    Abstract:
    The effects of alprazolam (1.5 mg/die) on the levels of the monoaminergic neurotransmitter metabolites, on the activity of the hypothalamic-pituitary-adrenal axis and on clinical outcome in subjects with primary late-onset dysthymia were investigated. Drug treatment significantly decreased plasma and urinary cortisol levels, serotonin platelet-bound and urinary 3-methoxy-4-hydroxyphenylglycol concentrations, while it increased plasma homovanillic acid (HVA) concentrations. Significant relationships were observed between neurochemicals and global scores or some items of the Hamilton Depression Rating Scale, before and after treatment. Patients responded positively (73%) to the therapy; clinical outcome was significantly correlated with plasma and urinary HVA levels. Collected data seem to support the hypothesis that central monoaminergic systems are in part involved in therapeutic response to alprazolam.
