The present invention relates to an antidepressant containing as an active ingredient a xanthine derivative or a pharmaceutically acceptable salt thereof, the xanthine derivative being represented by Formula (I) : ##STR1## in which R.sup.1, R.sup.2, and R.sup.3 represent independently hydrogen, lower alkyl, lower alkenyl; R.sup.4 represents cycloalkyl, --(CH.sub.2).sub.n --R.sup.5 (in which R.sup.5 represents substituted or unsubstituted aryl or a substituted or unsubstituted heterocyclic group; and n is an integer of 0 to 4), or ##STR2## (in which Y.sup.1 and Y.sup.2 represent independently hydrogen, halogen or lower alkyl; and Z represents substituted or unsubstituted aryl, ##STR3## (in which R.sup.6 represents hydrogen, hydroxy, lower alkyl, lower alkoxy, halogen, nitro, or amino; and m represents an integer of 1 to 3), or a substituted or unsubstituted heterocyclic group); and X.sup.1 and X.sup.2 represent independently O or S.
本发明涉及一种含有黄嘌呤衍生物或其药用可接受盐作为活性成分的抗抑郁药,黄嘌呤衍生物由公式(I)表示:##STR1## 其中,R.sup.1、R.sup.2和R.sup.3独立地代表氢、低级烷基、低级烯基;R.sup.4代表环烷基,--(CH.sub.2).sub.n --R.sup.5(其中R.sup.5代表取代或未取代的芳基或取代或未取代的杂环族;n是0到4的整数),或##STR2## (其中Y.sup.1和Y.sup.2独立地代表氢、卤素或低级烷基;Z代表取代或未取代的芳基,##STR3## (其中R.sup.6代表氢、羟基、低级烷基、低级烷氧基、卤素、硝基或氨基;m是1到3的整数),或取代或未取代的杂环族);X.sup.1和X.sup.2独立地代表O或S。
