The metabolites of naproxen produced by Cunninghamella species were isolated and identified, and further to compare the similarities between microbial transformation and mammalian metabolism. Naproxen was transformed by three strains of Cunninghammella species (Cunninghamella blakeslesna AS 3.153, Cunninghamella echinulata AS

Interference by naproxen in the spectrophotometric assay for urinary 5-hydroxyindoleacetic acid has been investigated. Gas chromatography-mass spectrometry demonstrated that ingestion of naproxen was associated with the production of four urinary components, unchanged drug and three metabolites, the major one being
