[Fluorometric method for the determination of naproxen and demethylnaproxen in serum and urine (author's transl)]. 1978

H Held

Naproxen and demethylnaproxen can be determined fluorometrically in serum and urine after extraction with dichlorethane, and without prior separation. The detection limit of naproxen and demethylnaproxen is below 0,2 mg/l in serum and below 0,5 mg/l in urine. After incubation of urine with beta-glucuronidase/arylsulfatase, most of the conjugated naproxen and demethylnaproxen can be determined.
