    • New benzopyrrolidinone compounds, which can be used as medicaments and correspond to the formula ##STR1## in which: either: R.sub.1 and R.sub.2 together represent, with the bond of the etherocycle to which they are attached, an optionally substituted benzene nucleus and, simultaneously, R.sub.3 and R.sub.4 are hydrogen, (C.sub.1 -C.sub.4)alkyl or (C.sub.5 -C.sub.6)cycloalkyl;or:R.sub.1 is hydrogen, R.sub.4 is a single bond and R.sub.2 and R.sub.3 together represent, with the bond of the heterocycle to which they are bonded, an optionally substituted benzene nucleus; andA is a straight or branched hydrocarbon chain having from 2 to 6 carbon atoms that is optionally substituted by hydroxy;X is a single bond, oxygen or sulphur; andY is hydrogen, halogen or (C.sub.1 -C.sub.5)alkyl or alkoxy.These new compounds and the physiologically tolerable salts thereof can be used therapeutically, especially in the treatment of bronchospastic disorders and inflammations in the ENT area.
    • 新的苯并吡咯烷酮化合物,其可以用作药物并且对应于式“IMAGE”,其中:R 1和R 2一起表示与它们所连接的醚基的键,任选取代的苯核, R3和R4是氢,(C1-C4)烷基或(C5-C6)环烷基; 或:R 1是氢,R 4是单键,并且R 2和R 3一起表示与它们所键合的杂环的键,任选取代的苯核; 并且A是具有2-6个碳原子的直链或支链烃链,任选被羟基取代; X是单键,氧或硫; 和Y是氢,卤素或(C 1 -C 5)烷基或烷氧基。 这些新化合物及其生理上可耐受的盐可用于治疗,特别是在ENT区域的支气管痉挛性障碍和炎症的治疗中。
