Background

  • Cyclic lipopeptide antibiotic that is active against Gram-positive bacteria

Mechanism of Action

  • Mechanism of action is to depolarize the cell membrane

Pharmacokinetics and Pharmacodynamics

  • Distributes well into soft tissues and musculoskeletal system, as well as urine
    • Poor CNS penetration1
    • Good lung penetration, but is inactivated by lung surfactant and should not be used to treat pneumonia
  • Bactericidal
  • Concentration-dependent, best predicted by AUC24:MIC

Dosing

Renal Dosing

CrCl (mL/min) Routine Dose High Dose
≥30 6 mg/kg IV q24h 8-10 mg/kg IV q24h
>30 6 mg/kg IV q48h 8 mg/kg IV q48h
HD 6 mg/kg IV q48h, dosed after dialysis 8 mg/kg IV q48h, dosed after dialysis
CRRT 6 mg/kg IV q48h 8 mg/kg IV q48h

Safety

  • Consider reducing or holding any statins while on daptomycin
  • Monitor CK
  • Monitor for eosinophilic pneumonitis
