ALDACTONE has been shown to be a tumorigen in chronic toxicity studies in rats . ALDACTONE should be used only in those conditions described under Indications and Usage. Unnecessary use of this drug should be avoided. Spironolactone is practically insoluble in water, soluble in alcohol, and freely soluble in benzene and in chloroform. Inactive ingredients include calcium sulfate, corn starch, flavor, hypromellose, iron oxide, magnesium stearate, polyethylene glycol, povidone, and titanium dioxide. ALDACTONE is a specific pharmacologic antagonist of aldosterone, acting primarily through competitive binding of receptors at the aldosterone-dependent sodium-potassium exchange site in the distal convoluted renal tubule. ALDACTONE causes increased amounts of sodium and water to be excreted, while potassium is retained. ALDACTONE acts both as a diuretic and as an antihypertensive drug by this mechanism. It may be given alone or with other diuretic agents that act more proximally in the renal tubule. Increased levels of the mineralocorticoid, aldosterone, are present in primary and secondary hyperaldosteronism. Edematous states in which secondary aldosteronism is usually involved include congestive heart failure, hepatic cirrhosis, and nephrotic syndrome. By competing with aldosterone for receptor sites, ALDACTONE provides effective therapy for the edema and ascites in those conditions. ALDACTONE counteracts secondary aldosteronism induced by the volume depletion and associated sodium loss caused by active diuretic therapy. ALDACTONE is effective in lowering the systolic and diastolic blood pressure in patients with primary hyperaldosteronism. It is also effective in most cases of essential hypertension, despite the fact that aldosterone secretion may be within normal limits in benign essential hypertension. Through its action in antagonizing the effect of aldosterone, ALDACTONE inhibits the exchange of sodium for potassium in the distal renal tubule and helps to prevent potassium loss. ALDACTONE has not been demonstrated to elevate serum uric acid, to precipitate gout, or to alter carbohydrate metabolism. ALDACTONE is rapidly and extensively metabolized. Sulfur-containing products are the predominant metabolites and are thought to be primarily responsible, together with ALDACTONE, for the therapeutic effects of the drug. The following pharmacokinetic data were obtained from 12 healthy volunteers following the administration of 100 mg of spironolactone daily for 15 days. On the 15th day, spironolactone was given immediately after a low-fat breakfast and blood was drawn thereafter. The pharmacological activity of spironolactone metabolites in man is not known. However, in the adrenalectomized rat the antimineralocorticoid activities of the metabolites C, TMS, and HTMS, relative to spironolactone were 1.10, 1.28, and 0.32, respectively. Relative to spironolactone, their binding affinities to the aldosterone receptors in rat kidney slices were 0.19, 0.86, and 0.06, respectively. Spironolactone and its metabolites are more than 90% bound to plasma proteins. The metabolites are excreted primarily in the urine and secondarily in bile. The effect of food on spironolactone absorption was assessed in a single-dose study of 9 healthy, drug-free volunteers. Food increased the bioavailability of unmetabolized spironolactone by almost 100%. The clinical importance of this finding is not known. Concomitant medications included a loop diuretic in 100% of patients and an ACE inhibitor in 97%. Other medications used at any time during the study included digoxin . The primary endpoint for RALES was time to all-cause mortality. RALES was terminated early, after a mean follow-up of 24 months, because of significant mortality benefit detected on a planned interim analysis. The survival curves by treatment group are shown in Figure 1. Figure 2: The size of each box is proportional to the sample size as well as the event rate. LVEF denotes left ventricular ejection fraction, Ser Creatinine denotes serum creatinine, Cr Clearance denotes creatinine clearance, and ACEI denotes angiotensin-converting enzyme inhibitor. 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 . 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. 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. 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. ALDACTONE is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program's Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure . Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension , and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal. Some antihypertensive drugs have smaller blood pressure effects . These considerations may guide selection of therapy. 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. To increase survival, and to reduce the need for hospitalization for heart failure when used in addition to standard therapy. 