Indapamide is primarily used as a diuretic to treat high blood pressure (hypertension) and fluid retention (edema) caused by heart failure. It works by helping the kidneys remove excess salt and water from the body, which reduces blood pressure and alleviates swelling. This medication is often prescribed as part of a long-term management plan for hypertension, as it helps maintain stable blood pressure levels. Additionally, it may be combined with other antihypertensive drugs for enhanced effectiveness. Indapamide is also beneficial in managing conditions like congestive heart failure, where reducing fluid buildup is crucial for improving heart function and overall health. It is typically taken orally in tablet form, with dosage adjusted based on the patient's response and medical condition.
