  3,6,7,8-substituted-s-triazolo-pyridazine compounds of the formula wherein R3 represents hydrogen or loweralkyl, R6 represents amino, loweralkylamino, diloweralkylamino, heterocyclic amino or lower alkyl substituted heterocyclic amino, wherein the heterocyclic moiety forms a 5, 6 or 7 membered ring, having one or two ring nitrogen atoms and zero or one ring sulfur or oxygen atom; T7 represents loweralkyl; R8 represents hydrogen or loweralkyl; or R7 and R8 taken together represent polymethylene of 3 or 4 methylene units or polymethylene substituted by lower alkyl, or methano or ethano bridges; and their pharmacologically acceptable salts are made by reacting a carboxylic acid with a substituted 3-hydrazino-6-halo-pyridazine and then reacting the resulting 6-halotriazolopyridazine with a corresponding base. The compounds have pharmacological activity as bronchodilators.

  式中，R3代表氢或低碳基，R6代表氨基，低碳基氨基，二低碳基氨基，杂环氨基或低碳基取代的杂环氨基，其中杂环基形成一个5、6或7个成员的环，有一个或两个环氮原子和零或一个环硫或氧原子；T7代表低碳基；R8代表氢或低碳基；或R7和R8一起代表3或4个亚甲基单元的聚甲基或低碳基取代的聚甲基，或甲烷或乙烷桥；它们的药物学可接受盐是由羧酸与取代的3-肼基-6-卤代吡啶嗪反应，然后将得到的6-卤代三唑吡啶与相应的碱反应制得的。这些化合物具有支气管扩张剂的药理活性。
