Summary
Ten patients with moderate to severe Raynaud's syndrome were recruited into a four week randomised double blind crossover study to compare the efficacy of UK-38,485 50 mg, a new thromboxane synthetase inhibitor with that of placebo. With the doses used there was no significant difference between the two treatment periods in the number, severity and duration of ischaemic attacks, the mean hand temperatures, forearm and digital blood flow and red blood cell rheology.
