Generic Eplerenone Information

Introduction

Eplerenone is a selective mineralocorticoid receptor antagonist used primarily to treat cardiovascular conditions such as hypertension and heart failure. In Hong Kong, it is prescribed by specialists to reduce morbidity and mortality associated with these disorders. The medication contains the active compound eplerenone and belongs to the general‑health drug group that targets hormonal regulation of fluid balance. In addition to its primary indications, eplerenone is sometimes employed off‑label for conditions where aldosterone excess contributes to disease progression.

What is Eplerenone?

Eplerenone is a synthetic, orally active steroid that blocks the mineralocorticoid receptor (MR) in the distal nephron and cardiovascular tissue. It was developed by Pfizer and introduced under the brand name Inspra in 2002.

Eplerenone is the generic version of Inspra, containing the same active compound eplerenone. Our online pharmacy provides this generic alternative as a cost‑effective treatment option. Generic eplerenone is formulated as film‑coated tablets containing the active ingredient and inert excipients that facilitate absorption and stability.

How Eplerenone Works

The mineralocorticoid receptor is a nuclear hormone receptor that mediates the effects of aldosterone, a hormone that promotes sodium reabsorption and potassium excretion in the kidneys. By competitively binding to the MR, eplerenone prevents aldosterone from activating the receptor. The result is:

• Reduced sodium and water retention, leading to lower blood volume and blood pressure.
• Decreased potassium loss, which helps maintain normal serum potassium levels.
• Attenuation of myocardial fibrosis and adverse remodeling, contributing to improved cardiac function in heart‑failure patients.

Eplerenone reaches peak plasma concentrations within 1.5–3 hours after oral administration. It is metabolised mainly by CYP3A4 to inactive metabolites and eliminated primarily via the kidneys (≈50 % unchanged). The half‑life ranges from 4 to 6 hours, supporting once‑daily dosing in most therapeutic regimens.

Conditions Treated with Eplerenone

• Hypertension – Particularly in patients whose blood pressure is not controlled by first‑line agents. By antagonising aldosterone, eplerenone provides an additive antihypertensive effect.
• Chronic Heart Failure (NYHA Class II–III) with reduced ejection fraction – Clinical trials (e.g., EMPHASIS‑HF) demonstrated a 30 % relative risk reduction in cardiovascular death or heart‑failure hospitalization when eplerenone was added to standard therapy.
• Post‑myocardial‑infarction left‑ventricular dysfunction – The EPHESUS trial showed improved survival in patients receiving eplerenone after acute MI with left‑ventricular ejection fraction ≤ 40 %.

In Hong Kong, cardiovascular disease remains the leading cause of death, accounting for over 30 % of all mortality (Hong Kong Hospital Authority, 2023). The availability of eplerenone therefore aligns with public‑health priorities to reduce heart‑failure burden and hypertension‑related complications.

Who is Eplerenone For?

Eplerenone is indicated for adult patients who meet any of the following criteria:

• Diagnosed with essential hypertension that requires an additional antihypertensive mechanism beyond renin‑angiotensin system blockade or calcium‑channel blockers.
• Have chronic systolic heart failure (left‑ventricular ejection fraction ≤ 40 %) and are already receiving an ACE inhibitor or angiotensin‑receptor blocker, a β‑blocker, and a diuretic.
• Experienced a myocardial infarction with left‑ventricular dysfunction and are stable on guideline‑directed therapy.

Suitable candidates often exhibit elevated plasma aldosterone or signs of fluid overload. Contra‑indications include:

• Serum potassium > 5. mmol/L or severe renal impairment (eGFR < 30 mL/min/1.73 m²).
• Known hypersensitivity to eplerenone or any tablet excipients.
• Concurrent use of potent CYP3A4 inhibitors (e.g., ketoconazole, itraconazole) unless dose adjustment and close monitoring are possible.

Patients with mild to moderate renal dysfunction, well‑controlled potassium, and no interacting medications are typical beneficiaries of eplerenone therapy.

Risks, Side Effects, and Interactions

Common

• Hyperkalaemia – Elevated serum potassium, usually mild and asymptomatic.
• Dizziness or light‑headedness – Related to blood‑pressure reduction, especially after the first dose.
• Headache – Transient and often resolves without intervention.

Rare

• Gynecomastia – Much less frequent than with non‑selective MR antagonists such as spironolactone.
• Rash or pruritus – Dermatologic reactions that may necessitate discontinuation if severe.

Serious

• Severe hyperkalaemia – Potassium > 6. mmol/L can cause cardiac arrhythmias; requires immediate medical attention.
• Acute renal failure – Particularly when combined with nephrotoxic agents or in patients with pre‑existing renal disease.
• Anaphylaxis – Rare IgE‑mediated hypersensitivity reaction; emergency care required.

