| titleOfInvention | 4(or 3)-(3,4-dihydroxyphenyl)pyridines, their preparation and use as cardiotonics |
| abstract | ABSTRACT OF THE DISCLOSURE 4(or 3)-(3,4-Dihydroxyphenyl)pyridine, a cardiotonic agent, is prepared by demethylating 4(or 3)-13,4-dimethoxy-phenyl)pyridine, preferably by heating with aqueous hydrogen bromide. 4(or 3)-[3,4-dihydroxyphenyl]pyridine, or pharmaceutically-acceptable acid-addition salt thereof is disclosed as the active component in a cardiotonic composition for increasing cardiac contractility and in the method for increasing cardiac contractility in a patient requiring such treatment. The novel isomeric 2-[3,4-dihydroxyphenyl]pyridine is shown for comparative purposes. |
