OBJECTIVE: To report plasma moclobemide, course and outcome of two cases of overdose with moclobemide alone and one case of combined ingestion of moclobemide and clomipramide. METHODS: Moclobemide identification and quantification was achieved by gas chromatography-mass spectrometry after alkaline extraction. CASE REPORTS: In case 1, plasma moclobemide was 2.8 mg/L with 1.8 mg/L clomipramide; in case 2, 18 mg/L; in case 3 60.9 mg/L and 4.6 mg/L 12 hours later. None of the patients showed serious effects during 24 hours of observation. Plasma moclobemide at 10 to 30 times therapeutic was not associated with major toxic effects. Moclobemide seems to be considerably less toxic than tricyclic antidepressants.
