Used to treat community-acquired bacterial pneumonia (CABP) in adults. It works by stopping the growth of bacteria, particularly common pathogens like Streptococcus pneumoniae and Staphylococcus aureus. Administered either intravenously or orally, it offers a complete treatment course from hospital to home. Its mechanism targets bacterial protein synthesis with high specificity, reducing the risk of disrupting normal gut flora. Effective against multidrug-resistant strains, making it valuable in areas with high antibiotic resistance.
