Abstract

4-Alkoxy-pyrido[2,3-d]pyrimidine derivatives are described as well as processes for their preparation. For reason of their vasospasmolytic effects these compounds are mainly indicated for the treatment of cerebral, cardiac, and peripheral vascular diseases such as myocardiac ischemia, cerebral infarction, pulmonary thromboses, as well as in cases of arteriosclerosis and other stenotic disorders. They are therefore valuable agents for combating cardiovascular mortality.
