Patent ID: 7230009

Claim:
A composition comprising a compound of formula VI wherein R 1 is alkyl, alkenyl, in which alkyl or alkenyl can be interrupted by nitrogen, oxygen, or sulfur, and can be substituted at the terminal carbon by hydroxy, alkoxy, alkanoyloxy, alkanoyloxyaryl, alkoxyalkanoyl, alkoxycarbonyl, or dialkylcarbamoyloxy; alkoxy; dialkylamino; alkanoyloxy; alkanoyloxyaryl; alkoxyalkanoyl; alkoxycarbonyl; dialkylcarbamoyloxy; or aryl, in which aryl can be substituted by alkyl, alkoxy, amino, hydroxy, halo, nitro, or alkanoyloxy aryloxy, arylthio, or aralkyl; and R 2 is of the formula wherein R 3 and R 4 are each independently alkyl, alkenyl, cycloalkyl, aryl, or, when R 3 and R 4 are taken together to form a ring with the nitrogen atom, which may optionally be interrupted by a heteroatom, wherein said heteroatom is selected from the group consisting of nitrogen, sulfur, and oxygen, or a pharmaceutically acceptable acid addition salt thereof; an angiotensin converting enzyme inhibitor, pyridoxal phosphate-6-azophenyl-2′,4′-disulphonic acid, or a mixture thereof, wherein said angiotensin converting enzyme inhibitor is selected from the group consisting of: captopril, enalapril, lisinopril, benazapril, fosinopril, quinapril, ramipril, spirapril, imidapril, moexipril, and combinations thereof; and a therapeutically acceptable carrier.
