Highlights distinct depletion mechanisms in canine hearts; hypothesis-generating and should not inform clinical use.
Does intravenous guanethidine or reserpine alter the release and tissue depletion of norepinephrine from the heart in anesthetized dogs?
Guanethidine and reserpine exhibit different mechanisms of norepinephrine depletion in the heart immediately after administration.
Harrison et al. (1963) studied this question.
