Dalfopristin
Dalfopristin is a combination of two antibiotics (Dalfopristin and quinupristin) used to treat infections by staphylococci and by vancomycin-resistant Enterococcus faecium. It is not effective against Enterococcus faecalis infections. Dalfopristin inhibits the early phase of protein synthesis in the bacterial ribosome and quinupristin inhibits the late phase of protein synthesis.
