6-(p-Acylaminophenyl)-4,5-dihydropyridaz-3-ones of the formula I ##STR1## where R.sup.1 is hydrogen or alkyl of 1 to 3 carbon atoms and R.sup.2, if R.sup.1 is hydrogen, is halogen-substituted alkyl of 3 to 6 carbon atoms or .beta.-haloethyl or, if R.sup.1 is alkyl of 1 to 3 carbon atoms, is halogen-substituted alkyl of 1 to 6 carbon atoms, their manufacture, and therapeutic agents which contain, as the active ingredient, a compound of the formula I, where R.sup.2 may also be halomethyl or .alpha.-haloethyl if R.sup.1 is hydrogen. These compounds may be used as anti-hypertensive agents and for the prophylaxis and therapy of thromboembolic disorders.
化合物I的结构式为:##STR1## 其中R1是氢或1到3个碳原子的烷基,如果R1是氢,则R2是3到6个碳原子的卤代烷基或β-卤代乙基,如果R1是1到3个碳原子的烷基,则R2是1到6个碳原子的卤代烷基。本发明涉及这些化合物的制备方法和含有化合物I作为活性成分的治疗剂,其中如果R1是氢,则R2也可以是卤代甲基或α-卤代乙基。这些化合物可以用作抗高血压剂和预防和治疗血栓栓塞性疾病的药物。
