Abstract
Abstract This invention concerns anti-hypertensive compositions and a method of lowering blood pressure in mammals. The active component of the compositions is a compound of the formula: <IMAGE> I wherein R1 and R2 are independently chosen from straight chain and branched chain C1-C12 alkyl groups and benzyl, with the proviso that no branch occur on the alpha carbon atom of the alkyl groups; or R1 and R2 together with the nitrogen atom they are bonded to form a pyrrolidino, piperidino, piperazino or morpholino group, M+is a pharmaceutically acceptable cation, wherein X is the valence of the cation.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
84 words
A sterile pharmaceutical composition useful in the treatment of hypertension comprising: an effective amount of a compound of the formula ##STR5## wherein R 1 and R 2 are independently selected from the group consisting of a straight chain or branched chain C 1 -C 12 alkyl group and a benzyl group, with the proviso that no branch occur on the alpha carbon atom, M +X is a pharmaceutically acceptable cation, wherein x is the valence of the cation; and a pharmaceutically acceptable carrier therefor.
Claim 2
Dependent Claim
84 words
A sterile pharmaceutical composition useful in the treatment of hypertension comprising: an effective amount of a compound of the formula ##STR5## wherein R 1 and R 2 are independently selected from the group consisting of a straight chain or branched chain C 1 -C 12 alkyl group and a benzyl group, with the proviso that no branch occur on the alpha carbon atom, M +X is a pharmaceutically acceptable cation, wherein x is the valence of the cation; and a pharmaceutically acceptable carrier therefor.
