The invention relates to 1,2,4-triazolo [4,3-b]pyridazines substituted in the 7-position of formula: ##STR1## in which R represents hydrogen, a lower alkyl group, a phenyl group, a chlorophenyl group or a benzyl group and R.sub.1 represents a phenyl, halogenophenyl, trifluoromethylphenyl, lower alkyl-phenyl or lower alkoxy-phenyl group or a phenyl-lower alkyl group, or one of its pharmaceutically acceptable salts. Said compounds antagonize the effects of benzodiazepines and therefore are useful as antidotes in the abuse of benzodiazepines and compounds acting on benzodiazepine receptors.
本发明涉及在式中7位被取代的1,2,4-三唑并[4,3-b]吡啶衍生物:##STR1## 其中R代表氢、较低的烷基、苯基、氯苯基或苄基,R.sub.1代表苯基、卤代苯基、三氟甲基苯基、较低的烷基苯基或较低的烷氧基苯基或苯基较低的烷基,或其药学上可接受的盐。所述化合物拮抗苯二氮平的作用,因此在对苯二氮平和作用于苯二氮平受体的化合物的滥用中有用作为解毒剂。
