63Ni electron-capture gas chromatographic assay for buprenorphine and metabolites in human urine and feces.

Abstract

A 63Ni electron-capture gas chromatographic assay is described for buprenorphine, a potent narcotic agonist--antagonist. In addition, the assay is useful for the measurement of the metabolite norbuprenorphine and demethoxybuprenorphine, a rearrangement product resulting when buprenorphine is exposed to acid and heat. An extraction procedure was developed… (More)
