What is Zurzuvae?

Zurzuvae (zuranolone) is used to treat postpartum depression (PPD), it is a rapid-acting, once-daily capsule taken for 14 days. Zurzuvae works quickly to improve depression symptoms compared to current treatment options, which may take weeks or months to work. Zurzuvae is the first oral medication FDA-approved to treat postpartum depression.

Zurzuvae is the brand name for zuranolone, and during development, it was called SAGE-217 and BIIB125.

Postpartum depression is a major depressive episode that can occur after childbirth but can also start during the later stages of pregnancy. PPD is a serious condition in which women may feel intense anxiety, sadness, shame, guilt, problems sleeping, stress, panic attacks, and suicidal thoughts or attempts. This can make it difficult for mothers to care for and bond with their babies and may delay the child's physical and emotional development.

Is Zurzuvae FDA approved?

Yes, Zurzuvae received FDA approval to treat adults with postpartum depression on August 04, 2023. The application for FDA approval was supported by the LANDSCAPE and NEST clinical trials.

How does Zurzuvae work?

Zurzuvae is a neuroactive steroid (NAS) GABA-A receptor positive allosteric modulator (PAM).

Zurzuvae is thought to work by rebalancing brain networks responsible for functions such as mood, arousal, behavior, and cognition. Some health conditions, such as depression, are thought to be due to imbalances in GABA (Gamma-aminobutyric acid). GABA is a chemical messenger (neurotransmitter) in the brain and spinal cord (central nervous system). Zurzuvae is a neuroactive steroid that acts on the GABA-A receptors as a positive allosteric modulator.

Zurzuvae was developed as an improvement to brexanolone (Zulresso), which is only available as an intravenous injection, whereas Zurzuvae can be taken as a once-daily capsule.

How effective is Zurzuvae?

A clinical trial called Study 1 (NCT04442503) looked into the effectiveness of Zurzuvae 50mg for treating postpartum depression in adults. The study found that women who took Zurzuvae 50mg daily for 2 weeks experienced a statistically significant reduction in depressive symptoms by day 15. The symptoms were measured using the 17-item Hamilton Rating Scale for Depression (HAMD-17).
