-positive and Gram-negative bacteria, anaerobes, Mycoplasma, and Chlamydia. It is acid-stable, has a long half-life, high bioavailability, extensive tissue distribution, and acts by inhibiting bacterial protein synthesis.
