    Area of Science:

    • Pharmacology
    • General Practice
    • Clinical Chemistry

    Background:

    • Digoxin is a commonly prescribed medication in general practice.
    • Monitoring digoxin levels is crucial for ensuring therapeutic efficacy and minimizing toxicity.
    • Variability in patient adherence and metabolism can affect digoxin concentrations.

    Purpose of the Study:

    • To evaluate the utility of serum digoxin level estimations in a general practice setting.
    • To determine the prevalence of supratherapeutic digoxin levels.
    • To assess the impact of digoxin level monitoring on dose adjustments.

    Main Methods:

    • A cohort of patients prescribed digoxin in a general practice was identified.
    • Serum urea, creatinine, electrolytes, and digoxin concentrations were measured.

    Related Experiment Videos

  • Patient data, including adherence and dose adjustments, were analyzed.
  • Main Results:

    • Sixty-six patients were identified on digoxin therapy (0.73% of the practice population).
    • After excluding unreliable tablet-takers, 2 patients had supratherapeutic digoxin levels.
    • Dose alterations were made for 23 patients (38%), with 8 having digoxin discontinued.

    Conclusions:

    • Serum digoxin estimations are valuable tools for optimizing digoxin dosage in general practice.
    • Monitoring digoxin levels can identify patients at risk of toxicity or sub-therapeutic dosing.
    • Routine assessment of digoxin levels can lead to significant medication adjustments and improved patient outcomes.
