Compounds exhibiting 3alpha-hydroxy-5alpha/beta-steroid blocking action with no or only low antagonism against the gamma-aminobutyric acid (A) receptor (GABA-A), and compounds exhibiting partial antagonism against said receptor are presented. Methods for the prevention, treatment and/or alleviation of various CNS-disorders are suggested, as well as pharmaceutical compositions for such use.

GABA-steroid antagonists and their use for the treatment of CNS disorders

Steroid compounds possessing 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.

Pregnane steroids and their use in the treatment of CNS disorders

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.

The use of epiallopregnanolone (3&bgr;-hydroxy-5&agr;-pregnan-20-one) for the treatment of steroid induced mood disorders and CNS disorders is disclosed. Further, the use of epiallopregnanolone for the manufacture of pharmaceuticals is disclosed, together with an list of symptoms suitable for treatment with epiallopregnanolone.
