A simple reversed-phase liquid chromatographic method enabling the simultaneous analysis in plasma of the tricyclic antidepressant clomipramine, its demethylated metabolite, and the selective serotonin reuptake inhibitor fluvoxamine, was developed: The drugs and dibenzepine, the internal standard, were extracted from 1 mL. plasma through an automated solid-phase procedure, eluted in a total chromatographic time of approximately 14 min and detected by means of an ultraviolet spectrophotometer preset at 254 nm. An assay sensitivity of 10 mu g/L was observed for all analytes, Recoveries for these drugs and their metabolites ranged between 65% and 98% and. their coefficient of variation (within-day and day-to-day) between 1.9% and 2.9%. In spiked plasma, within-day and day-to-day imprecision data were less than 5%. The simultaneous determination of clomipramine, N-desmethylclomipratnine, and fluvoxamine with adequate sensitivity and accuracy may be useful for the monitoring of drug treatment in depression and obsessive-compulsive disorder, where combinations of such drugs are employed.
