Erythromycin is a macrolide antibiotic. It is mainly used as a veterinary drug for the infection of gram-positive
bacteria and mycoplasma.
It is more used as an initial raw material for the synthesis of erythromycin, roxithromycin, azithromycin, Macrolide antibiotics such as clarithromycin.
Function & Application
1. erythromycin can affect protein synthesis of bacteria, the general effective against gram positive bacteria, mainly used for the treatment of G caused by penicillin resistant Staphylococcus aureus infection.
2. erythromycin is macrolide antibiotics commonly used, antibacterial spectrum similarity with penicillin, mainly used for patients allergic to penicillin, or of penicillin resistant Staphylococcus aureus infection, can also be used for Streptococcus, pneumococcus infection and diphtheria carrier.
3. this is the large rin g lactone class antibiotic derivatives intermediates of bacteriostatic antibiotics, antibacterial spectrum was similar to green bacteria.
