Raynaud's

Reduced blood flow in response to cold or emotional stress, causing discoloration of the fingers, toes, and occasionally other areas. May also cause nails to become brittle.

About Raynaud's

Raynaud's is a rare disorder that affects the arteries. Arteries are blood vessels that carry blood from your heart to different parts of your body.

Raynaud's sometimes is called a disease, syndrome, or phenomenon. The disorder is marked by brief episodes of vasospasm (VA-so-spazm), which is a narrowing of the blood vessels.

Vasospasm of the arteries reduces blood flow to the fingers and toes. In people who have Raynaud's, the disorder usually affects the fingers. In about 40 percent of people who have Raynaud's, it affects the toes. Rarely, the disorder affects the nose, ears, nipples, and lips.

Overview

There are two main types of Raynaud's—primary and secondary.

In primary Raynaud's (also called Raynaud's disease), the cause isn't known. Primary Raynaud's is more common and tends to be less severe than secondary Raynaud's.

Secondary Raynaud's is caused by an underlying disease, condition...Read more about Raynaud's

Iloprost and cisaprost for Raynaud's phenomenon in progressive systemic sclerosis

Scleroderma is a connective tissue disease causing fibrosis and commonly affects the skin and internal organs such as the GI tract, lungs, kidney and heart.

Cyclofenil is a drug that has been studied in the treatment for Raynaud's phenomenon and associated conditions. It is not used for RP and is an anabolic steroid. See also Cochrane review on Stanazol which is also an anabolic steroid.

Raynaud's phenomenon is a disease that causes decreased blood flow and circulation to patients' extremeties. Symptoms include discolouration, pain, and in some severe cases ulceration of the hands and feet. It is most often triggered by cold, stress, and emotional discomfort. Primary Raynaud's phenomenon has no underlying disease associated with it. Secondary Raynaud's phenomenon is most often associated with scleroderma, but may also be related to systemic lupus erythematosus, mixed connective tissue disease, Sjorgen's syndrome, dermatomyositis or rheumatoid arthritis.

Oral vasodilator drugs to reduce the symptoms of primary Raynaud's phenomenon

Raynaud's phenomenon is caused by short term constriction of the small arteries in the extremities, usually the fingers. For a few minutes, usually, the fingertips go white and feel numb or tingle and prickle. Then the blood flow returns and they become warm and red, which can also be painful. For some people the toes, ears, nose, tongue or nipples are affected. Cold or emotional stress can trigger the attacks. Keeping warm, stopping smoking and avoiding using tools that vibrate can prevent attacks but sometimes drug therapy is needed. Calcium channel blockers such as nifedipine are the drugs of choice but can have unwanted side effects.
