Plasma digoxin concentration in children with heart failure

Area of Science:

• Pediatric Cardiology
• Pharmacology
• Clinical Therapeutics

Background:

• Heart failure in children necessitates effective and safe medication regimens.
• Digoxin is a critical medication for managing pediatric heart failure.
• Establishing appropriate pediatric dosing is essential for therapeutic success.

Purpose of the Study:

• To present an effective and safe digoxin dosage schedule for children.
• To evaluate plasma digoxin concentrations in pediatric patients on maintenance therapy.
• To compare pediatric plasma digoxin concentrations with established adult therapeutic levels.

Main Methods:

• A specific digoxin dosage schedule was administered to pediatric patients with heart failure.
• Plasma digoxin concentrations were measured during maintenance therapy.
• Data were analyzed to assess safety, efficacy, and concentration levels.

Main Results:

• The presented digoxin dosage schedule proved effective and safe across various pediatric age groups.
• Maintenance plasma digoxin concentrations in children closely matched previously reported adult therapeutic levels.
• The results support the efficacy of the proposed twice-daily dosage regimen.

Conclusions:

• The developed digoxin dosage schedule offers a safe and effective treatment option for pediatric heart failure.
• The twice-daily regimen ensures therapeutic plasma digoxin concentrations comparable to adults.
• Further investigation into potentially higher, safe doses may be warranted.
