Bacitracin is an antibiotic injection used to treat pneumonia and empyema in infants, infections caused by the staphylococci bacteria and other infections that cause a pus build-up between the lungs and the covering membrane. It works by inhibiting the synthesis of the bacterial cell walls by preventing the transfer of mucopeptides into these walls. This drug is generally used in the injection form. Topical drug is used to treat minor cuts and scrapes by working against the bacteria that causes them, while ophthalmic drug is used to treat bacterial infections of the eye.
