Isoxsuprine 10mg/20mg is a vasodilator and beta-adrenergic agonist used primarily to relieve smooth muscle spasms and improve blood circulation. It is commonly prescribed to treat conditions like peripheral vascular disease and Raynaud’s phenomenon, where blood flow to the extremities is restricted. Isoxsuprine works by relaxing blood vessels and improving blood flow, which helps to reduce symptoms such as pain and cramping in the legs. It may also be used for conditions like premature labor as it has mild tocolytic effects (relaxes uterine muscles). Caution is recommended for use in people with cardiac conditions or hypertension, and it should be used under medical supervision.
