Abstract

Postpartum depression (PPD) presents as a major episode of depression occurring during pregnancy or within the initial weeks following childbirth. Despite varying opinions on the specific onset defining PPD, its symptoms significantly impair maternal-infant bonding, breastfeeding, and maternal function. Alongside typical depressive symptoms, anxiety and sleep disturbances often co-occur, leading to prolonged suffering and challenges in diagnosis. The pathophysiology involves dysregulation in neuroactive steroid levels, particularly allopregnanolone (ALLO), and disrupted GABA signaling post-delivery. This dysregulation is linked to altered stress response and has an association in PPD. Current pharmacologic treatments for PPD, primarily selective serotonin reuptake inhibitors (SSRIs), lack rapid response and specificity for PPD symptoms. Brexanolone, the first FDA-approved PPD treatment, mimics ALLO and has shown efficacy in reducing depressive symptoms, but with limitations in administration and potential side effects. Recent focus has turned to zuranolone, a synthetic neuroactive steroid GABAA receptor modulator that is distinct in that it can be taken once daily and is bioavailable orally. Preclinical studies demonstrated its potency in modulating GABAA receptors, highlighting its promise as a novel PPD treatment. Clinical trials on zuranolone showcased its safety, tolerability, and efficacy in improving depressive symptoms, anxiety, insomnia, and functional health among women with PPD. Notably, zuranolone's holistic benefits beyond targeting depression offer a promising breakthrough in the PPD treatment landscape. These findings emphasize the necessity for tailored interventions to enhance maternal mental health post-delivery. Continued research and development are crucial to expand treatment options and promote the well-being of mothers experiencing PPD.
