Arms Assigned Interventions
Placebo Comparator: Vehicle without ANESDERM (lidocaine, prilocaine) Drug: Microdialysis of fluconazole, vehicle and N(G)-nitro-L-arginine-methyl ester (L-NMMA)
At the first three visits, volunteers will receive fluconazole (650µmol/L and 6.5mmol/L) and vehicle (NaCl 0.9%), and at the fourth, these plus L-NMMA (10mmol/L), delivered by microdialysis in the forearm, with or without anesthesia. Then post-occlusive hyperemia and thermal hyperemia are performed.
Active Comparator: Vehicle with ANESDERM (lidocaine, prilocaine) Drug: Microdialysis of fluconazole, vehicle and N(G)-nitro-L-arginine-methyl ester (L-NMMA)

Detailed Description:

The EETY study is a single-center proof of concept study in healthy volunteers. The main objective is to study the involvement of epoxy-eicosatrienoic acids (EETs) in the reactivity of cutaneous microcirculation during post-occlusive hyperemia and thermal hyperemia, by studying the response to microdialysis of fluconazole (an inhibitor of EETs) versus control, on the forearm.

Response is measured by the amplitude of the post-occlusive hyperemia and thermal hyperemia peaks (maximum amplitude as a percentage of maximal vasodilation and areas under the curve: AUC) during the injection of fluconazole compared to an intradermal injection of solvent (NaCl 9 ‰).

The subjects are healthy volunteers of both sexes, aged between 18 and 35, non-smokers and in good health. Over two years, 30 subjects will be included in the study for 6 to 13 weeks.
