Naproxen Pharmacogenetic Study (Project 1, Aim 2)
Status unconfirmed · Phase 4
Conditions studied: Pharmacogenetics
In brief
This is a mechanism-based study in healthy adults to determine the effect of the CYP2C9 M1L gene polymorphism on the functional activity of the encoded CYP2C9 enzyme towards the probe substrate naproxen. CYP2C9 activity will be evaluated by measurement of O-desmethyl naproxen and unchanged naproxen in 24-hour urine following administration of a single oral dose of naproxen (Aleve) in Yup'ik Alaska Native adult men and women who were previously determined in a separate observational study to be homozygous for the CYP2C9\*1 allele or a carrier of the CYP2C9 M1L allele.
