Novel derivatives of thienylacetic acid amides of the general formula ##STR1## in which the two nitrogens on the cyclohexane ring are transconnected, the basic acetic acid amide radical is in position 2 or 3 of the thiophene nucleus, R is C.sub.1 -C.sub.3 alkyl, R.sub.1 and R.sub.2 are independently C.sub.1 -C.sub.3 -alkyl or represent together with the nitrogen atom to which they are attached a pyrrolidine or piperidine ring and X and Y are independently hydrogen, chlorine or bromine in position 2 to 5 of the thiophene nucleus in dependence on the position of the basic acetic acid amide group, and their pharmaceutically acceptable acid addition salts are .mu.-specific analgetics, which do not cause any physical dependence. Therefore, they are suitable for protracted treatment of pain conditions.
通式为##STR1##的噻吩乙酸酰胺的新衍生物,其中环己烷环上的两个氮原子是反式连接的,基本的乙酸酰胺基团位于噻吩环的2或3位置,R为C.sub.1-C.sub.3烷基,R.sub.1和R.sub.2独立地为C.sub.1-C.sub.3烷基,或者与它们所连接的氮原子一起形成吡咯烷或哌嗪环,X和Y在噻吩环的2至5位置上独立地为氢、氯或溴,取决于基本的乙酸酰胺基团的位置,它们的药学上可接受的酸盐是.μ.特异性镇痛剂,不会引起任何身体依赖性。因此,它们适用于长期治疗疼痛症状。
