Biochem/physiol Actions

Daptomycin is a natural cyclic lipopeptide antibiotic found in Streptomyces roseosporus. It is has been found to be effective in treating infections caused by aerobic Gram-positive bacteria. Daptomycin inhibits many antibiotic resistant strains such as methicillin-resistant S. aureus (MRSA), vancomycin-intermediate S. aureus (VISA) and vancomycin-resistant S. aureus (VRSA).

The mode of action of daptomycin is quite different from that of any other antibiotic. Daptomycin binds to bacterial membranes and causes a rapid depolarization of membrane potential. This loss of membrane potential causes inhibition of protein, DNA, and RNA synthesis, which results in bacterial cell death.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.
