What You Need to Know

In infants with neonatal abstinence syndrome, sublingual buprenorphine reduced the duration of treatment, decreased the length of hospital stay, and had a similar rate of adverse events when compared with oral morphine.

Trial Design

  • Double-blind, double-dummy study compared sublingual buprenorphine with oral morphine in the treatment of neonatal abstinence syndrome
  • 63 infants (37 weeks gestation) who were exposed to opioids during pregnancy and displayed signs of the neonatal syndrome were randomized to receive buprenorphine or morphine
  • Adjunctive phenobarbital was utilized in infants with uncontrolled symptoms despite receiving the maximum dose of opioid
  • Primary endpoint: “duration of treatment for symptoms of neonatal opioid withdrawal
  • Secondary endpoints: hospital stay length, percent of infants requiring adjunctive phenobarbital treatment, safety

Key Outcomes:

  • Shorter median duration of treatment observed in buprenorphine patients vs morphine patients (15 days vs 28 days, respectively;<.001)
  • Median length of hospital stay was 21 days for buprenorphine patients vs 33 days for morphine patients (<.001)
  • 15% of buprenorphine patients (5 out of 33) received adjunctive phenobarbital vs 23% of morphine patients (7 out of 30) (=.36)
  • Similar rates of adverse events observed between the 2 groups
