Why do we use erythromycin?
erythromycin is a type of antibiotic medication that is used to treat bacterial infections. It works by inhibiting the growth and spread of bacteria, which helps the body’s immune system to fight the infection.
erythromycin is primarily used to treat respiratory tract infections, such as pneumonia and bronchitis, as well as skin and soft tissue infections, such as cellulitis and impetigo. It can also be used to treat certain types of sexually transmitted infections, such as chlamydia.
