Determination of Sulfonylureas and Metabolites by Pyrolysis Gas Chromatography

Vijay Aggarwal 1 and Irving Sunshine 1

1 Cuyahoga County Coroner's Office and the Institute of Pathology, School of Medicine, Case Western Reserve University, Cleveland, Ohio 44106.

We describe a simple, rapid method for determination of sulfonylureas that is not susceptible to significant interference from metabolites. An acidified plasma is extracted with toluene, followed by a back extraction from the toluene to methanolic trimethylanilinium hydroxide. The resulting compounds are measured by gas chromatography.
