Abstract
The invention provides novel hydrazine derivatives of the formula: ##STR1## in which R is a variously substituted oxy or thio substituted phenyl radical, 2-oxobenzimidazol-5-yl radical or 3-pyridyl radical; PA1 R' is a radical of formula: ##STR2## in which R.sub.5 and R.sub.6 taken separately are each hydrogen, and taken together form, with the nitrogen atoms to which they are attached, an imidazolinyl radical of formula; ##STR3## and R" is hydrogen or lower alkyl, and the pharmaceutically acceptable addition salts, with non-toxic acids, of these hydrazine derivatives. These compounds are useful as anti-hypertensive agents.
