Whereas we’ve got recognized about neuroactive results of steroids for the reason that 1940s, it has been troublesome to copy the helpful results of naturally produced neurosteroids with related compounds synthesized within the laboratory.  A number of completely different neurosteroids have been examined as anticonvulsants and anaesthetic brokers; nonetheless, we’ve got seen probably the most  sturdy medical findings with a number of completely different derivatives of allopregnanolone used as antidepressants.   Certainly one of these allopregnanolone analogues, brexanolone, was accepted final yr by the FDA for the remedy of extreme postpartum melancholy and is now being marketed as Zulresso (Sage Therapeutics).

Its metabolite pregnenolone sulfate is just like brexanolone and acts as a unfavorable allosteric modulator of the GABA-A receptor and can be a constructive allosteric modulator of the NMDA receptor.

Each preclinical and human knowledge counsel that pregnenolone could also be a promising remedy for melancholy. Dr. Freeman’s examine will check the effectiveness of pregnenolone in ladies with menopausal melancholy.
