[Effect of dopamine and its combination with furosemide on sodium transport in the rat kidney].

In experiments on rats phentolamine, propranolol, indomethacin were shown to exert no significant effect on the natriuretic action of dopamine, whereas haloperidol completely prevented it. In rats with chronic narrowing of the vena cava dopamine potentiated the diuretic and natriuretic effects of furosemide.
