Unnecessary diuretic therapy in the elderly

M G Myers, M E Weingert, R H Fisher

    Age and Ageing
    |November 1, 1982
    PubMed
    Summary

    Long-term diuretic use in the elderly showed no significant benefit and may not be necessary. Placebo groups experienced better serum creatinine, cholesterol, potassium, and BUN levels, suggesting caution with chronic diuretic prescriptions.

    Area of Science:

    • Geriatrics
    • Pharmacology
    • Internal Medicine

    Background:

    • Elderly populations often receive long-term diuretic therapy.
    • The necessity and safety of chronic diuretic use in older adults require further investigation.
    • Diuretics are commonly prescribed for conditions like hypertension and congestive heart failure (CHF).

    Purpose of the Study:

    • To evaluate the beneficial or adverse effects of long-term diuretic use in the elderly.
    • To determine if chronic diuretic therapy is necessary for older individuals without an immediate need.
    • To assess the impact of diuretics on cardiovascular parameters and metabolic markers in the elderly.

    Main Methods:

    • A double-blind, randomized, placebo-controlled trial was conducted over one year.
    • Sixty males and 17 females (mean age 80.0 and 84.3 years, respectively) were included.
    • Subjects were stratified for prior hypertension or congestive heart failure (CHF) and randomly assigned to placebo or active diuretic groups.

    Main Results:

    • Mean blood pressure (BP), heart rate, and weight remained similar to baseline in both groups after one year.
    • Congestive heart failure (CHF) developed in six active-group subjects and two placebo-group subjects.
    • Placebo subjects showed significant improvements in serum creatinine, cholesterol, potassium, and blood urea nitrogen (BUN).

    Conclusions:

    • Chronic diuretic use did not significantly alter the occurrence of CHF or hypertension in this elderly cohort.
    • The findings suggest that long-term diuretic therapy may not be necessary for elderly individuals without a clear indication.
    • Further research is warranted to optimize medication use in geriatric populations.
