research Studies on Neurosteroids XXV. Influence of a 5.ALPHA.-Reductase Inhibitor, Finasteride, on Rat Brain Neurosteroid Levels and Metabolism
In this study, finasteride dose-dependently inhibited stress-induced increases in allopregnanolone in rats, while enhancing 20alpha-reduction of progesterone without affecting 3alpha-dihydroprogesterone or 11-deoxycorticosterone levels.
