Duvadilan Tablet contains Isoxsuprine, a medicine used to improve blood circulation and relax smooth muscles in the body. It is commonly prescribed to support better blood flow in circulatory problems and to help relax uterine muscles in certain pregnancy-related conditions like premature labor (as advised by a doctor). This medicine works by widening blood vessels, which helps improve oxygen and nutrient flow throughout the body. Better circulation may help reduce symptoms linked with poor blood flow, such as cold extremities, numbness, or discomfort.
