| Abstract: | Long-term normal-dose benzodiazepine treatment in seven patients was associated with reduced urinary excretion of MOPEG (4-hydroxy-3-methoxy-phenylglycol). Following the discontinuation of the drugs a characteristic withdrawal reaction occurred, with an increase towards normal values of the MOPEG excretion levels and changes in the excretion of 5-HIAA (5-hydroxyindoleacetic acid). No significant changes in the 24-hr urinary excretion of free cortisol or HMMA (3-methoxy-hydroxy-mandelic acid) were detected. |
