Daptomycin (Cubicin)

Cubicin, LY146032, Cidecin

Cyclic lipopeptide antibiotic from Streptomyces roseosporus (1980s), approved by the FDA and EMA for complicated skin infections and bacteremia, including MRSA and right-sided endocarditis. Kills bacteria in both growing and stationary phases via a distinctive membrane-disrupting mechanism that resists cross-resistance.

Research score 95/100. Reference only, not a dose.

Mechanism

Calcium-dependently inserts into bacterial membranes, binding phosphatidylglycerol to trigger depolarization and potassium efflux; pore/channel formation causes cellular leakage and death without targeting cell-wall or protein synthesis.

Safety file

Muscle toxicity (myopathy, rhabdomyolysis) is the main risk, requiring weekly CPK checks; rare eosinophilic pneumonia and peripheral neuropathy with long-term use are also reported.

  • Muscle pain
  • CPK elevation
  • Rhabdomyolysis
  • Peripheral neuropathy
  • Skin reactions
  • Gastrointestinal disturbances