Drug–Drug Interactions

• Potassium‑sparing diuretics (e.g., amiloride, triamterene) – Additive risk of hyperkalaemia.
• ACE inhibitors, ARBs, or direct renin inhibitors – Combined therapy increases potassium and may require dose adjustment.
• CYP3A4 inhibitors (e.g., azole antifungals, macrolide antibiotics, HIV protease inhibitors) – Increase eplerenone plasma concentrations; consider a 50 % dose reduction.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – May blunt antihypertensive effect and impair renal function.

Patients should disclose all prescription, over‑the‑counter, and herbal products to their healthcare provider before initiating eplerenone.

Practical Use: Dosing, Missed Dose, Overdose

• Initial dose for hypertension: 25 mg once daily; may be increased to 50 mg after 2–4 weeks if tolerated.
• Heart‑failure dose: Start with 25 mg once daily, titrating to 50 mg after 4 weeks; the maximum recommended dose is 50 mg daily.
• Renal impairment adjustment: For eGFR 30–50 mL/min/1.73 m², initiate at 25 mg and avoid exceeding 25 mg daily.
• Missed dose: Take the missed tablet as soon as remembered unless the next scheduled dose is within 12 hours; in that case, skip the missed dose and continue the regular regimen. Do not double the dose.
• Overdose: Symptoms may include severe hyperkalaemia, hypotension, and renal dysfunction. Immediate medical evaluation is essential. Activated charcoal is not useful; treatment focuses on electrolyte correction (e.g., insulin‑glucose infusion, calcium gluconate) and supportive care.

Food does not significantly affect absorption, but patients should avoid excessive potassium‑rich foods (bananas, oranges, tomatoes) while on therapy. Alcohol intake should be moderate, as excessive consumption can worsen blood‑pressure control and renal function.

FAQ

• Is eplerenone available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name product is marketed as Inspra, while generic versions containing the same active compound eplerenone are widely available through reputable distributors, including our online pharmacy.

• Does eplerenone require refrigeration or any special storage conditions?
  No. Eplerenone tablets should be stored at room temperature, protected from excessive heat, moisture, and direct sunlight. Keeping them in a dry place such as a cabinet is sufficient.

• What does the packaging of eplerenone look like when ordered online?
  The medication is supplied in sealed, tamper‑evident blister packs or bottles, each bearing the generic manufacturer’s label, batch number, and expiry date. Packaging complies with international pharmacy standards.

• Can eplerenone be imported for personal use without a local prescription in Hong Kong?
  Personal import of prescription‑only medicines is permitted under the Hong Kong Customs and Excise Department if the quantity does not exceed a 30‑day supply and the importer holds a valid prescription. Our service provides the medication to customers who already have a prescription from a qualified healthcare professional.

• Are there any specific warnings for Asian populations taking eplerenone?
  Clinical data do not indicate ethnicity‑specific dosing differences. However, Asian patients may have a higher prevalence of reduced renal function, so baseline kidney function and serum potassium should be evaluated before initiation.

• Do tablet colors or shapes differ between regions such as the United States, Europe, and Asia?
  Yes. Generic eplerenone tablets may vary in imprint, shape, and color depending on the manufacturer. In Hong Kong, common generic versions are round, white to off‑white tablets with the imprint “EPL” or the manufacturer’s logo.

• What is the recommended interval between taking eplerenone and a high‑potassium meal?
  There is no strict timing requirement, but patients should avoid consistently consuming very high‑potassium foods (e.g., > 1,000 mg potassium per meal) while on therapy. Regular monitoring of serum potassium helps guide dietary adjustments.

• How long does it typically take for eplerenone to lower blood pressure after the first dose?
  Blood‑pressure reduction may be observed within 1–2 weeks, with maximal effect usually reached after 4–6 weeks of consistent dosing, depending on individual response and concomitant antihypertensive agents.

• Is eplerenone detectable in standard workplace drug tests?
  No. Eplerenone is not a controlled substance and does not appear on routine employment drug‑screening panels, which target illicit drugs, narcotics, and certain prescription medications like opioids and benzodiazepines.

• Can eplerenone be taken with vitamin D or calcium supplements?
  Yes. Vitamin D and calcium do not interact with eplerenone’s metabolic pathway. However, patients should maintain adequate hydration and have periodic renal function checks when using supplements that affect calcium metabolism.

• What clinical trial established eplerenone’s benefit after myocardial infarction?
  The EPHESUS (Eplerenone Post‑Acute Myocardial Infarction Heart Failure Efficacy and Survival Study) trial enrolled over 6,600 patients and demonstrated a 15 % reduction in cardiovascular death and a 20 % reduction in heart‑failure hospitalization with eplerenone added to standard therapy.

• Does eplerenone have any effect on blood glucose levels?
  Current evidence shows no clinically significant impact on glycaemic control. Patients with diabetes should still monitor blood glucose regularly, as any antihypertensive regimen may indirectly affect metabolic parameters.
