Adverse Reactions

Serious

  • Asystole (case reported) [3]
  • Fat embolism
  • Hypersensitivity reactions

  • Metabolism:
  • Excretion:
  • Mechanism of Action:
    • Emulsion acts as a “lipid sink,” surrounding a lipophilic drug molecule and rendering it ineffective
    • Fatty acids from the ILE provide the myocardium with a ready energy source, improving cardiac function