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 , 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 that is not relieved by rest. In these cases, a short course of diuretics may provide relief and may be appropriate. ALDACTONE is contraindicated for patients with anuria, acute renal insufficiency, significant impairment of renal excretory function, hyperkalemia, Addison's disease, and with concomitant use of eplerenone. Potassium supplementation, either in the form of medication or as a diet rich in potassium, should not ordinarily be given in association with ALDACTONE therapy. Excessive potassium intake may cause hyperkalemia in patients receiving ALDACTONE . ALDACTONE should not be administered concurrently with other potassium-sparing diuretics. ALDACTONE, when used with ACE inhibitors or indomethacin, even in the presence of a diuretic, has been associated with severe hyperkalemia. Extreme caution should be exercised when ALDACTONE is given concomitantly with these drugs. ALDACTONE should be used with caution in patients with impaired hepatic function because minor alterations of fluid and electrolyte balance may precipitate hepatic coma. Lithium generally should not be given with diuretics . All patients receiving diuretic therapy should be observed for evidence of fluid or electrolyte imbalance, e.g., hypomagnesemia, hyponatremia, hypochloremic alkalosis, and hyperkalemia. Serum and urine electrolyte determinations are particularly important when the patient is vomiting excessively or receiving parenteral fluids. Warning signs or symptoms of fluid and electrolyte imbalance, irrespective of cause, include dryness of the mouth, thirst, weakness, lethargy, drowsiness, restlessness, muscle pains or cramps, muscular fatigue, hypotension, oliguria, tachycardia, and gastrointestinal disturbances such as nausea and vomiting. Hyperkalemia may occur in patients with impaired renal function or excessive potassium intake and can cause cardiac irregularities, which may be fatal. Consequently, no potassium supplement should ordinarily be given with ALDACTONE. If hyperkalemia is suspected should be obtained. However, it is important to monitor serum potassium levels because mild hyperkalemia may not be associated with ECG changes. Reversible hyperchloremic metabolic acidosis, usually in association with hyperkalemia, has been reported to occur in some patients with decompensated hepatic cirrhosis, even in the presence of normal renal function. ALDACTONE therapy may cause a transient elevation of BUN, especially in patients with pre-existing renal impairment. ALDACTONE may cause mild acidosis. Somnolence and dizziness have been reported to occur in some patients. Caution is advised when driving or operating machinery until the response to initial treatment has been determined. Patients who receive ALDACTONE should be advised to avoid potassium supplements and foods containing high levels of potassium, including salt substitutes. Periodic determination of serum electrolytes to detect possible electrolyte imbalance should be done at appropriate intervals, particularly in the elderly and those with significant renal or hepatic impairments. Concomitant administration of ACE inhibitors with potassium-sparing diuretics has been associated with severe hyperkalemia. Concomitant administration may lead to severe hyperkalemia. Potentiation of orthostatic hypotension may occur. Intensified electrolyte depletion, particularly hypokalemia, may occur. ALDACTONE reduces the vascular responsiveness to norepinephrine. Therefore, caution should be exercised in the management of patients subjected to regional or general anesthesia while they are being treated with ALDACTONE. Possible increased responsiveness to the muscle relaxant may result. Lithium generally should not be given with diuretics. Diuretic agents reduce the renal clearance of lithium and add a high risk of lithium toxicity. In some patients, the administration of an NSAID can reduce the diuretic, natriuretic, and antihypertensive effect of loop, potassium-sparing, and thiazide diuretics. Combination of NSAIDs, e.g., indomethacin, with potassium-sparing diuretics has been associated with severe hyperkalemia. Therefore, when ALDACTONE and NSAIDs are used concomitantly, the patient should be observed closely to determine if the desired effect of the diuretic is obtained. ALDACTONE has been shown to increase the half-life of digoxin. This may result in increased serum digoxin levels and subsequent digitalis toxicity. It may be necessary to reduce the maintenance and digitalization doses when ALDACTONE is administered, and the patient should be carefully monitored to avoid over- or under-digitalization. Hyperkalemic metabolic acidosis has been reported in patients given ALDACTONE concurrently with cholestyramine. Several reports of possible interference with digoxin radioimmunoassay by ALDACTONE, or its metabolites, have appeared in the literature. Neither the extent nor the potential clinical significance of its interference has been fully established. A dose-related for a period of one year. In two-year studies in the rat, oral administration of potassium canrenoate was associated with myelocytic leukemia and hepatic, thyroid, testicular, and mammary tumors. Neither ALDACTONE nor potassium canrenoate produced mutagenic effects in tests using bacteria or yeast. In the absence of metabolic activation, neither ALDACTONE nor potassium canrenoate has been shown to be mutagenic in mammalian tests in vitro. In the presence of metabolic activation, ALDACTONE has been reported to be negative in some mammalian mutagenicity tests in vitro and inconclusive for mutagenicity in other mammalian tests in vitro. In the presence of metabolic activation, potassium canrenoate has been reported to test positive for mutagenicity in some mammalian tests in vitro, inconclusive in others, and negative in still others. Canrenone, a major metabolite of ALDACTONE, appears in human breast milk. Because ALDACTONE has been found to be tumorigenic in rats, a