Open Label Treprostinil Raynaud's Study

Raynaud's phenomenon is a condition where the blood vessels in participants fingers and toes get too narrow when cold or stressed. This makes participants fingers and toes change colors - they might turn white, then blue, and finally red as blood flow returns. It can be painful and cause numbness or tingling. When participants have Raynaud's, blood vessels react too strongly to cold or stress. Fingers and toes may turn white (blood moves away from the area), blue (lack of oxygen), or red and feel painful or tingly when warming up. These episodes usually last from a few minutes to several hours. There are two types of Raynaud's. Primary Raynaud's (also called Raynaud's disease) itself and isn't connected to other health problems. It's the most common type and affects mostly women under 30. Secondary Raynaud's (also called Raynaud's phenomenon) is caused by other diseases like lupus, scleroderma, or rheumatoid arthritis. This type tends to be more serious and may cause painful sores on fingertips called digital ulcers. For mild cases, staying warm might be enough. But if symptoms are severe, participants doctor might prescribe various medications including calcium channel blockers - blood pressure medicines that help open blood vessels, or other vasodilators - medicines that widen blood vessels. About 40% of people with scleroderma develop painful sores on their fingertips called digital ulcers. These happen when there isn't enough blood flow to heal small injuries. For sev…
