Zusammenfassung:Pyridopyrimidinetriones of the general formula I in which R denotes a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, R denotes an alkyl group having 1 to 5 carbon atoms, R denotes a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, R denotes a hydrogen atom, a halogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms or a trifluoromethyl group, R denotes a hydrogen atom, a halogen atom, an alkyl group having 1 to 4 carbon atoms or an alkoxy group having 1 to 4 carbon atoms, their N-oxides and their acid addition salts are novel compounds. They have a hypotensive action. Processes for the preparation thereof and of the intermediates are given.
