Description
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.
Indication
For the treatment of bacterial infections (usually in combination with quinupristin).
Pharmacology
Dalfopristin is a streptogramin antibiotic, derived from pristinamycin IIA.
Affected Organisms
Enteric bacteria and other eubacteria
Biotransformation
Converted to an active non-conjugated metabolite by hydrolysis.
Half Life
The elimination half-life is approximately 0.70 hours.
Protein Binding
Moderate
