Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
76 words
A method for alleviating angiotensin related hypertension in hypertensive mammals which comprises administering an effective dose of an angiotensin converting enzyme inhibitor having the formula ##STR8## or salt thereof, wherein R 1 is hydrogen, lower alkyl, phenyllower alkylene, hydroxy-lower alkylene, hydroxyphenyl-lower alkylene or guanidinolower alkylene; R 2 , R 3 and R 4 each is hydrogen, lower alkyl or phenyl-lower alkylene; R 5 is hydrogen, lower alkanoyl, benzoyl or ##STR9## n is 0, 1 or 2.
Claim 2
Independent Claim
76 words
A method for alleviating angiotensin related hypertension in hypertensive mammals which comprises administering an effective dose of an angiotensin converting enzyme inhibitor having the formula ##STR8## or salt thereof, wherein R 1 is hydrogen, lower alkyl, phenyllower alkylene, hydroxy-lower alkylene, hydroxyphenyl-lower alkylene or guanidinolower alkylene; R 2 , R 3 and R 4 each is hydrogen, lower alkyl or phenyl-lower alkylene; R 5 is hydrogen, lower alkanoyl, benzoyl or ##STR9## n is 0, 1 or 2.
