## Introduction

Aldactone is a generic oral medication whose active ingredient is spironolactone. It is supplied as a pill in strengths of 25 mg and 100 mg and belongs to the class of potassium-sparing diuretics. The drug is primarily prescribed to lower blood pressure, reduce fluid retention, and treat conditions caused by excess aldosterone. It is also used in certain hormonal disorders such as primary hyperaldosteronism.

## Quick Reference Facts

**Active Ingredient** 
: spironolactone 

**Form** 
: pill - 25 mg | 100 mg 

**Primary Uses** 
: hypertension, congestive heart failure, edema, primary hyperaldosteronism 

## What is Aldactone?

Aldactone is the generic version of medications containing the active compound spironolactone. It is classified as a potassium-sparing diuretic and an aldosterone antagonist. The drug was first developed in the early 196s and is now marketed worldwide by many manufacturers. While the brand name Aldactone is widely recognised, the generic formulation is bioequivalent to the branded product and is listed among the therapeutic alternatives for the same indications. Common brand equivalents include CaroSpir, Loara, and other regional trademarks.

## How Aldactone Works

Spironolactone blocks the mineralocorticoid receptor, preventing aldosterone from binding to cells in the distal nephron of the kidney. Aldosterone normally promotes sodium reabsorption and potassium excretion; by inhibiting this pathway, aldosterone antagonism leads to modest diuresis while conserving potassium. The net effect is a reduction in extracellular fluid volume, which lowers blood pressure and relieves edema. Spironolactone is metabolised in the liver to several active metabolites, most notably canrenone, which retains aldosterone-blocking activity. The drug’s onset of action is typically observed within 2-3 days, and steady-state concentrations are reached after about 10 days of consistent dosing.

## Conditions Treated with Aldactone

- **Hypertension** - By decreasing sodium retention and vascular volume, spironolactone helps lower systemic blood pressure, especially in resistant cases.
- **Congestive Heart Failure** - The medication reduces preload and afterload, improving symptoms and decreasing hospitalization risk.
- **Edema (including hepatic cirrhosis-related ascites)** - Fluid accumulation is mitigated through enhanced urinary excretion without causing significant potassium loss.
- **Primary Hyperaldosteronism (Conn’s syndrome)** - Direct antagonism of excess aldosterone corrects electrolyte imbalances and hypertension.
- **Nephrotic Syndrome-related edema** - Provides additional diuretic effect when combined with loop diuretics.

## Is Aldactone the Right Medication for You?

Aldactone is appropriate for adults who require an aldosterone antagonist to manage fluid overload, high blood pressure, or hormonal excess. It is especially useful when:

- Blood pressure remains uncontrolled despite standard antihypertensives.
- Heart failure patients need adjunctive therapy to reduce hospital admissions.
- Patients with primary hyperaldosteronism have confirmed diagnostic testing.

**Contraindications** include:

- Known hypersensitivity to spironolactone or any of its excipients.
- Severe renal impairment (eGFR < 30 mL/min/1.73 m²) because clearance is reduced.
- Hyperkalemia (serum potassium > 5. mmol/L) or conditions predisposing to high potassium.
- Addison’s disease or other conditions of endogenous mineralocorticoid deficiency.

Physicians typically avoid Aldactone in pregnant women, nursing mothers, and individuals with significant hepatic dysfunction unless benefits outweigh risks.

## Use: Dosing, Missed Dose, Overdose

- **Standard Dosing** - For hypertension, the usual starting dose is 25 mg once daily, titrated up to 100 mg as needed. In heart failure, 25 mg once daily is common, with adjustments based on renal function and potassium levels.
- **Missed Dose** - Take the missed tablet as soon as you remember, unless the next scheduled dose is within a few hours. In that case, skip the missed dose and resume the regular schedule. Do not double-dose.
- **Overdose** - Symptoms may include nausea, vomiting, severe dizziness, and hyperkalemia. Seek emergency medical care immediately. Activated charcoal may be administered if presentation is early.
- **Administration Tips** - Aldactone can be taken with or without food. Avoid high-potassium foods (e.g., bananas, oranges, potatoes) and potassium-containing supplements while on therapy. Caution is advised when operating machinery until you know how the medication affects you.

## Safety Information

### ⚠️ Who Should Not Take Aldactone

- Individuals with serum potassium > 5. mmol/L.
- Patients with severe renal impairment (eGFR < 30 mL/min/1.73 m²).
- Those with known hypersensitivity to spironolactone or its excipients.
- Patients with Addison’s disease or other mineralocorticoid deficiencies.
- Pregnant or breastfeeding women, unless directed by a physician.

### Common Side Effects

- **Gynecomastia** (male breast enlargement) - occurs in ≤ 10 % of men, often reversible upon discontinuation.
- **Menstrual irregularities** - spotting or amenorrhea in women.
- **Hyperkalemia** - mild elevations in serum potassium are the most frequently monitored laboratory change.
- **Dizziness or headache** - generally mild and transient.

### Serious Side Effects (Seek Immediate Medical Help)

- **Severe hyperkalemia** - muscle weakness, arrhythmias, or cardiac arrest.
- **Anaphylactic reaction** - rash, itching, swelling, severe breathing difficulty.
- **Significant liver dysfunction** - jaundice, dark urine, persistent abdominal pain.

If any of these occur, contact emergency services without delay.

### Drug & Food Interactions

- **ACE inhibitors & ARBs** - combined use increases the risk of hyperkalemia; potassium levels should be closely monitored.
- **Potassium supplements or salt substitutes** - may precipitate dangerous potassium elevations.
- **NSAIDs** - can decrease renal clearance of spironolactone, heightening the risk of renal impairment.
- **Thiazide diuretics** - may counteract potassium-sparing effect, requiring dose adjustments.
- **Certain antibiotics (e.g., trimethoprim-sulfamethoxazole)** - can impair potassium excretion.
