How does it work?

Thymoxamine hydrochloride belongs to a class of medicines called the alpha blockers. It works by blocking alpha receptors in certain areas of the body. Alpha receptors are present on the muscle found in the walls of blood vessels. Blocking these receptors causes the muscle to relax and the blood vessels to widen. Thymoxamine is therefore useful in the treatment of Raynaud's disease, where there is narrowing of the blood vessels in the extremities, causing numbness and pain in the fingers and toes due to lack of blood supply. Widening the blood vessels results in an increase in the flow of blood to these areas, and so relieving the symptoms.