decision should be made whether to discontinue the drug, taking into account the importance of the drug to the mother. If use of the drug is deemed essential, an alternative method of infant feeding should be instituted. Safety and effectiveness in pediatric patients have not been established. The following adverse reactions have been reported and, within each category , are listed in order of decreasing severity. Digestive: Gastric bleeding, ulceration, gastritis, diarrhea and cramping, nausea, vomiting. Reproductive: Gynecomastia , inability to achieve or maintain erection, irregular menses or amenorrhea, postmenopausal bleeding, breast pain. Carcinoma of the breast has been reported in patients taking ALDACTONE but a cause and effect relationship has not been established. Hematologic: Leukopenia , thrombocytopenia. Hypersensitivity: Fever, urticaria, maculopapular or erythematous cutaneous eruptions, anaphylactic reactions, vasculitis. Metabolism: Hyperkalemia, electrolyte disturbances . Musculoskeletal: Leg cramps. Renal: Renal dysfunction . Skin: Stevens-Johnson Syndrome , alopecia, pruritis. Acute overdosage of ALDACTONE may be manifested by drowsiness, mental confusion, maculopapular or erythematous rash, nausea, vomiting, dizziness, or diarrhea. Rarely, instances of hyponatremia, hyperkalemia, or hepatic coma may occur in patients with severe liver disease, but these are unlikely due to acute overdosage. Hyperkalemia may occur, especially in patients with impaired renal function. Induce vomiting or evacuate the stomach by lavage. There is no specific antidote. Treatment is supportive to maintain hydration, electrolyte balance, and vital functions. ALDACTONE may be employed as an initial diagnostic measure to provide presumptive evidence of primary hyperaldosteronism while patients are on normal diets. ALDACTONE is administered at a daily dosage of 400 mg for three to four weeks. Correction of hypokalemia and of hypertension provides presumptive evidence for the diagnosis of primary hyperaldosteronism. ALDACTONE is administered at a daily dosage of 400 mg for four days. If serum potassium increases during ALDACTONE administration but drops when ALDACTONE is discontinued, a presumptive diagnosis of primary hyperaldosteronism should be considered. After the diagnosis of hyperaldosteronism has been established by more definitive testing procedures, ALDACTONE may be administered in doses of 100 to 400 mg daily in preparation for surgery. For patients who are considered unsuitable for surgery, ALDACTONE may be employed for long-term maintenance therapy at the lowest effective dosage determined for the individual patient. For adults, an initial daily dosage of 50 to 100 mg of ALDACTONE administered in either single or divided doses is recommended. ALDACTONE may also be given with diuretics that act more proximally in the renal tubule or with other antihypertensive agents. Treatment with ALDACTONE should be continued for at least two weeks since the maximum response may not occur before this time. Subsequently, dosage should be adjusted according to the response of the patient. ALDACTONE in a dosage ranging from 25 mg to 100 mg daily is useful in treating a diuretic-induced hypokalemia, when oral potassium supplements or other potassium-sparing regimens are considered inappropriate.. be taken. Large exposed wounds or sockets should be. Please wear comfortable clothing to the testing facility. You may have a light meal 3-4 hours before your test. You should not eat or drink again until after the test. It is important that you arrive on time for your Lexiscan Cardiolite Stress test. Due to the nature of the test does ambien stop working there are waiting times at different stages of the test. These are a normal part of the test protocol. Your dose and scanning materials will start being prepared when you sign in. You should plan to be in the office for 3-4 hours. 1. An IV will be placed in your arm. A small amount of radioisotope is injected through the IV. The amount of radiation you will be exposed to is similar to that of a chest X-ray. After a waiting period, a special camera takes pictures of your heart while you remain very still. 2. After the scan, Lexiscan will be injected through the IV. This medication is used to increase blood flow to your heart and will be injected over 10 seconds. A final injection of radioisotope will be injected about 25-30 seconds after the Lexiscan injection. 3.Following a waiting period, the camera will take a second set of pictures of your heart. These pictures will allow the physician to compare the amount of blood flowing through the heart muscle during stress and at rest. If you are diabetic and your test is scheduled before 12 noon, you should have a light breakfast and ½ of your morning insulin dose at least 3-4 hours before your appointment. For appointments after 12 noon, you may have a full breakfast with your entire morning dose of insulin. You may have a light snack 2-3 hours before your test. Fruit juice will be available if necessary. Please notify the nurse if you have asthma, bronchitis, or if you are currently taking Theo-dur or using inhalers. If you are actively wheezing, you may need to be changed to an alternate type of test, which will be decided by the MD after lung assessment. Do not smoke for 24 hours prior to the test. Do not consume caffeine 12 hours prior to the test. This includes coffee, cola, tea, chocolate, or any medications containing caffeine .
