Summary

Activated charcoal significantly enhances digoxin elimination in patients with digoxin toxicity. This treatment reduced the drug's elimination half-life by 47%, improving patient outcomes.

Area of Science:

  • Pharmacology
  • Clinical Toxicology

Background:

  • Digoxin toxicity is a significant clinical concern.
  • Activated charcoal has been suggested for treating chronic digoxin intoxication based on healthy volunteer studies.

Purpose of the Study:

  • To evaluate the effectiveness of activated charcoal in accelerating digoxin elimination in intoxicated patients under routine clinical conditions.

Main Methods:

  • Retrospective review of adult in-patient serum digoxin level requests (1991-1993) with levels > 2.5 ng/ml.
  • Comparison of digoxin elimination half-life and total body clearance between patients treated with activated charcoal and an untreated control group.

Main Results:

  • The activated charcoal group showed a significantly shorter digoxin elimination half-life (36 h vs. 68 h).

Related Experiment Videos

  • Total body clearance of digoxin increased by 78% in the activated charcoal group (98 ml/min vs. 55 ml/min).

    • Conclusions:

    • Activated charcoal administration effectively increases digoxin elimination in intoxicated patients.
    • This finding supports the use of activated charcoal as a therapeutic intervention for digoxin toxicity in clinical practice.
