Aldactone (Spironolactone) - Summary



Spironolactone has been shown to be a tumorigen in chronic toxicity studies in rats (see Precautions ). Aldactone should be used only in those conditions described under Indications and Usage . Unnecessary use of this drug should be avoided.



spironolactone tablets, USP

Aldactone oral tablets contain 25 mg, 50 mg, or 100 mg of the aldosterone antagonist spironolactone.

Aldactone (spironolactone) is indicated in the management of:

Primary hyperaldosteronism for:

Establishing the diagnosis of primary hyperaldosteronism by therapeutic trial.

Short-term preoperative treatment of patients with primary hyperaldosteronism.

Long-term maintenance therapy for patients with discrete aldosterone-producing adrenal adenomas who are judged to be poor operative risks or who decline surgery.

Long-term maintenance therapy for patients with bilateral micro- or macronodular adrenal hyperplasia (idiopathic hyperaldosteronism).

Edematous conditions for patients with:

Congestive heart failure

For the management of edema and sodium retention when the patient is only partially responsive to, or is intolerant of, other therapeutic measures. Aldactone is also indicated for patients with congestive heart failure taking digitalis when other therapies are considered inappropriate.

Cirrhosis of the liver accompanied by edema and/or ascites

Aldosterone levels may be exceptionally high in this condition. Aldactone is indicated for maintenance therapy together with bed rest and the restriction of fluid and sodium.

The nephrotic syndrome

For nephrotic patients when treatment of the underlying disease, restriction of fluid and sodium intake, and the use of other diuretics do not provide an adequate response.

Essential hypertension

Usually in combination with other drugs, Aldactone is indicated for patients who cannot be treated adequately with other agents or for whom other agents are considered inappropriate.


For the treatment of patients with hypokalemia when other measures are considered inappropriate or inadequate. Aldactone is also indicated for the prophylaxis of hypokalemia in patients taking digitalis when other measures are considered inadequate or inappropriate.

Usage in Pregnancy

The routine use of diuretics in an otherwise healthy woman is inappropriate and exposes mother and fetus to unnecessary hazard. Diuretics do not prevent development of toxemia of pregnancy, and there is no satisfactory evidence that they are useful in the treatment of developing toxemia.

Edema during pregnancy may arise from pathologic causes or from the physiologic and mechanical consequences of pregnancy.

Aldactone is indicated in pregnancy when edema is due to pathologic causes just as it is in the absence of pregnancy (however, see Precautions: Pregnancy ). Dependent edema in pregnancy, resulting from restriction of venous return by the expanded uterus, is properly treated through elevation of the lower extremities and use of support hose; use of diuretics to lower intravascular volume in this case is unsupported and unnecessary. There is hypervolemia during normal pregnancy which is not harmful to either the fetus or the mother (in the absence of cardiovascular disease), but which is associated with edema, including generalized edema, in the majority of pregnant women. If this edema produces discomfort, increased recumbency will often provide relief. In rare instances, this edema may cause extreme discomfort which is not relieved by rest. In these cases, a short course of diuretics may provide relief and may be appropriate.

CONCLUSIONS: Spironolactone stabilizes functional capacity and symptoms and

Spironolactone to prevent cardiovascular events in early-stage chronic kidney disease (STOP-CKD): study protocol for a randomized controlled pilot trial. [2014]
BACKGROUND: Chronic kidney disease is associated with increased arterial stiffness even in the early stages and this is thought to be a key mediator in the pathophysiology of the increased cardiovascular risk associated with this condition. The use of low-dose spironolactone has previously been shown to improve arterial stiffness and reduce left ventricular mass safely in early-stage chronic kidney disease in the context of careful monitoring at a university hospital...

Rationale and design of the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist Trial: A randomized, controlled study of spironolactone in patients with symptomatic heart failure and preserved ejection fraction. [2011.12]
BACKGROUND: Despite increasing prevalence of heart failure (HF) in patients with preserved ejection fraction (PEF), there are no available therapies proven to reduce morbidity and mortality. Aldosterone, a potent stimulator of myocardial and vascular fibrosis, may be a key mediator of HF progression in this population and is therefore an important therapeutic target. OBJECTIVE: The TOPCAT trial is designed to evaluate the effect of spironolactone, an aldosterone antagonist, on morbidity, mortality, and quality of life in patients with HF-PEF... CONCLUSION: TOPCAT is designed to assess definitively the role of spironolactone in the management of HF-PEF. Copyright (c) 2011 Mosby, Inc. All rights reserved.

Clinical Trials Related to Aldactone (Spironolactone)

High-Dose Aldactone for Treatment of Diuretic Resistant Heart Failure [Recruiting]
Prospective, open-label, randomized cohort study comparing adding high-dose spironolactone to usual heart failure care versus usual care in patients with acute decompensated heart failure. Patients will be randomized in a 1: 1 fashion to either usual care or high-dose spironolactone plus usual care. Both arms of the study will continue with treatment of ADHF until euvolemia as defined as the resolution of pulmonary edema, peripheral edema, abdominal bloating and/or jugular venous distention. Assessment of clinical status and serum electrolytes, symptoms and renal function will be performed in accordance to standard of care.

Acetazolamide and Spironolactone to Increase Natriuresis in Congestive Heart Failure [Recruiting]
This study has two primary objectives: 1. To compare combination therapy with acetazolamide and low-dose loop diuretics versus high-dose loop diuretics (standard of care) in patients with acute decompensated heart failure at high risk for diuretic resistance. 2. To demonstrate the safety and efficacy of upfront therapy with spironolactone in addition to loop diuretic therapy in patients with acute decompensated heart failure at high risk for diuretic resistance.

Effects of Spironolactone on Collagen Metabolism in Patients With Pulmonary Arterial Hypertension [Recruiting]
The purpose of this study is to determine the effects of spironolactone on collagen markers in a large number of patients with pulmonary hypertension. In addition, safety and tolerability of spironolactone, an aldosterone receptor antagonist, in patients with pulmonary arterial hypertension, will be determined.

Short Term Spironolactone for Prevention of Acute Kidney Injury After Cardiac Surgery [Recruiting]
Our aim is to test whether short term perioperative administration of oral spironolactone could reduce incidence of postoperative acute kidney injury (AKI) in cardiac surgical patients.

The Combination Ambrisentan Plus Spironolactone in Pulmonary Arterial Hypertension Study [Not yet recruiting]
The purpose of this study is to find out if spironolactone added to ambrisentan for Pulmonary Arterial Hypertension (PAH) will increase exercise capacity. We also want to find out if spironolactone and ambrisentan effect the cardiac output (amount of blood the heart pumps every minute), right ventricle function and quality of life.

Aldactone review by 62 year old female patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   No Side Effects
Treatment Info
Condition / reason:   swollen knee
Dosage & duration:   50mg taken 2x per day for the period of 2 yrs
Other conditions:   none
Other drugs taken:   vitamin supplements
Reported Results
Comments:   after two shots of cortisone to my knee, I had an mri done...this showed no problems yet the cortisone injections lasted only about four months. My dr did not want to give additional injections and prescribed physical therapy, which I did, but it only aleviated the pain for a short time and never for an entire day. My job requires me to be on my feet and I needed more relief. I went to an internist (the first doctor was a bone and joint specialist) who prescribed spiralactone. OK, I didnt have much faith in a water pill, but it worked and still continues to work. I do not take many medications but I do make sure I never run out of this miracle.
