What this is
Sage Therapeutics/Biogen. First oral postpartum depression treatment (vs IV brexanolone/Zulresso 2019). 14-day course produces rapid sustained improvement.

Mechanism
Synthetic neurosteroid analog of allopregnanolone; positive allosteric modulator of synaptic and extrasynaptic GABA-A receptors; rapid normalization of GABAergic tone disrupted in postpartum depression
Dose & route
50 mg PO once daily x 14 days (with fat-containing meal)
