Renin release after furosemide and ethacrynic acid in man. Evidence for neural reflex control mechanisms.
The mechanisms of renin release after furosemide (F) and ethacrynic acid (EA) in man were examined. We evaluated whether acute volume shifts within the low pressure system after F induce renin release via neural pathways. Immersion in a water-bath or beta-blockade reduced the increase of plasma renin concentration after F but not after EA. It is concluded that acute renin release after F but not after EA in man is partially due to neurally mediated reflexes originating from volume receptors in the cardiopulmonary area.
