A method is described for the quantitative analysis of 6,11-dihydro-11-oxo-dibenz[b,e]-oxepin-2-acetic acid (isoxepac) in plasma and urine. Isoxepac and internal standard was analysed by gas-liquid chromatography using a flame ionization detector. The method is accurate and precise over the range 0.1--30 microgram/ml. The method has been applied to the analysis of plasma and urine from both healthy volunteers and patients receiving therapeutic oral doses of isoxepac.
