This study will assesses the efficacy of buprenorphine/naloxone vs buprenorphine on maternal withdrawal symptoms and drug cravings.
This is a randomized controlled trial to a cohort of pregnant women seeking medication-assisted treatment for opioid use disorders. Half of participants will receive buprenorphine, while the other half of participants receive a combination of buprenorphine/naloxone
Buprenorphine and Buprenorphine/naloxone each are used to treat opioid use disorders in pregnancy.
Buprenorphine has many preferential characteristics over methadone including decreased risk of maternal overdose, lower incidence of preterm labor, less frequent clinical visits, shorter duration of neonatal hospital stay and treatment for neonatal abstinence syndrome. Recent studies have found that increasing the dosing frequencies of buprenorphine is more efficacious to prevent maternal withdrawal symptoms, improve compliance, and theoretically produce better pregnancy outcomes.
Buprenorphine/naloxone, a combination opioid of buprenorphine and naloxone, has also been investigated as an alternative to treatment and maintenance for opioid use disorder. The advantage of the combination of buprenorphine with naloxone is that it reduces the potential for abuse. As a partial mu opioid agonist, buprenorphine alone has the capacity to induce typical opioid effects such as euphoria, which are enhanced when the drug is taken intravenously. By combining buprenorphine with naloxone, an opioid antagonist, the capacity for buprenorphine to be abused is reduced.

| Measure | Description | Time Frame |
|---|---|---|
| Compliance antepartum | To compare compliance with buprenorphine versus buprenorphine/naloxone medication-assisted treatment (MAT) in pregnant women. Compliance will include the incidence of urine toxicology testing positive for illicit substances during prenatal care and at the time of admission for delivery. | From entry into the study until delivery (through study completion, an average of 9 months which is duration of the pregnancy) |
| Compliance postpartum | To compare compliance with buprenorphine versus buprenorphine/naloxone medication-assisted treatment (MAT) in the postpartum period. Compliance will include the incidence of urine toxicology testing positive for illicit substances from the time of discharge from the hospital following the delivery over a 2 month period postpartum (postpartum period). | 2 month period postpartum |
| Dosing antepartum | Evaluate all women for the need a significant dosing change in buprenorphine or buprenorphine/naloxone (>50% increase or decrease) during pregnancy. | From entry into the study until delivery (through study completion, an average of 9 months which is duration of the pregnancy) |
| Dosing postpartum | Evaluate all women for the need a significant dosing change in buprenorphine or buprenorphine/naloxone (>50% increase or decrease) from the hospital following the delivery over a 2 month period postpartum (postpartum period). | 2 month period postpartum |
| Measure | Description | Time Frame |
