Effects of Miconazole on Blood Flow
This study will investigate the effect of the drug miconazole on blood vessel dilation. Miconazole stops production of EDHF, a substance that causes arteries to dilate. EDHF is produced by the cells that line blood vessels.

- NCT00004575
- Testing
- Miconazole, L-NMMA, Bradykinin
- Where
- United States
- Volunteers
- 15 people, healthy volunteers welcome
