Indapamida Krka (Indapamide)

Indapamide is a thiazide‑like diuretic used to manage conditions related to fluid overload and elevated blood pressure.

• Hypertension: lowers systemic blood pressure and reduces cardiovascular risk.
• Edema associated with heart failure: promotes fluid excretion to relieve swelling.
• Edema associated with renal disease: enhances diuresis to decrease peripheral edema.

• Indapamide inhibits sodium‑chloride reabsorption in the distal convoluted tubule by blocking the Na+/Cl‑ cotransporter, leading to increased urinary excretion of sodium and water. The resulting reduction in plasma volume lowers peripheral vascular resistance, contributing to its antihypertensive effect while also decreasing fluid accumulation in edematous states.

Indapamide may cause a range of adverse reactions, from mild to serious.

Common Side Effects

• Increased urination: more frequent need to void.
• Electrolyte imbalance (low potassium): may cause muscle weakness.
• Dizziness or light‑headedness: especially on standing.
• Headache: mild to moderate intensity.
• Fatigue: general feeling of tiredness.
• Elevated blood glucose: may affect diabetic control.

Serious or Rare Side Effects

• Severe dehydration: risk of hypotension and renal impairment.
• Significant electrolyte disturbances (hypokalemia, hyponatremia): can lead to cardiac arrhythmias.
• Gout attacks: increased uric acid levels.
• Allergic reactions: rash, itching, or angioedema.
• Blood dyscrasias: rare cases of leukopenia or thrombocytopenia.
• Acute renal failure: especially in patients with pre‑existing kidney disease.

When prescribing Indapamide, clinicians should consider several safety measures.

• Monitor electrolytes: regular blood tests to detect potassium or sodium changes.
• Assess renal function: adjust therapy if creatinine clearance is reduced.
• Evaluate blood pressure: avoid excessive hypotension, especially in the elderly.
• Use caution in diabetes: monitor glucose as the drug may raise blood sugar.
• Discontinue if hypersensitivity occurs: stop immediately upon signs of allergic reaction.
• Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Indapamide interacts with several drug classes; some require avoidance while others need close monitoring.

Major Interactions (Avoid)

• Lithium: increased lithium toxicity.
• NSAIDs: reduced diuretic efficacy and possible renal impairment.
• ACE inhibitors or ARBs: heightened risk of renal dysfunction and hyperkalemia.
• Other thiazide diuretics: additive electrolyte loss.
• Digoxin: enhanced digoxin toxicity due to electrolyte shifts.

Moderate Interactions (Monitor Closely)

• Antihypertensives: additive blood‑pressure lowering effect.
• Corticosteroids: increased potassium loss.
• Antidiabetic agents: possible alteration of glucose control.
• Calcium supplements or vitamin D: risk of hypercalcemia.
• Alcohol: may exacerbate dizziness and hypotension.
