The influence of the alpha adrenergic blocking drugs phenoxybenzamine, phentolamine, chlorpromazine and dihydroergotamine on the positive inotropic effect of adrenergic stimuli in mammalian hearts was re-evaluated. No evidence was found to support the contention that these drugs possess selective cardiac adrenergic blocking properties.
