Popis: A method based on liquid chromatography-tandem mass spectrometry and microbore column separation was developed for the quantification of a potent 5-HT2a receptor antagonist (R)-(+)-α-(2,3-dimethoxyphenyl)-1-[2-(4-fluorophenyl)etnyl]-4-piperidine-methanol (I) and the desmethyl metabolite (II) in rat brain extracellular fluid (ECF) following microdialysis sampling. The analytical method was also applied to determining plasma concentrations of these compounds. The lower limit of quantification (LLQ) for each compound in microdialysis perfusate is 500 pg/mL, which translates to
