[Ketoconazole antagonizes the immune and gonadotropic systems in the forced swimming test in male Wistar rats].

Disturbances in the activity of the corticotropic axis and immune system have been widely reported to be linked to the development of depression. The aim of this study was to explore the effects of ketoconazole, an imidazole derivative that inhibits gonadal and adrenal steroidogenesis, on changes in the total leukocyte count and the percentages of leukocyte subpopulations during the Porsolt forced swimming test (commonly used to measure the efficiency of antidepressants) in rats.
