A recent report indicated significant interference of naproxen with total bilirubin measurement when using the Jendrassik and Grof method. We explored the possibility of avoiding this interference by using a different method. We observed that naproxen has no effect on

Naproxen is metabolized in humans by O-demethylation, and by acyl glucuronidation to the 1-O-glucuronide. Naproxen, its metabolite and the conjugates can be measured directly by gradient high-performance liquid chromatographic analysis without enzymic deglucuronidation. The glucuronide conjugates were isolated by preparative
P J Guelen et al.
International journal of clinical pharmacology, therapy, and toxicology, 26(4), 190-193 (1988-04-01)
After a rectal dose of 500 mg in a suppository, naproxen is 6-O-demethylated (20%) and glucuronidated (40%), the metabolites are subsequently excreted renally. The elimination half-life is 15.2 +/- 2.6 h. Ten out of 22 subjects show biphasic elimination kinetics
