Clonidine as Adjunct to Morphine for Neonatal Abstinence Syndrome

Neonatal abstinence syndrome (NAS) is an emerging epidemic and has lead to a tremendous increase in cost of medical care. Opioids are the mainstay of treatment for NAS although there are concerns about possible short-term and long-term effects including but not limited to adverse neurodevelopmental outcomes. Other drugs such as clonidine, phenobarbitone, methadone and buprenorphine have been evaluated to limit the postnatal exposure to opioids in these infants. Clonidine is an alpha 2 receptor and can lessen withdrawal manifestations. The addition of clonidine at 6 µg/kilogram/day to morphine in the management of NAS has been shown to reduce the duration of pharmacotherapy by about 27% in a previous study. A recent pilot study reported reduction of treatment duration for NAS with clonidine (12 µg/kilogram/day) monotherapy as compared to morphine monotherapy. The study reported no adverse effects in study subjects at the doses used in the study. The investigators hypothesize that there will be a minimum of 30% reduction in the treatment duration with 12 µg/kilogram/day clonidine used as adjuncts to standard morphine treatment as compared to morphine monotherapy in the management of term and near term infants with NAS
