Key result
Prazosin lowered vascular resistance and reduced vasoconstrictor responses to noradrenaline via a peripheral sympatholytic effect, with no central action on blood pressure demonstrated.

Prazosin's peripheral sympatholytic profile in rat models merits clinical investigation; leaves open confirmation in human hypertension.
Does prazosin reduce vascular resistance and vasoconstrictor responses in normotensive and genetically hypertensive rats?
Prazosin acts as a potent peripheral sympatholytic agent that lowers vascular resistance without direct vasodilatory or central blood pressure-lowering effects in rat models.
Wood et al. (1975) studied Normotensive and genetically hypertensive rats. Prazosin vs. Phentolamine / Baseline was evaluated on Cardiovascular effects (vascular resistance and vasoconstrictor responses). Prazosin lowered vascular resistance and reduced vasoconstrictor responses to noradrenaline via a peripheral sympatholytic effect, with no central action on blood pressure demonstrated.
