In EMPHASIS-HF, eplerenone improved outcomes in HFrEF patients with and without abdominal obesity, although the benefit appeared to be more pronounced among those with abdominal obesity. Compared with healthy subjects matched according to age, weight and gender, steady state AUC and Cmax in heart failure patients were 38% and 30% higher, respectively. the workload on the heart can contribute towards improving the efficiency of cardiac function in individuals with heart failure. JACC Basic Transl. Avoid or Use Alternate Drug. Mechanism of action. Myocardial fibrosis Elevated aldosterone levels have been associated with increased mortality. Spironolactone: taken orally with doses of 12.5-25 mg per day and has a long half-life of 13-17 hours. Potassium-Sparing Diuretics and Mechanism of Action. drospirenone. Furthermore, the hospitalisation rate and costs of care are enormous. Spironolactone is FDA approved for the treatment of heart failure with reduced ejection fraction (HFrEF), resistant hypertension, primary hyperaldosteronism, edema secondary to cirrhosis, edema secondary to a nephrotic syndrome that is not adequately controlled using alternative therapies, and hypokalemia. The pharmacokinetics of eplerenone 50 mg was evaluated in 8 patients with heart failure (NYHA classification II-IV) and 8 matched (gender, age, weight) healthy controls. Heart failure is a not a specific disease per se but rather a clinical syndrome caused by numerous different cardiac disorders. 2.4 Dose Modifications for Use with Moderate CYP3A inhibitors 12.1 Mechanism of Action . It is in the mineralocorticoid receptor antagonist class of drugs. To elucidate the beneficial cardioprotective mechanism of eplerenone, a novel selective aldosterone blocker, we hypothesized that eplerenone stimulates endothelial NO synthase (eNOS) through Akt and inhibits inducible NO synthase (iNOS) via nuclear factor κB (NF-κB) after the development of oxidative stress and . The clinical utility of MRA in stable patients with heart failure and reduced LVEF was first demonstrated in the Randomized Aldactone Evaluation Study (RALES) in 1991. Diuretic Management in Heart Failure H eart failure is a major public health burden in the developed world and is associated with high . . Compared with the controls, steady state AUC and Cmax in patients with stable heart failure were 38% and 30% higher, respectively. Eplerenone is a new selective aldosterone receptor antagonist that has been recently approved for use in patients with left ventricular systolic dysfunction and clinical evidence of heart failure. Eplerenone, the selective mineralocorticoid receptor antagonist, is a promising cardiovascular drug licensed for the treatment of heart failure in Europe and heart failure and hypertension in the USA. Compared with the controls, steady state AUC and C max in patients with stable heart failure were 38% and 30% higher, respectively. 4, 831-840 . It can sometimes be used to treat a condition called hyperaldosteronism. By blocking aldosterone, eplerenone helps prevent . Prototype: Furosemide (Lasix) Mechanism of Action Blocks reabsorption of sodium and chloride in the descending limb of Henle's loop to promote urination Produces profound diuresis Uses Rapid mobilization of fluid Pulmonary edema resulting from heart failure or renal or liver disease Especially useful in patients with renal insufficiency Adverse Effects Hyponatremia, hypochloremia . Therapy with an aldosterone antagonist (i.e., eplerenone or spironolactone) recommended by ACCF and AHA to reduce morbidity and mortality following acute MI in patients with reduced LVEF (≤40%) who develop symptoms of heart failure or who have a history of diabetes mellitus, unless contraindicated. The RALES and EPHESUS trials have provided data demonstrating survival benefits with spironolactone and eplerenone in chronic and postinfarction heart failure, leading to more frequent and . The pharmacokinetics of eplerenone 50 mg were evaluated in patients with heart failure (NYHA classification II-IV). 2, 3 Pharmacologic therapy is a major component in the management of heart failure and can include angiotensin-converting-enzyme (ACE . These drugs are contraindicated in situations in which hyperkalemia occurs as well as patients predisposed to hyperkalemia. Eplerenone is a selective mineralocorticoid-receptor antagonist. HF is the most common cause of hospitalisation in patients over the age of 65 . The major trials of ARAs in heart failure to date have been the Randomized Aldactone Evaluation Study (RALES), the Eplerenone Post-acute Myocardial Infarc-tion Heart Failure Efficacy and Survival Study (EPHESUS), and the Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure (EMPHASIS-HF). Eplerenone is also used to treat high blood pressure (hypertension). Iborra-Egea, O. et al. Eplerenone (Inspra) and spironolactone (Aldactone) are both aldosterone antagonists that can be used for the treatment of hypertension (HTN) and heart failure (HF) due to left ventricular systolic dysfunction.1,2 In addition to these indications, spironolactone is also used in the management of primary hyperaldosteronism, edema from cirrhosis, and prophylaxis against hypokalemia.2 Additionally . Eplerenone has been shown to produce sustained increases in plasma renin and serum aldosterone . Therefore, patients hospitalized for heart failure, those in a fluid-overload state and those who are symptomatically hypotensive should not be given carvedilol. 1 Although treatment strategies have improved morbidity and mortality rates over the past 20 years, the 5-year mortality rate is approximately 50%. 2.3 Recommended Monitoring. Eplerenone is a medication used in the management and treatment of heart failure with reduced ejection fraction and hypertension. Eplerenone is prescribed alongside other medicines to help prevent worsening of heart failure in people who have left-sided heart failure.
