title: [Determination of bumadizone, phenylbutazone and oxyphenbutazone in human plasma by high-performance liquid chromatography (author's transl)].
abstract: HPLC methods are described to determine bumadizone, phenylbutazone and oxyphenbutazone in human plasma. The procedure for the determination of phenylbutazone and oxyphenbutazone is based on a microphase extraction and especially suitable for routine analyses because of its simplicity and rapidity. 0.5 microgram of the compounds per milliliter plasma can easily be determined; the relative standard deviations of the methods are between 0.7 and 4.4% at therapeutic plasma concentrations.
