Erythromycin antibiotics are strictly macrolide
antibiotics. They are fast bacteriostatic drugs, including erythromycin, mdicomycin, acetylspiramycin, and josamycin. Main treatments: aerobic Gram-positive bacteria, Legionella, Campylobacter, Chlamydia, Mycoplasma, certain anaerobic bacteria, Mycobacterium and Toxoplasma. Newer drugs, ie, new macrolides, include roxithromycin, azithromycin, and clarithromycin. The antibacterial spectrum and bacteriostatic effect of these drugs are similar to those of erythromycin, but the half-life is extended, which can reduce the number of administrations, reduce the dosage and reduce adverse reactions.
