Summary

Raynaud's phenomenon is thought to occur when, in response to cold or emotional stress, there is closure of the digital arteries and cutaneous arterioles leading to the clinical finding of sharp demarcated digital pallor and cyanosis of the distal skin of the fingers and/or toes. Patients often continue to experience problems despite current available treatment. The investigators' study will investigate the use of a new vasodilator called Fasudil, a Rho-kinase inhibitor. The investigators' hypothesis is that Fasudil will prevent vasoconstriction of digital and cutaneous arteries during a standard laboratory based cold exposure and will therefore improve digital blood flow and skin temperature recovery time following cold challenge. These data will provide the rationale for a more elaborate clinical trials in real life situations.

Conditions

  • Raynaud
  • Scleroderma

Interventions

DRUG

Fasudil

Each subject will be randomly assigned to 1 of 6 possible treatment sequences (ABC, ACB, BAC, BCA, CAB, and CBA) in a double-blind manner: A- a single oral dose of 2 placebo tablets; B- a single, oral 40 mg Fasudil dose as one 40 mg tablet and 1 placebo tablet; C- a single oral 80 mg dose as two 40 mg Fasudil tablets. Subjects will be randomized at the screening/baseline visit to a specific treatment sequence based upon a computer generated code on a 1:1:1:1:1:1 ratio for the 6 possible sequences. A single dose consisting of the two tablets will be taken after fasting for 10 hours once during each treatment period. A washout interval of at least 24 hours and no more than 7 days will be maintained between treatment periods. Concomitant medications will not be taken during the study session.
