摘要

The invention concerns urea and carbamic acid derivatives of the general formula (R1NR2)-A-R3 (I), in which A and R1 to R3 are defined as in claim 1. The invention further concerns their tautomers and stereoisomers including their mixtures and salts, in particular their physiologically compatible salts with inorganic or organic acids or bases which have valuable pharmacological properties, preferably aggregation-inhibiting effects. Finally, the invention concerns drugs containing these compounds, their use and a process for their preparation.
