Benzarone is primarily used in the treatment of chronic venous insufficiency, a condition where the veins in the legs have difficulty returning blood to the heart. It works by improving venous tone and reducing capillary permeability, which helps alleviate symptoms such as swelling, pain, and heaviness in the legs. Additionally, Benzarone has been explored for its potential antioxidant properties, which may contribute to its therapeutic effects by protecting blood vessels from oxidative stress. It is often administered orally and is commonly prescribed in combination with other treatments to enhance its efficacy in managing venous disorders.
