Indication: This product is a broad-spectrum macrolide antibiotic, suitable for patients over 12 years old, used to treat mild and moderate infections caused by the following sensitive bacteria: Acute exacerbation of chronic bronchitis: caused by Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae. Acute bronchitis: caused by Moraxella catarrhalis and Streptococcus pneumoniae. Community-acquired pneumonia: caused by Legionella pneumophila, Mycoplasma pneumoniae, and Streptococcus pneumoniae. Nasopharyngitis and tonsillitis: caused by Streptococcus pyogenes. Simple skin and soft tissue infections: caused by Staphylococcus aureus (methicillin-sensitive strains) and Streptococcus pyogenes. Note: Dirithromycin is effective in treating nasopharyngitis caused by Streptococcus pyogenes and can eradicate it; there are no reports on the prevention of rheumatic fever.

Indication: Mild or moderate respiratory tract infections caused by β-hemolytic streptococci and pneumococci. Hemophilic influenza. Mild or moderate lower respiratory tract infections caused by β-hemolytic streptococci and pneumococci. Respiratory tract infections caused by Mycoplasma pneumoniae. Whooping cough caused by Bordetella pertussis: Erythromycin can effectively eliminate the whooping cough bacteria in the throat of patients. Clinical studies have shown that erythromycin can prevent susceptible people from being infected with whooping cough. Diphtheria: Diphtheria is caused by the toxin produced by Bordetella diphtheriae. Erythromycin can prevent susceptible people from becoming diphtheria carriers or eradicate the bacteria in carriers. Erythrasma caused by Corynebacterium microti. Intestinal amoeba caused by Entamoeba histolytica. Mononucleosis caused by Listeria. Mild and moderate infections of the skin and soft tissues caused by Streptococcus pyogenes and Staphylococcus aureus.
