Abstract

There are presented novel benzodiazepine derivatives of the formula ##STR1## wherein R.sup.1 is lower alkyl, lower hydroxyalkyl or lower dialkylaminoalkyl, R.sup.2 and R.sup.3 each are lower alkyl, R.sup.4 is halogen, R.sup.5, R.sup.7 and R.sup.8 each are hydrogen or halogen and R.sup.6 is nitro, amino, lower alkylamino, lower dialkylamino or a group of the formula H.sub.2 N--C(CH.sub.3).sub.2 --CO--NH--, R.sup.9 R.sup.10 N--CO--NH-- or ##STR2## and either R.sup.9 is hydrogen or lower alkyl and R.sup.10 is lower alkyl or lower hydroxyalkyl or R.sup.9 and R.sup.10 together with the nitrogen atom are a 3- to 7-membered heterocycle which, provided it is at least 5-membered, can contain as a ring member an oxygen or sulfur atom or a group of the formula >N--R in which R is hydrogen or lower alkyl, and their pharmaceutically acceptable acid addition salts. The compounds possess aldosterone-antagonistic properties and are accordingly suitable for the control or prevention of heart failure, hepatic ascites, primary aldosteronism and idiopathic hypertension.
