Chlorthalidone

Chlorthalidone is a medication primarily used to treat high blood pressure (hypertension) and manage fluid retention in conditions like heart failure, kidney disease, or cirrhosis. It belongs to a class of drugs known as thiazide diuretics. Chlorthalidone helps reduce the amount of salt and water retained in the body, lowering blood pressure and reducing swelling. By improving fluid balance, it also helps prevent complications related to fluid retention, such as swelling in the legs and ankles.

Uses of Chlorthalidone

Chlorthalidone is used for the following conditions:

• High blood pressure (hypertension)
• Fluid retention (edema) due to heart failure, kidney disease, or liver disease
• Prevention of strokes, heart attacks, and kidney problems in hypertensive patients

How Chlorthalidone Works

Chlorthalidone works by blocking the reabsorption of sodium and chloride in the kidneys, causing the body to excrete more salt and water through urine. This helps lower blood pressure by reducing the volume of fluid in the blood vessels and alleviates symptoms of edema by reducing fluid buildup in tissues.

Benefits of Chlorthalidone

The key benefits of Chlorthalidone include:

• Effective in reducing high blood pressure
• Helps manage fluid retention, improving symptoms of swelling
• Reduces the risk of heart-related complications such as heart attack and stroke
• Long-lasting effects for consistent blood pressure management
