  • Patent number: 4689413
    Abstract: Triazolo-benzodiazepine-1-ethanamines of the formulas ##STR1## where R, R.sub.1, R.sub.2, R.sub.3, R.sub.4 and Ring A are as defined in the specification, e.g., 8-chloro-N,N-dimethyl-.beta.,6-diphenyl-4H-[1,2,4]triazolo[4,3-a][1,4]benz odiazepine-1-ethanamine, and pharmacologically acceptable salts thereof, have been found to have substantial diuretic, natriuretic, but little, if any, kaliuretic activity, which can be used alone, or concomittently with other diuretic drugs such as furosemide or hydrochlorothiazide and/or with antihypertensive agents such as propranolol, captopril, minoxidil, prazosin, guanadrel sulfate, whose actions are supplemented by the action of a diuretic drug.
