Why might pimobendan be a better option than digoxin when choosing an inotropic agent?
Digoxin has a narrow therapeutic index and can cause life threatenting arrhythmia if the patient is given too much and is not being closely monitored. Pimobendan is overall well tolerated in dogs and has overall less severe side effects.
