Review of clinical, observational, and preclinical studies on neuroactive steroids and GABAergic function.
Analysis of clinical trial data for brexanolone and zuranolone.
Discussion of GABAergic plasticity and stress-axis regulation in PPD.
Brexanolone and zuranolone demonstrate rapid onset of antidepressant effects with sustained benefits.
GABAergic modulation shows promise in addressing dysregulation associated with postpartum depression.
Evidence supports that these therapeutic agents may have broader applications in related psychiatric disorders.
