Digoxin: its role in contemporary medicine

Area of Science:

• Cardiology
• Pharmacology
• Medical History

Background:

• Digoxin, derived from foxglove, has been used therapeutically for over two centuries.
• Its use predates modern evidence-based medicine and mechanistic understanding.
• Historically vital for heart failure and atrial tachyarrhythmias.

Observation:

• Recent decades show growing evidence questioning digoxin's safety and efficacy.
• Alternative treatments for heart failure and arrhythmias demonstrate superior safety and effectiveness.
• Digoxin's mechanism of action was not initially understood.

Findings:

• Mounting evidence challenges the established safety and efficacy profile of digoxin.
• Newer pharmacotherapies offer improved outcomes for heart failure and atrial tachyarrhythmias.
• Digoxin's historical therapeutic role is now subject to significant re-evaluation.

Implications:

• Digoxin's contemporary role in pharmacotherapeutics is controversial.
• Its use should be restricted to select patients and clinical scenarios.
• Careful monitoring of serum digoxin concentrations is crucial for safe administration.
