💊 Profile

Pristinamycin is a streptogramin antibacterial produced by the growth of Streptomyces pristina spiralis, with actions and uses similar to those of virginiamycin. It is given orally in the treatment of susceptible infections, particularly staphylococcal infections, in a dose of 2 to 4 g daily in divided doses. It has been available for many years as an oral antistaphylococcal drug, and also acts against streptococci. It is effective against strains showing resistance to erythromycin; resistance to pristinamycin is rare,2,3 although resistance in staphylococci has been reported in the past.4,5 It is effective against meticillin-resistant Staphylococcus aureus (MRSA)6,7 but its usefulness in severe infection is limited by its poor solubility, which prevents development of an intravenous formulation. Oral pristinamycin has been shown to be as effective as standard therapy with intravenous then oral penicillin in the treatment of erysipelas.8 Mixtures of water-soluble derivatives of pristinamycins I and II, such as quinupristin/dalfopristin, are in clinical use or under investigation.
