Popis: A rapid and simple high performance liquid chromatographic (HPLC) method to measure moclobemide and its N-oxide metabolite (Ro12-5637) in human urine has been developed by modifying an existing HPLC technique. Sample preparation involves mixing urine with water and internal standard (Ro11-9900) followed by centrifugation. Separation of the analytes in the supernatant was achieved using a reversed-phase Spherisorb C6 column (Phenomenex, 5μm, 250 × 4.6 mm i.d.) eluted with methanol-triethylamine-phosphate buffer (pH7.0). Moclobemide and Ro12-5637 were detected by UV absorption at 240 nm. The limits of quantification for moclobemide and Ro12-5637 were 0.5 and 2.0 μg/mL, respectively. This method has been used to measure the concentrations of moclobemide and Ro12-5637 in urine samples from healthy Caucasians administered a 300 mg oral dose of moclobemide.
