Why the study?
Does fenoldopam differ from sodium nitroprusside in its effects on hemodynamics and sympathetic outflow in neuraxis-intact and baro-denervated animal models?
Does fenoldopam differ from sodium nitroprusside in its effects on hemodynamics and sympathetic outflow in neuraxis-intact and baro-denervated animal models?
Fenoldopam attenuates cardiac and sympathetic baroreflex sensitivity compared to sodium nitroprusside, which may explain its lack of rebound hypertension, though its hypotensive effect has a slower offset.

Hypothesis-generating for vasodilator baroreflex differences in intact models; human studies needed before clinical relevance.
Yakazu et al. (2001) studied this question.
