Substituted 6-phenyl-3(2H)-pyridazinone compounds are useful as cardiotonic agents. Said compounds cause a significant increase in myocardial contractility in the anesthetized dog. Said compounds are produced by reacting substituted γ-oxobenzenebutanoic acids with suitably substituted hydrazines to provide 6-phenyl-4,5-dihydro-3(2H)-pyridazinones which are dehydrogenated to the desired product. The intermediate 6-phenyl-4,5-dihydro-3(2H)-pyridazinones are themselves useful as cardiotonic agents.
