Buprenorphine compared with methadone in opioid-dependent pregnant women: How does it affect neonatal abstinence

Background:
The growing opioid epidemic in the United States has led to increasingly high rates of neonatal abstinence syndrome (NAS). Preliminary studies have shown that buprenorphine maintenance treatment (BMT) may lead to better outcomes for infants than methadone maintenance treatment (MMT).
Objectives:
The authors gathered recent evidence to answer the following PICO (population, intervention, comparison, and outcome) question: In opioid-dependent pregnant women, how does buprenorphine compared with methadone administration affect NAS?
Data Sources:
A literature search was completed in PubMed, Scopus, Embase, and Web of Science databases and limited to the past 5 years. The following parameters were analyzed in the articles: NAS occurrence, length of hospital stay in days, NAS treatment length, and amount of pharmacotherapy administered to treat NAS.
Conclusions:
In comparison to methadone, buprenorphine exposure in utero is associated with significantly shorter hospital stays for the infant after delivery, shorter length of NAS treatment, and decreased frequency/duration of pharmacotherapy for NAS symptoms in the infant.
Implications For Practice:
Based on the findings, a weak recommendation can be made for the use of BMT over MMT in opioid-dependent pregnant women. However, further research is necessary to definitively recommend buprenorphine over methadone use in this population, especially regarding the effect of maternal severity of addiction on adherence to BMT, and long-term effects of in utero buprenorphine exposure.
