Abstract A rapid capillary electrophoresis method for the quantification of gabapentin, a new anticonvulsant drug, in serum was developed. The assay involves derivatization of gabapentin with fluorescamine to provide a chromophore for UV-fluorescence detection. The migration time is about 11 min. The assay was linear between 0 and 20 mg/l. No other therapeutic drugs or amino acids interfered with the gabapentin peak. The relative standard deviation is 2.4\% at a mean of 11 mg/l (n = 17). The mean serum level for 52 patients on this drug was 5.2 mg/l with a range of 0-12 mg/l.
