Tadalafil for the Treatment of Raynaud's
Tadalafil for the Treatment of Secondary Raynaud's Phenomenon

The investigators propose that tadalafil will increase digital blood flow and improve the symptoms and signs of secondary Raynaud's phenomenon.

The primary goal of our study is to decrease the frequency, duration and severity of vasospastic attacks in patients with secondary Raynaud's. The secondary goal is to document increased blood flow and lessened capillary dysfunction in these patients. Both of these goals are to be achieved using a course of treatment with Tadalafil.We anticipate a decrease in the frequency, duration and severity of Raynaud's attacks. Improved digital blood flow and digital blood pressures, and a decrease in digital capillary dysfunction.
