The effects of discontinuing long-term diuretic therapy in the elderly
Insights
Discontinuing long-term diuretic therapy in elderly patients showed minimal adverse effects, with most not requiring re-initiation. This suggests careful withdrawal can identify patients no longer needing these medications.
Area of Science:
- Geriatric Medicine
- Clinical Pharmacology
- Internal Medicine
Background:
- Long-term diuretic therapy is common in elderly patients, but its necessity may decrease over time.
- Discontinuation of chronic medications requires careful evaluation to avoid adverse events.
- Assessing the impact of stopping diuretics in older adults is crucial for optimizing treatment.
Purpose of the Study:
- To investigate the effects of discontinuing long-term diuretic therapy in elderly patients.
- To determine the safety and efficacy of withdrawing diuretics in a geriatric population.
- To identify patients who no longer require maintenance diuretic treatment.
Main Methods:
- A double-blind, randomized controlled trial was conducted with 141 elderly patients on maintenance diuretics.
- Patients were divided into two groups: continued diuretic therapy (52 patients) and placebo (54 patients).
- Outcomes were monitored over 12 weeks, assessing edema, potassium levels, blood pressure, and plasma urea.
Main Results:
- Eight patients in the placebo group required diuretic re-initiation within 12 weeks.
- A slight increase in ankle edema was observed in the placebo group.
- Diuretic group showed potential for hypokalemia and slight increase in plasma urea; placebo group showed slight blood pressure rise.
Conclusions:
- Discontinuation of long-term diuretic therapy in elderly patients can be undertaken safely under supervision.
- This approach helps identify individuals who no longer benefit from or require diuretics.
- Careful withdrawal allows for the identification of patients needing continued diuretic treatment, optimizing medication use.
Abstract:
The effects of discontinuing long-term diuretic therapy were investigated by means of a double-blind randomized controlled trial. A total of 141 elderly patients in the long-stay wards of six hospitals were found to be taking maintenance diuretics, and for 33 of these the drugs were judged to be mandatory. Of the remaining patients, 52 continued to receive diuretics while 54 were given matching placebo tablets. Eight in the latter group required diuretic therapy to be resumed during the following 12 weeks. The main change observed in patients who completed the trial was a slight increase of ankle oedema in the placebo group. Plasma potassium levels below 3.5 mEq/1 were found in some patients taking diuretics but not when the drugs had been withdrawn for 12 weeks. Blood pressure rose slightly in the placebo group and plasma urea rose slightly in the diuretic group. It was concluded that old people receiving long-term diuretic therapy without obvious current indication should have the drugs withdrawn under careful supervision so that those needing them could be identified.
