Icorvida Sr (Indapamide)

Indapamide is employed as a thiazide‑like diuretic to manage conditions characterized by elevated blood pressure or fluid overload.

• Hypertension: lowers systolic and diastolic blood pressure, reducing cardiovascular risk.
• Congestive heart failure‑related edema: promotes diuresis to decrease fluid retention and improve symptoms.
• Renal or hepatic edema: facilitates removal of excess fluid, aiding in volume control.

• Indapamide acts on the distal convoluted tubule of the nephron by inhibiting the sodium‑chloride symporter. This blockade reduces reabsorption of sodium and chloride, leading to increased excretion of water and electrolytes. The resulting mild diuresis lowers extracellular fluid volume and peripheral vascular resistance, which together contribute to a reduction in arterial blood pressure.

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

Common Side Effects

• Dizziness: sensation of light‑headedness, especially after standing.
• Increased urination: more frequent need to void.
• Electrolyte imbalance (low potassium): mild hypokalemia causing muscle weakness.
• Nausea: occasional stomach upset.

Serious or Rare Side Effects

• Severe dehydration: marked fluid loss requiring medical attention.
• Significant electrolyte disturbances: profound hypokalemia or hyponatremia.
• Allergic reactions: rash, itching, or swelling.
• Renal impairment: worsening kidney function in susceptible individuals.

When prescribing indapamide, clinicians should observe several safety considerations.

• Monitor electrolytes: check serum potassium and sodium regularly.
• Assess renal function: evaluate creatinine clearance before and during therapy.
• Use caution in the elderly: increased sensitivity to volume depletion.
• Avoid abrupt discontinuation: taper to prevent rebound hypertension.
• Concomitant lithium therapy: may increase lithium levels, requiring monitoring.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

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

Major Interactions (Avoid)

• Lithium: risk of lithium toxicity increases.
• NSAIDs (e.g., ibuprofen): may reduce diuretic effect and impair renal function.
• ACE inhibitors or ARBs: combined use can cause excessive potassium loss and hypotension.

Moderate Interactions (Monitor Closely)

• Digoxin: enhanced risk of digoxin toxicity due to electrolyte shifts.
• Corticosteroids: may counteract diuretic effect and increase fluid retention.
• Antidiabetic agents: hypoglycemia risk may be heightened.
