✦ Synopsis

A method has been developed for the blood level determination of the antihypertensive agent tiamenidine hydrochloride. The serum samples are mixed with deuterium labelled tiamenidine hydrochloride as an internal standard and extracted with methylene chloride. The extracts are derivatized with heptafluorobutyric acid anhydride and andysed by means of gas chromatography mass spectrometry using the selected ion monitoring technique to measure the molecular ion intensities of the bk-heptafluorobutyryl derivatives of tiamenidine hydrochloride and of the internal standard. Using 5 ml serum, the limit of detection is 0.2 ng I & ' with an accuracy of *0.17 ng (Syx of the calibration curve).
