Psychotropic drug sales data for Italy were examined for the years 1975-84. The principal findings were of more-or-less consistent annual increases in sales of antidepressants, minor tranquillizers and, to a lesser extent, of neuroleptics. These trends are interpreted in the context of the characteristics of the Italian National Health Service (NHS), and in relation to findings from psychotropic drug utilization studies in other Western countries. Regional differences in psychotropic drug sales for 1983/4 were also examined. Marked differences were found and, in general, levels of use were higher in North/Central Italy than in the South. Factors influencing regional differences were explored using regression analysis. Regional NHS expenditure (excluding that on drugs) was found to influence strongly the sales of all categories of psychotropic drug, whereas there was also a marked urban greater than rural difference in the sales of tranquillizers.
对1975年至1984年意大利精神药物的销售数据进行了研究。主要研究结果显示，抗抑郁药、轻度镇静剂以及在较小程度上的抗精神病药的销售额大致呈逐年增长趋势。这些趋势是结合意大利国家医疗服务体系（NHS）的特点以及其他西方国家精神药物使用研究的结果来进行解读的。同时也对1983/4年度精神药物销售的地区差异进行了研究。结果发现存在显著差异，总体而言，意大利北部/中部的使用水平高于南部。使用回归分析探究了影响地区差异的因素。结果发现，地区NHS支出（不包括药品支出）对各类精神药物的销售有强烈影响，而镇静剂的销售也存在明显的城市高于农村的差异。
