The present invention relates to a medicine which comprises a compound (I) of the formula:
[wherein the ring M is a heterocylic ring having -N=C<, -CO-N< or -CS-N< as a partial structure ―X=Y〈,
Ra and Rb are bound to each other to form the ring A, or they are the same or different each representing a hydrogen atom or a substituent on the ring M;
the rings A and B each is an optionally substituted homocycle or heterocycle, and at least one of them is an optionally substituted heterocycle;
the ring C is an optionally substituted homocycle or heterocycle;
the ring Z is an optionally substituted nitrogen-containing heterocycle; and
n is an integer of 1 to 6]
or a salt thereof in combination with a drug having an emetic action.
The compounds (I) or their salts are useful as anti-emetic drugs. Particularly, vomiting caused by drugs having an emetic action can be inhibited by these compounds rapidly and safely at a low dose.
本发明涉及一种药物,该药物由式(I)化合物组成:
[其中环 M 是杂环,具有-N=C〈、-CO-N〈或-CS-N〈作为部分结构-X=Y〈、
Ra 和 Rb 相互结合形成环 A,或者它们相同或不同,各自代表环 M 上的一个氢原子或一个取代基;
环 A 和环 B 各自是任选取代的均环或杂环,其中至少一个是任选取代的杂环;
环 C 是任选取代的均环或杂环
环 Z 是任选取代的含氮杂环;以及
n 是 1 至 6 的整数]
或其盐与具有催吐作用的药物结合使用。
化合物 (I) 或其盐类可用作止吐药。特别是,具有催吐作用的药物引起的呕吐,可以通过这些化合物以低剂量快速安全地抑制。
