the effect of alpha-tocopherol nicotinate ( renascin ) , alpha-tocopherol and dodecanoic acid ( lauric acid ) on the positive inotropic action of ouabain and digoxin and on cardiac glycoside induced arrhythmias has been tested in isolated guinea-pig left atria and in anaesthetized guinea-pigs . alpha-tocopherol nicotinate and dodecanoic acid significantly decrease the positive inotropic action of digoxin , but not that of ouabain in isolated guinea-pig atria .
