Primary Outcome Measures:
  • Improvement in endothelium-dependent vasodilation of the microcirculation of the skin and nerve axon-related reflex vasodilation. [ Time Frame: 4 weeks ]
  • Improvement in endothelium-dependent vasodilation of the brachial artery (flow mediated dilation) [ Time Frame: 4 weeks ]
  • Improvement in selective measurements of oxidative stress, endothelial activity and vascular abnormalities which will correlate with PKC activity in the peripheral monocytes. [ Time Frame: 4 weeks ]

Secondary Outcome Measures:
  • Safety of ruboxistaurin [ Time Frame: 4 weeks ]

Enrollment: 30
Study Start Date: December 2003
Study Completion Date: March 2005
Detailed Description:
32mg Ruboxistaurin; 4 week cross-over treatment.
