Generic Aldactone Information

Introduction

Aldactone is a medication containing the active compound spironolactone. It belongs to the diuretic class of drugs and is used primarily for conditions that involve fluid overload and hypertension. Within the United Kingdom, Aldactone is prescribed for the management of high blood pressure, secondary hyper‑aldosteronism, and certain forms of oedema. It also has recognised secondary uses such as treatment of resistant hypertension and mitigation of protein‑urine loss in chronic kidney disease. The drug is produced by several manufacturers; one widely known brand of spironolactone is Aldactone (Pfizer), while other licences market the same compound under names such as Corgard or Spiro‑Norm.

What is Aldactone?

Aldactone is a oral diuretic formulation that contains spironolactone as its sole active ingredient. Spir​onolactone is a synthetic potassium‑sparing thiazide‑like diuretic that was first synthesised in the 195s and introduced into clinical practice in the early 196s. In the UK, Aldactone is marketed by licensed pharmaceutical companies that hold a UK Medicines Licence issued by the Medicines and Healthcare products Regulatory Agency (MHRA). The product is supplied in film‑coated tablets of 25 mg, 50 mg, and 100 mg strengths.

Aldactone is the generic version of the original branded spironolactone product known as Aldactone (Pfizer), containing the same active compound Spironolactone. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Aldactone Works

Spironolactone acts as a competitive antagonist of the mineralocorticoid receptor (also called the aldosterone receptor) located in the distal tubules and collecting ducts of the kidney. By blocking aldosterone, it reduces sodium reabsorption and promotes sodium excretion while conserving potassium. The net effect is a reduction of extracellular fluid volume, lowering blood‑pressure‑raising wall tension, and decreasing oedema formation.

Because spironolactone also interferes with renal and vascular fibroblast activity, it can blunt the maladaptive effects of excess aldosterone on cardiac and vascular remodeling. The drug has an oral absorption of approximately 90 % and reaches peak plasma concentrations within 2–3 hours after ingestion. It is metabolised in the liver to several active metabolites (notably canrenone) which contribute to its clinical effect. Elimination half‑life for the parent compound is roughly 1.4 hours, while the active metabolite’s half‑life extends to 16–18 hours, giving a prolonged pharmacodynamic profile that supports once‑daily dosing in most regimens.

Conditions Treated with Aldactone

• Primary and secondary hypertension – Aldactone reduces blood pressure by antagonising aldosterone‑mediated sodium retention, a mechanism that complements ACE‑inhibitors or calcium‑channel blockers (NICE guideline NG136, 2022).
• Heart failure with reduced ejection fraction (HFrEF) – In combination with ACE‑inhibitors or ARBs, spironolactone improves survival and reduces hospitalisation; the benefit is linked to aldosterone blockade (RALES trial, 1999).
• Edema secondary to liver cirrhosis (ascites) – By promoting free water excretion without hypokalaemia, Aldactone helps control refractory ascites (UK consensus, 2021).
• Primary hyperaldosteronism (Conn’s syndrome) – As an antagonist, it reduces the clinical impact of excess aldosterone while definitive treatment (surgery or adrenal‑sparing therapy) is arranged.
• Polycystic ovary syndrome (PCOS) – off‑label – Aldactone may counteract hyper‑androgenism caused by excess aldosterone, though this use is not routinely authorised in the UK.

Epidemiologically, hypertension affects approximately 30 % of adults in England, Wales, and Scotland, making aldosterone‑targeting therapies a significant component of national disease‑management pathways (Public Health England, 2023).

Suitable Candidates for Aldactone Treatment

Patients who present with one or more of the following features are most likely to benefit from Aldactone:

• Resistant or high‑renin hypertension – when conventional agents fail to achieve target ≤ 140/90 mmHg.
• Documented hyperaldosteronism – via biochemical testing or imaging evidence of adrenal adenoma.
• Concomitant potassium‑sparing requirement – cases where hypokalaemia must be avoided, such as in patients on ACE‑inhibitors/ARBs.
• Mild to moderate renal impairment (eGFR ≥ 30 mL/min/1.73 m²) – where aldosterone blockade can slow proteinuria progression.

Contra‑indications or caution include: severe renal failure (eGFR < 30), hyperkalaemia (K⁺ > 5.5 mmol/L), pregnancy, lactation, and known hypersensitivity to spironolactone or its excipients.

Risks, Side Effects, and Interactions

Common adverse events

• Hyperkalaemia – elevation of serum potassium, especially when combined with ACE‑inhibitors, ARBs, or potassium supplements.
• Gynephobic side effects – menstrual irregularities, breast tenderness, or decreased libido (observed in ≤ 5 % of users).
• Gastrointestinal upset – nausea, abdominal discomfort, or diarrhoea.

