Compound of general formula (I): ##STR1## in which: X, Y, Z and T each represent, independently of one another, a nitrogen atom, a --CH.dbd. group or a group CW, in which W represents a halogen atom or a lower alkyl or alkoxy group optionally substituted with one or more halogen atoms, such as a trifluoromethyl group, on condition that only one of them represents a nitrogen atom, Ra, Rb, Rc, Rd and Re represent, independently of one another, a hydrogen atom, a halogen atom or a lower alkyl or alkoxy group optionally substituted with one or more halogen atoms, such as a trifluoromethyl group, B represents a hydrogen atom and D a hydroxyl group, or B and D simultaneously represent an oxygen atom, n represents 1 or 2, and R.sub.1 represents a hydrogen atom, a linear or branched lower alkyl, linear or branched lower alkenyl, aryl or lower arylalkyl group or a cycloalkyl group having 3 to 7 carbon atoms, it being possible for each of the lower alkyl, lower alkenyl, aryl, lower arylalkyl and cycloalkyl groups to be substituted with one or more halogen atoms or a lower alkyl or alkoxy group optionally substituted with one or more halogen atoms, such as a trifluoromethyl group, their isomers, epimers and diastereoisomers, and addition salts with a pharmaceutically acceptable acid are useful in the treatment of pain.
通式(I)的化合物:##STR1## 其中:X、Y、Z和T分别独立地表示氮原子、--CH.dbd.基团或CW基团,其中W表示卤素原子或低碳基或低氧基团,可选择地取代一个或多个卤素原子,例如三氟甲基基团,条件是它们中只有一个表示氮原子;Ra、Rb、Rc、Rd和Re分别独立地表示氢原子、卤素原子或低碳基或低氧基团,可选择地取代一个或多个卤素原子,例如三氟甲基基团;B表示氢原子,D表示羟基,或B和D同时表示氧原子;n表示1或2;R.sub.1表示氢原子、线性或支链低碳基、线性或支链低烯基、芳基或低芳基烷基或有3至7个碳原子的环烷基,每个低碳基、低烯基、芳基、低芳基烷基和环烷基都可以用一个或多个卤素原子或可选择地取代一个或多个卤素原子的低碳基或低氧基团,例如三氟甲基基团。它们的异构体、外消旋异构体和对映异构体以及与药学上可接受的酸形成的加合物在疼痛治疗中有用。
