Quinupristin-dalfopristin (Cat.No:M118102) is a combination antibiotic used to treat infections caused by multidrug-resistant bacteria, particularly strains of Gram-positive cocci like methicillin-resistant Staphylococcus aureus (MRSA). It works by inhibiting bacterial protein synthesis. This drug is primarily administered intravenously and is employed when other antibiotics have proven ineffective.
