How ZURZUVAE Works

Zuranolone functions as a positive allosteric modulator of gamma-aminobutyric acid (GABA) A receptors. While the exact mechanism of action in treating postpartum depression is not fully understood, the drug is thought to achieve its therapeutic effect through this modulation. By acting on these specific biological targets, the medication influences the GABAergic system.
