Daptomycin

Daptomycin is a powerful antibiotic used to treat serious bacterial infections, particularly those caused by gram-positive bacteria. It is especially effective against resistant strains like Methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). Daptomycin works by disrupting the bacterial cell membrane, ultimately leading to bacterial cell death. It is usually administered via injection under medical supervision and is reserved for complicated infections such as bloodstream infections, endocarditis, and skin structure infections.

Uses of Daptomycin

• Treatment of complicated skin and soft tissue infections
• Bacteremia (bloodstream infections)
• Right-sided infective endocarditis caused by Staphylococcus aureus
• Effective against MRSA and VRE infections
• Used when other antibiotics fail due to resistance

How Daptomycin Works

Daptomycin binds to bacterial membranes and causes rapid depolarization, leading to the inhibition of protein, DNA, and RNA synthesis, ultimately killing the bacteria.

Benefits of Daptomycin

• Effective against resistant bacterial strains
• Quick onset of bactericidal activity
• Useful in severe and complicated infections
• Low risk of cross-resistance with other antibiotics
• Administered once daily due to long half-life

How to Take Daptomycin

Daptomycin is given as an intravenous (IV) injection, usually once daily, by a healthcare professional. Dosage and duration depend on the type and severity of the infection. Do not self-administer.
