Used primarily as an antibacterial agent, it is effective against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). Commonly applied in topical formulations, it treats skin infections such as impetigo, folliculitis, and infected wounds. It is also used in nasal ointments to eliminate MRSA colonization in the nostrils, reducing the risk of surgical site infections. Its mechanism involves inhibiting bacterial protein synthesis, making it a valuable tool in managing localized bacterial infections.
