Poster presented at 2009 American College of Clinical Pharmacology conference in Orlando. April 24-28.
Background: About 55 to 94% of infants born to opioid dependent mothershave neonatal abstinence syndrome (NAS). Buprenorphine (BUP) is usedclinically as an analgesic and a detoxification agent and a maintenancetreatment for opioid dependence. No data, however, has been reported about the use of sublingual administration of BUP below the age of 4 year, especially for term infants with NAS.
Objectives: Characterize pharmacokinetics (PK) of BUP in newborn patients;Evaluate the developmental changes in newborns in order to assist dosingoptimization in ongoing clinical studies.
Methods: In silico prediction …
