Peripheral Vascular Disease (PVD): Pentoxifylline is commonly prescribed for individuals suffering from peripheral vascular disease, a condition characterized by narrowing or blockage of blood vessels in the arms, legs, or other peripheral areas of the body. By improving blood flow and circulation to affected limbs, pentoxifylline helps alleviate symptoms such as pain, cramping, and numbness, thereby enhancing the overall quality of life for patients with PVD.
