      Drug Name Ziprasidone Amphotericin B (liposomal)
      Mechanism 1 Prolong QT interval Hypokalemia
      Key Mechanism Factor 1
Factor Name Ventricular arrhythmias
Factor Description Ventricular arrhythmias are abnormal heart rhythms that cause your heart's lower chambers to pump blood instead of pumping it. This can limit or stop your heart from supplying blood to your body. While some of these arrhythmias are harmless and do not cause symptoms, others can have serious, even fatal, effects on your body.
      Mechanism Description
  • Increased risk of ventricular arrhythmias by the combination of Ziprasidone and Amphotericin B (liposomal) 
      Mechanism 2 Prolong QT interval Hypomagnesemia

Recommended Action
      Management Caution is advised when ziprasidone must be used concomitantly with medications that can cause potassium and/or magnesium disturbances. Serum electrolytes should be monitored and any abnormalities corrected prior to initiating therapy with ziprasidone.
