Background:

Dalfopristin is a semi-synthetic streptogramin antibiotic. Quinupristin/Dalfopristin (Q/D) is a valuable alternative antibiotic to vancomycin for the treatment of multi-drug resistant Enterococcus faecium infections.

Quinupristin/Dalfopristin(Q/D) is a combination of streptogramins B (Quinupristin) and streptogramins A (Dalfopristin) at 30:70 ratio[1]. Quinupristin/Dalfopristin, a semisynthetic injectable streptogramin, is a combination of 2 synergistic antibiotic components that are derived from pristinamycin: a type B streptogramin (Quinupristin) and a type A streptogramin (Dalfopristin), in a 30:70 weight-to-weight ratio[2].
