Where zuranolone fits into the treatment algorithm for severe PPD
Many clinicians who support women with PPD will wonder, upon hearing this news, where zuranolone fits into the treatment algorithm for severe postpartum major depression. Some relevant issues that may determine the answer are the following:
Cost. The cost of brexanolone was substantial, at $34,000 per year, and was viewed by some as a limiting factor in terms of its very limited uptake. As of this column’s publication, zuranolone’s manufacturer has not stated how much the medication will cost.
Breastfeeding. Unlike selective serotonin reuptake inhibitors, which have been demonstrated to be effective for the treatment of PPD and safe during pregnancy and lactation, we have sparse data on the safety of zuranolone for women who wish to breastfeed. It is also unclear whether women eligible for zuranolone would, based on the limited data on safety in lactation, choose deferral of breastfeeding for 14 days in exchange for treatment.
Duration of treatment. While zuranolone was studied in the context of 14 days of acute treatment, then out to day 42, we have no published data on what happens on the other side of this brief interval. As a simple example, in a patient with a history of recurrent major depression previously treated with antidepressants, but where antidepressants were perhaps deferred during pregnancy, is PPD to be treated with zuranolone for 14 days? Or, hypothetically, should it be followed by empiric antidepressant treatment at day 14? Alternatively, are patient and clinician supposed to wait until recurrence occurs before pursuing adjunctive antidepressant therapy whether it is pharmacologic, nonpharmacologic, or both?
Treatment in patients with bipolar disorder. It is also unclear whether treatment with zuranolone applies to other populations of postpartum women. Certainly, for women with bipolar depression, which is common in postpartum women given the vulnerability of bipolar women to new onset of depression or postpartum depressive relapse of underlying disorder, we simply have no data regarding where zuranolone might fit in with respect to this group of patients.
The answers to these questions may help to determine whether zuranolone, a new antidepressant with efficacy, quick time to onset, and a novel mechanism of action is a “game changer.” The article in The Wall Street Journal provided me with some optimism, as it gave PPD and the issues surrounding PPD the attention it deserves in a major periodical. As a new treatment, it may help alleviate suffering at a critical time for patients and their families. We are inching closer to mitigation of stigma associated with this common illness.
Thinking back across the last 3 decades of my treating women suffering from PPD, I have reflected on what has gotten these patients well. I concluded that , along with family and community-based support groups, as well as a culture that reduces stigma and by so doing lessens the toll of this important and too frequently incompletely-treated illness.
