|Mechanically Ventilated Neonates, Painful Procedures in Newborns||Drug: Codeine||Phase 1|
This proposal has its origins in a larger initiative to elucidate the pharmacological basis for the interindividual differences observed in opioid responsiveness. Gaps in our knowledge related to opioid disposition in newborns need to be addressed to complete the design of the required overarching initiative in which age could be treated as a continuous variable within a context of PK, PD and PG determinants.This proposal is designed to generate preliminary data that addresses two issues. First, can newborns absorb enterally administered codeine and is this ability determined by PCA or PNA age? The second relates to the ability of newborn infants to catalyze those reactions required to metabolically activate both codeine and morphine. The latter will also be evaluated within the context of PCA versus PNA age.
These data will not only fill an information gap that must be addressed before the larger initiative moves forward, but they also provide a platform for serious study of the ontogeny of certain pharmacokinetic processes that may prove critical to our understanding of newborn drug disposition. In this way, codeine can provide important insights concerning the ontogeny of drug disposition and permit the determination of the relative importance of PCA versus PNA ages to the functional expression of these processes.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||64 participants|

|Masking:||None (Open Label)|
|Official Title:||Absorption and Metabolism of Oral Codeine in Mechanically Ventilated Neonates|
|Study Start Date :||August 2008|
|Estimated Primary Completion Date :||July 2012|
Neonates 0-30 days, no more than 2,000 grams, receiving mechanical ventilation.
One single oral dose of 1 mg/kg of codeine
- The rate and extent of absorption of oral codeine, the ratios of the observed concentration of each metabolite to the observed concentration of parent drug and the formation and clearances of the metabolites. [ Time Frame: 2 hours ]
- Secondary outcomes include the additional PK parameters elimination half life, area under the curve and mean residence time. [ Time Frame: 2 hours ]
