Novel 5-acyl-2-(1H)pyridinones and their use as cardiotonic agents. Typical of the compounds is 5-acetyl-1,2-dihydro-6-methyl-2-oxo-3-pyridinecarbonitrile which is prepared by condensing anionic cyano acetamide with 3-[(dimethylamino)methylenyl]-2,4-pentanedione in an inert organic solvent.
Novel 3-carboxy- and 3-carbalkoxy-5-benzoyl-2(1H)-pyridinones as well as the pharmaeutically acceptable salts thereof are cardiotonic agents useful in the treatment of heart failure.
