What is the normal therapeutic range for digoxin levels?

• A. 0.5-1.5 ng/mL
• B. 0.8-2.0 ng/mL
• C. 1.0-3.0 ng/mL
• D. 2.0-4.0 ng/mL

Answer: (B)

The normal therapeutic range for digoxin levels is indeed 0.8-2.0 ng/mL. This range is critical for ensuring that the medication is effective in managing conditions like heart failure and atrial fibrillation without causing toxicity. Digoxin works by increasing the force of heart contractions and regulating heart rhythms, making monitoring its levels essential. Levels below 0.8 ng/mL can be insufficient for therapeutic effects, while levels above 2.0 ng/mL increase the risk of toxicity, which can lead to severe complications such as arrhythmias or gastrointestinal disturbance. Thus, maintaining digoxin in this therapeutic range is vital for patient safety and therapeutic efficacy in heart failure management.
