Isoxsuprine is a drug for  treating diseases with impaired blood flow, such as Raynaud's disease, arteriosclerosis, Buerger's disease , or cerebral vascular insufficiency. This drug is available in tablet and injection form.

Isoxsuprine works by dilating blood vessels so that blood can flow more smoothly to body tissues, including the hands, feet and brain. This way of working can help reduce the symptoms of numbness , tingling, and memory loss that occur due to a lack of oxygen intake in the tissues.

In addition to dilating blood vessels, isoxsuprine also has a relaxing effect on the uterine muscles (tokolytic). Therefore, this drug can also be used to reduce contractions in pregnancies with a risk of preterm labor.
