Differential inotropic actions of ethmozine and ethacizin (diethylamine analog of ethmozine)

Abstract The direct inotropic actions of ethmozine and of its diethylamine analog, ethacizin, were studied in the presence of muscarinic and beta-adrenoreceptor blockade in 12 ferret right ventricular papillary muscles. In each muscle ethmozine caused a small but consistent and significant ( p p
