Erythromycin is an oral macrolide antibiotic, produced by Streptomyces erythromycin. It can reversibly bind to the bacterial 50S ribosome and inhibit protein synthesis. Erythromycin is white or nearly white crystal or powder; odorless, bitter; slightly moist. Soluble in ethanol, very slightly soluble in water.
Erythromycin can affect the synthesis of proteins. Generally, bacteria are effective against Gram-positive bacteria and are mainly used to treat drug-resistant infections of penicillin G Staphylococcus aureus. Erythromycin is a common macrolide antibiotic with the similar antibacterial spectrum to penicillin. It is mainly used for allergic to penicillin patients, or for penicillin-resistant Staphylococcus aureus infection, and also for streptococcus, pneumococcal infection and diphtheria By.
