Indapril 4 mg is an antihypertensive medication that contains Indapamide, a thiazide-like diuretic primarily used to manage high blood pressure (hypertension) and to treat edema associated with heart failure. It works by promoting the excretion of sodium and water through the kidneys, which helps to reduce blood volume and lower blood pressure. Additionally, Indapril aids in relaxing blood vessels, improving overall blood flow and reducing the strain on the heart. This medication is often prescribed as part of a comprehensive treatment plan that may include lifestyle modifications and other antihypertensive agents. Common side effects can include dizziness, increased urination, and potential electrolyte imbalances. Patients are advised to follow their healthcare provider's instructions regarding dosage and monitoring, particularly if they have pre-existing health conditions.
