4-Oxo-pyrido[2,3-d]pyrimidine derivatives are herein described as well as processes for their preparation. These compounds possess valuable pharmacological properties. As calcium antagonists they exert vasospasmolytic, vasodilatory, and antihypertensive activities. Surprisingly some of the compounds also have the effect of increasing contractility. They are therefore particularly suited for the treatment of vascular diseases.
