Inospiron 25 mg is primarily indicated for conditions associated with fluid retention, hypertension, and potassium imbalance. Its main indications include:

1. Congestive Heart Failure (CHF):

   • Helps reduce edema and fluid overload in patients with heart failure.

2. Hepatic Cirrhosis with Ascites and Edema:

   • Assists in managing fluid accumulation in liver disease patients.

3. Nephrotic Syndrome:

   • Reduces swelling caused by kidney disorders.

4. Primary Hyperaldosteronism:

   • Used pre-operatively or as long-term therapy in patients with excess aldosterone production.

5. Essential Hypertension:

   • Lowers blood pressure by promoting sodium and water excretion while retaining potassium.

6. Hypokalemia (Low Potassium):

   • Corrects potassium deficiency caused by other diuretics.

Therapeutic Class

• Potassium-Sparing Diuretics

• Aldosterone Antagonists

Pharmacology / Mode of Action

Inospiron 25 mg is a selective aldosterone antagonist. It works by binding competitively to mineralocorticoid receptors in the distal convoluted renal tubule, which blocks the effects of aldosterone.

Mechanism:

• Sodium & Water Excretion: Prevents sodium reabsorption, promoting diuresis.

• Potassium Retention: Limits potassium excretion, helping maintain electrolyte balance.

• Blood Pressure Reduction: By reducing fluid volume and vascular resistance.

• May be used alone or in combination with other diuretics that act on more proximal parts of the nephron.

Dosage & Administration

Edema (CHF, cirrhosis, nephrotic syndrome):

• Initial: 100 mg daily (single or divided doses)

• Range: 25–200 mg daily

Primary Hyperaldosteronism:

• 100–400 mg daily, depending on pre- or post-surgery requirements

Essential Hypertension:

• 50–100 mg daily

Hypokalemia:

• 25–100 mg daily

Notes: Doses should be individualized based on patient response and condition.

Drug Interactions

• ACE Inhibitors: May increase risk of hyperkalemia

• Lithium: Risk of toxicity due to decreased renal clearance

• Digoxin: Can increase digoxin half-life

• Alcohol, Barbiturates, Narcotics: May potentiate orthostatic hypotension

• Corticosteroids, ACTH: Can worsen electrolyte imbalance

Contraindications

• Acute renal insufficiency or significant renal impairment

• Anuria

• Hyperkalemia

• Hypersensitivity to Inospiron 25 mg

Side Effects

• Endocrine: Gynecomastia, irregular menses, post-menopausal bleeding

• Gastrointestinal: Cramping, diarrhea

• Neurological: Drowsiness, lethargy, headache, mental confusion

• Others: Impotence, urticaria

Pregnancy & Lactation

• Pregnancy: Not recommended

• Lactation: Canrenone, an active metabolite, appears in breast milk; consider alternative feeding methods if necessary

Precautions & Warnings

• Monitor electrolytes, particularly potassium

• Risk of hyperkalemia in patients with impaired renal function or high potassium intake

• Watch for signs of fluid imbalance

Overdose Effects

• Symptoms: Drowsiness, dizziness, mental confusion, diarrhea, vomiting

• Management: Gastric lavage, supportive treatment, monitoring electrolytes

Storage

• Store in a cool, dry place, protected from light

• Keep out of reach of children.
