Narva Sr (Indapamide)

• Indapamide belongs to the thiazide‑like diuretic class and is employed in the management of conditions related to excess fluid and high blood pressure.
• Hypertension: reduces systolic and diastolic blood pressure in patients with primary hypertension.
• Edema: promotes diuresis to decrease peripheral and pulmonary fluid accumulation.
• Congestive heart failure: assists in controlling fluid overload and improving symptomatic relief.

• Indapamide inhibits sodium‑chloride reabsorption in the distal convoluted tubule of the nephron, leading to increased urinary excretion of sodium, chloride, and water. This natriuretic effect lowers extracellular fluid volume, reduces peripheral vascular resistance, and consequently decreases arterial blood pressure.

Indapamide may cause a range of adverse reactions, from mild to serious. Patients should be aware of the potential side‑effect profile.

Common Side Effects

• Dizziness or light‑headedness
• Headache
• Increased urinary frequency
• Electrolyte imbalance, especially low potassium
• Fatigue or weakness
• Nausea or abdominal discomfort

Serious or Rare Side Effects

• Severe dehydration or volume depletion
• Significant electrolyte disturbances (hypokalemia, hyponatremia)
• Allergic reactions such as rash, itching, or angioedema
• Acute renal impairment or failure
• Gout attacks due to uric acid elevation
• Blood dyscrasias including leukopenia or thrombocytopenia

Before initiating therapy, clinicians should evaluate patient‑specific factors and monitor relevant parameters.

• Blood pressure monitoring: ensure adequate control and avoid hypotension.
• Electrolyte assessment: regularly check serum potassium and sodium levels.
• Renal function: adjust use in patients with impaired kidney function.
• Hypersensitivity: discontinue if allergic reactions occur.
• Diabetes: monitor glucose as diuresis may affect glycemic control.
• Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Indapamide can interact with several drug classes, altering efficacy or safety.

Major Interactions (Avoid)

• Lithium: increased lithium toxicity due to reduced renal clearance.
• Cyclosporine: heightened risk of nephrotoxicity and electrolyte imbalance.
• Other potent diuretics: may cause severe volume depletion and electrolyte disturbances.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: additive blood‑pressure‑lowering effect, monitor for hypotension.
• Digoxin: risk of increased serum digoxin levels secondary to hypokalemia.
• Antidiabetic agents: enhanced hypoglycemic effect, require glucose monitoring.
• Corticosteroids: may exacerbate potassium loss, necessitate electrolyte surveillance.
