The concentration of a novel anticonvulsant, 2,3:4,5-bis-O-(1-methylethylidene)-beta-D-fructopyranose sulfamate (topiramate), was determined in the extracellular fluid of rat brain by in vivo microdialysis combined off-line with liquid chromatography/thermospray mass spectrometry. A microdialysis probe was stereotaxically implanted in the nucleus accumbens region of the rat brain. The maximum concentration of topiramate in the brain dialysate for a dose of 50 mg kg-1 i.v. was approximately 10 microM and occurred 45 min post-injection. The detection limit of topiramate in the extracellular fluid of rat brain was in the 0.1 microM range using selected ion monitoring techniques. The base peak, which was the ammonium adduct ion [M + NH4]+, was used for detection. An internal standard of d12-labeled topiramate was utilized for quantitation by isotope dilution analysis.
