Indapamida Slavia (Indapamide)

• Indapamide is indicated for conditions that involve elevated blood pressure or fluid overload, acting as a diuretic and antihypertensive agent.
• Hypertension: reduces peripheral vascular resistance and plasma volume, leading to sustained lowering of systolic and diastolic blood pressure.
• Edema associated with heart failure: increases urinary sodium and water loss, helping to relieve pulmonary and peripheral congestion in chronic heart failure patients.
• Edema associated with renal disease: facilitates fluid removal in nephrotic syndrome or chronic kidney disease, decreasing peripheral edema and improving symptom control.

• Indapamide acts on the distal convoluted tubule of the nephron by inhibiting the Na⁺/Cl⁻ cotransporter. This blockade reduces sodium and chloride reabsorption, leading to increased urinary excretion of water. The resulting decrease in extracellular fluid volume lowers cardiac output, while a significant direct vasodilatory effect on arteriolar smooth muscle reduces peripheral vascular resistance, together contributing to its antihypertensive action overall.

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

Common Side Effects

• Electrolyte imbalance (e.g., low potassium): may cause mild dizziness, muscle cramps, or fatigue due to altered potassium levels.
• Increased urination: patients often experience a frequent need to void, especially during the first weeks of therapy.
• Headache: a mild to moderate intensity headache may occur, typically transient and responsive to simple analgesics.
• Dry mouth or thirst: sensation of reduced salivation leading to increased thirst and discomfort.

Serious or Rare Side Effects

• Severe dehydration: marked fluid loss can lead to hypotension, dizziness, and in extreme cases, syncope.
• Acute kidney injury: sudden decline in renal function may present with elevated creatinine and reduced urine output.
• Allergic reactions: rash, pruritus, or angioedema may develop, requiring immediate medical attention.
• Blood dyscrasias: leukopenia or thrombocytopenia can occur, presenting with increased infection risk or bleeding tendencies.

• When prescribing Indapamide, clinicians should consider several precautionary measures to minimize risk.
• Renal function: assess baseline creatinine and monitor during therapy.
• Electrolytes: check serum potassium and sodium before initiation and periodically.
• Hypotension: monitor blood pressure, especially in patients also receiving other antihypertensives.
• Gout: use cautiously in patients with a history of gout, as uric acid levels may rise.
• Pregnancy and lactation: avoid unless benefits outweigh potential risks, due to limited safety data.
• Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture.

Indapamide can interact with several medicines, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Lithium: concomitant use may increase lithium serum concentrations, raising the risk of lithium toxicity and neurological symptoms.
• NSAIDs: may blunt indapamide’s natriuretic effect and impair renal perfusion, reducing diuresis.
• ACE inhibitors or ARBs: combined therapy can cause excessive reduction in blood pressure and may precipitate acute kidney injury, especially in volume‑depleted patients.

Moderate Interactions (Monitor Closely)

• Beta‑blockers: additive antihypertensive effect may cause symptomatic hypotension; monitor blood pressure and adjust doses
