PRIMARY outcome

Timeframe: Duration of pharmacologic treatment for neonatal abstinence syndrome up to 70 days of age

Population: N/A (PK data was not usable as analyzed for this study as most was below the limit of quantification.)

Goal is to define buprenorphine pharmacokinetic exposure (Area under the plasma concentration versus time curve (AUC)) in infants treated with buprenorphine for neonatal abstinence syndrome (NAS) using a model-based optimized dose.

Outcome measures

Outcome data not reported

OTHER_PRE_SPECIFIED outcome

Timeframe: Duration of pharmacologic treatment for neonatal abstinence syndrome, up to 70 days of age

Population: Adverse events in study population
