Roxithromycin can be used to treat inflammation of the tonsils. Roxithromycin is a new generation of macrolide antibiotic, which acts as an antibacterial agent mainly by inhibiting bacterial protein synthesis. Roxithromycin has good antibacterial activity against common pathogenic bacteria of respiratory and skin infections, such as Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Streptococcus pyogenes, Mycoplasma pneumoniae and Legionella. The clinical manifestations of tonsillitis are pharyngeal discomfort, pain, foreign body sensation, dryness, itching, irritating cough, etc. The pathogenic bacteria are streptococci and staphylococci most commonly, both of which are sensitive to roxithromycin, so roxithromycin can treat inflammation of tonsils.
