Glycopeptide antibiotics are a class of antibiotics that inhibit bacterial cell wall synthesis. They are particularly effective against Gram-positive bacteria, including strains resistant to other antibiotics, such as methicillin-resistant Staphylococcus aureus (MRSA). Common examples include vancomycin and teicoplanin. These antibiotics are typically administered intravenously for serious infections, as they are poorly absorbed in the gastrointestinal tract. While effective, their use can lead to side effects, including nephrotoxicity and ototoxicity, necessitating careful monitoring during treatment. Glycopeptide antibiotics play a crucial role in modern medicine, especially in treating severe bacterial infections.
