4-(3,4-Diaminophenyl)pyridine or salts, and use thereof as cardiotonic |
| abstract |
4-(3,4-Diaminophenyl)pyridine, a cardiotonic agent, is prepared by reducing 4-(4-amino-3-nitrophenyl)pyridine or preferably by reacting 4-(4-acetylamino-3-nitrophenyl)pyridine or 4-(3-acetylamino-4-nitrophenyl)pyridine with stannous chloride and hydrochloric acid. 4-(3,4-diaminophenyl)pyridine or pharmaceutically-acceptable acid-addition salt thereof is disclosed as the active ingredient in a cardiotonic composition for increasing cardiac contractility and in the method for increasing cardiac contractility in a patient requiring such treatment. |