Rare adverse events

• Endocrine disturbances – gynecomastia in males (≈ 1 %), menorrhagia in females.
• Skin reactions – rash, pruritus, or urticaria.
• Metabolic effects – mild increase in serum creatinine or uric acid levels.

Serious adverse events

• Life‑threatening hyperkalaemia – may precipitate ventricular arrhythmia or cardiac arrest, especially in patients with renal dysfunction.
• Severe hypersensitivity reactions – anaphylaxis, angioedema, or Stevens‑Johnson‑like skin eruption (extremely rare).
• Hepatic dysfunction – marked transaminase elevation (> 5 × ULN) reported in isolated case series.

Interactions

• Potassium‑increasing agents – co‑administration with ACE‑inhibitors, ARBs, β‑blockers, or potassium supplements raises hyperkalaemia risk; regular monitoring of electrolytes is advised (NHS guidance, 2022).
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – may attenuate the natriuretic effect and increase renal adverse events.
• Renin‑angiotensin system blockers – synergistic blood‑pressure reduction, but careful dose titration is required.
• Lithium – spironolactone reduces renal clearance of lithium, potentially causing lithium toxicity.

Patients should avoid high‑potassium foods (e.g., bananas, oranges, potassium‑rich vegetables) while on Aldactone unless otherwise directed by a clinician.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing – For hypertension, initial adult dose is 25 mg once daily; titration to 50 mg or 100 mg may follow after 2–4 weeks based on response and tolerability. For heart failure, a typical start is 25 mg with gradual increase to 50 mg daily (BNF, 2023).
• Missed dose – Take the missed tablet as soon as remembered unless it is close to the next scheduled dose; in that case, skip the missed dose and continue with the regular schedule. Do not double the dose.
• Overdose – Acute ingestion of > 200 mg is considered potentially toxic. Immediate medical assistance is required; treatment focuses on correcting hyperkalaemia (calcium gluconate, insulin‑glucose, β‑blockers) and supportive monitoring.

Precautions – Aldactone should be taken with food or a light snack to minimise gastrointestinal irritation. Alcohol can potentiate blood‑pressure‑lowering effects and should be limited. Patients with diabetes, gout, or liver disease should discuss specific monitoring requirements with their clinician.

FAQ

• Is Aldactone available in both brand‑name and generic forms in the UK?
  Yes. The original branded product, marketed as Aldactone by Pfizer, contains spironolactone. Generic versions are produced by several suppliers and contain the identical active ingredient, offering a lower price point.

• What are the typical appearance and imprint of Aldactone tablets?
  Aldactone tablets are film‑coated, white to off‑white round discs. The 25 mg strength bears the imprint “A25,” the 50 mg “A50,” and the 100 mg “A100,” although imprints may vary between manufacturers.

• How should Aldactone be stored to maintain its stability?
  Store the tablets at a temperature between 15 °C and 30 °C, protected from direct light, moisture, and humidity. Do not keep the medication in a bathroom cabinet or near a kitchen sink where steam may degrade the tablet coating.

• Can Aldactone be taken while travelling internationally?
  Yes, but you should keep the medication in its original packaging, carry a copy of the prescription, and be aware of the destination country’s rules on personal import of medicines. In the EU and many Commonwealth nations, a three‑month supply for personal use is generally permissible.

• Does Aldactone have any known formulation differences across regions?
  The active ingredient is identical worldwide, but excipients such as lactose, corn starch, or magnesium stearate can vary. Patients with specific allergies should verify the full ingredient list supplied by the pharmacy before purchase.

• Are there specific warnings for Aldactone in patients of Asian ethnicity?
  Some studies have indicated that Asian patients may experience higher rates of hyperkalaemia at equivalent doses, possibly due to genetic variations in renal handling of potassium. Dose adjustment and close electrolyte monitoring are recommended in this population.

• What are the legal requirements for importing Aldactone for personal use in the UK?
  The Medicines and Healthcare products Regulatory Agency permits the import of a three‑month personal supply for a private individual, provided it is for personal use, not for resale, and the product is accompanied by a valid prescription.

• Can Aldactone interfere with drug screening for employment?
  Standard workplace drug tests do not detect spironolactone, as it is not a narcotic or controlled substance. However, its metabolites may appear in a comprehensive toxicology screen, though this is uncommon.

• How does Aldactone compare to older potassium‑sparing diuretics such as amiloride?
  While both spare potassium, spironolactone uniquely blocks aldosterone receptors, conferring additional blood‑pressure‑lowering and anti‑fibrotic benefits. Amiloride acts on the distal tubule’s ENaC channel and lacks the anti‑aldosterone effect, making Aldactone the preferred choice for conditions driven by excess aldosterone.

• What is the shelf‑life of Aldactone tablets after shipment?
  Manufacturer‑specified expiry is typically 24 months from the date of manufacturing. The pharmacy will display the expiry date on each pack; patients should avoid using tablets beyond this date.
