Norvancomycin hydrochloride is primarily used as an antibiotic to treat severe bacterial infections, particularly those caused by Gram-positive bacteria. It is effective against infections that are resistant to other antibiotics, such as methicillin-resistant Staphylococcus aureus (MRSA). This compound is often administered intravenously in hospital settings for serious conditions like sepsis, endocarditis, and bone or joint infections. It works by inhibiting cell wall synthesis in bacteria, leading to their destruction. Due to its potency, it is typically reserved for cases where other treatments have failed or are unsuitable. Proper dosage and monitoring are essential to minimize potential side effects, such as kidney toxicity or hearing loss.
