Compounds of the formula I: ##STR1## in which R represents a hydrogen atom or an alkyl radical containing from 1 to 8 carbon atoms and R.sub.1 and R.sub.2, which may be identical or different independently represent a hydrogen atom, an alkyl radical containing from 1 to 4 carbon atoms, a --CONH.sub.2 radical, a --CO.sub.2 alk.sub.1 radical in which alk.sub.1 represents an alkyl radical containing from 2 to 8 carbon atoms, or an--SO.sub.2 alk.sub.2 radical in which alk.sub.2 represents an alkyl radical containing from 1 to 8 carbon atoms, or R.sub.1 and R.sub.2 together with the nitrogen atom form a heterocycle provided that R.sub.1 and R.sub.2 are not both hydrogen, as well as the alkali metal, alkaline earth metal, ammonium or amine salts of compounds of formula I in which R represents a hydrogen atom. These compounds are useful in treating hyperchlorhydria, gastric or gastroduodenal ulcers, gastritis, hiatal hernias and gastric or gastroduodenal ailments accompanied by gastric hyperacidity. The invention includes pharmaceutical compositions comprising compounds of formula (I) as well as methods of making the compounds.
公式I的化合物:##STR1##,其中R代表氢原子或含有1至8个碳原子的烷基基团,R.sub.1和R.sub.2,可以独立相同或不同地代表氢原子、含有1至4个碳原子的烷基基团、--CONH.sub.2基团、--CO.sub.2 alk.sub.1基团,其中alk.sub.1代表含有2至8个碳原子的烷基基团,或--SO.sub.2 alk.sub.2基团,其中alk.sub.2代表含有1至8个碳原子的烷基基团,或者R.sub.1和R.sub.2与氮原子一起形成一个杂环,前提是R.sub.1和R.sub.2不都是氢,以及碱金属、碱土金属、铵盐或化合物的胺盐公式I,其中R代表氢原子。这些化合物在治疗高氯酸、胃溃疡、胃炎、食管裂孔疝和胃或胃十二指肠疾病伴随胃酸过多方面是有用的。该发明包括包含公式(I)化合物的药物组合物以及制备这些化合物的方法。
