Comment on "a comparison of buprenorphine + naloxone to buprenorphine and methadone in the treatment of opioid dependence during pregnancy: maternal and neonatal outcomes".

In a recent article, Lund et al sought to compare maternal and neonatal outcomes of various treatment regimens for opioid dependence during pregnancy.1 In their background, discussion the authors state that "In the United States buprenorphine plus naloxone [Suboxone(®)] … has been the preferred form of prescribed buprenorphine due to its reduced abuse liability relative to buprenorphine alone [Subutex(®)]." This claim is certainly consistent with the view of the firm that has manufactured and sold both products, Reckitt Benckiser.
