What’s Inside & How It Works

Ingredients overview

Eplerenone film-coated tablets contain both active and inactive ingredients crucial for their functionality. The primary active ingredient is eplerenone itself, which is an aldosterone receptor antagonist used predominantly for treating hypertension and heart failure.

Inactive ingredients may include compounds such as lactose, magnesium stearate, and various film-coating agents, which aid in tablet stability and absorption. These components are carefully chosen to ensure efficacy while maximizing patient comfort.

Mechanism basics

How does eplerenone work? This medication inhibits aldosterone receptors, leading to reduced sodium and water retention, which helps lower blood pressure. As a potassium-sparing diuretic, it minimizes potassium loss compared to other diuretics.

In the cardiovascular system, eplerenone helps decrease myocardial fibrosis and improve ventricular function, particularly after a myocardial infarction. This dual action helps mitigate the risks associated with heart failure and supports overall heart health.

Main Indications

Approved uses in Canada

Health Canada has approved eplerenone for several critical conditions. It is primarily used to manage essential hypertension, helping to lower blood pressure in patients with risk factors for cardiovascular disease.

In addition, eplerenone is indicated for post-myocardial infarction heart failure patients with left ventricular ejection fraction (LVEF) less than or equal to 40%. This usage is essential for improving outcomes in patients recovering from significant cardiac events.

Off-label uses by Canadian physicians

Canadian healthcare professionals often utilize eplerenone off-label for various conditions. Common off-label uses include treatment for diabetic nephropathy and conditions associated with hyperaldosteronism. The antihypertensive effects and unique steroidal structure allow for diverse applications in clinical practice.

Interaction Warnings

Food interactions (alcohol, caffeine)

Certain foods and drinks can influence eplerenone's effectiveness. Alcohol consumption, for instance, can exacerbate the hypotensive effects of eplerenone, leading to increased dizziness or fainting. Caffeine may also interact, potentially causing fluctuations in blood pressure, though the exact mechanism is less defined.

Drug conflicts (Health Canada database)

Significant drug interactions also exist. Eplerenone may conflict with other medications that raise potassium levels, such as ACE inhibitors or certain non-steroidal anti-inflammatory drugs (NSAIDs). Health Canada’s database suggests close monitoring of potassium levels when these medications are used concurrently.

Latest Evidence & Insights
