Summary
The long term goals of our research are to establish the best pharmacological treatment for NAS and determine how pharmacologic treatment of NAS affects long-term developmental outcomes. The objective of this application is to evaluate the effectiveness of clonidine as a treatment for neonates with NAS, in a randomized clinical trial. Our central hypothesis is that clonidine will effectively treat drug withdrawal manifestations in neonates.
