What is the typical therapeutic range for digoxin in ng/mL?

The typical therapeutic range for digoxin is considered to be between 0.5 to 0.8 ng/mL, making this the correct choice. This range is crucial for achieving the desired effects of digoxin, which is primarily used for conditions such as heart failure and atrial fibrillation. Maintaining blood levels within this therapeutic range helps ensure that the medication is effective without causing toxicity.

Higher levels above this range can lead to digoxin toxicity, which manifests in various symptoms including gastrointestinal issues, visual disturbances, and cardiac arrhythmias. On the other hand, levels below the therapeutic range may not provide adequate treatment, leading to uncontrolled heart failure or other complications.

Understanding this therapeutic window is essential for healthcare providers when monitoring patients on digoxin therapy to ensure optimal dosing and patient safety.
