Spironolactone Aldactone INDIA

Spironolactone, sold under the brand name Aldactone, is a potassium-sparing diuretic and aldosterone antagonist. It is used to manage conditions like hypertension, heart failure, edema, and hormone-related disorders. Spironolactone’s ability to block androgen receptors also makes it an essential therapy for conditions like acne, hirsutism, and as part of feminizing hormone therapy in transgender women.

Meccanismo d'azione
Spironolactone primarily functions by competitively inhibiting aldosterone at mineralocorticoid receptors in the kidneys. This reduces sodium reabsorption while conserving potassium, leading to a mild diuretic effect. Additionally, its anti-androgenic properties result from its ability to block androgen receptors and inhibit the enzyme 5-alpha reductase.

Indicazioni

Spironolactone Aldactone is widely used in managing:

1. Ipertensione: Particularly effective in resistant hypertension.
2. Edema: Associated with conditions like heart failure, cirrhosis, and nephrotic syndrome.
3. Heart Failure: Reduces morbidity and mortality in patients with systolic heart failure.
4. Hyperaldosteronism: Both primary and secondary forms.
5. Acne and Hirsutism: Off-label use for hormone-related skin conditions.
6. Gender-Affirming Hormone Therapy: For its androgen-blocking effects in transgender women.

Dosaggio e somministrazione

Dosages of Spironolactone Aldactone vary based on the condition being treated:

• Ipertensione: 25–100 mg daily, divided into one or two doses.
• Heart Failure: 25–50 mg daily.
• Acne or Hirsutism: 50–200 mg daily, depending on severity and response.
• Gender-Affirming Therapy: Often 100–200 mg daily, titrated based on clinical response and bloodwork.

Administration
Spironolactone is typically taken orally with food to improve absorption. Regular monitoring of electrolytes, especially potassium, is crucial.

Effetti collaterali

Common side effects include:

• Hyperkalemia (elevated potassium levels)
• Dizziness or fatigue
• Nausea e vomito
• Gynecomastia (breast enlargement)

Less common but serious side effects:

• Severe hyperkalemia leading to cardiac complications
• Endocrine changes, including menstrual irregularities
• Risk of metabolic acidosis in renal impairment

Precauzioni

Spironolactone Aldactone is contraindicated in:

• Severe kidney disease or anuria
• Addison’s disease
• Hyperkalemia or individuals using potassium supplements

Patients should avoid high-potassium diets and certain medications, such as ACE inhibitors, without medical supervision.

Riduzione del danno

1. Regular Monitoring: Frequent blood tests for potassium and renal function are critical to avoid complications like hyperkalemia.
2. Dietary Caution: Limit potassium-rich foods (e.g., bananas, spinach).
3. Avoid Overuse: Stick to prescribed dosages to prevent diuretic-related dehydration or imbalances.
4. Report Symptoms Promptly: Any signs of palpitations, muscle weakness, or severe fatigue may indicate electrolyte issues.

Spironolactone Aldactone is a cornerstone treatment for multiple conditions due to its versatility and efficacy. Adherence to medical guidance ensures its benefits outweigh any potential risks.
