Abstract

Steroid compounds processing a hydrogen donor in 3beta position, either in the form of a hydroxy- or a sulfate group, function as efficient blockers of the 3alpha-hydroxy-pregnan-steroid action and thus have utility as therapeutic substances for the prevention and/or treatment of steroid related CNS disorders. Treatment methods based on the administration of these substances are disclosed, and these substances either alone or in combination are also suggested for the manufacture of pharmaceuticals for the treatment of many specific steroid induced CNS disorders.
