|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.
