The effects of administrations of HCI, NH4CI and NH4HCO3 on the excretion of urea and ammonium in man

Abstract
In man, HCl acidosis reduces blood and urinary urea with a concomitant rise in ammonium .**GRAPHIC**. excretion. Significantly less urea is excreted following NH4Cl administration than following equimolar ingestion of NH4HCO3. The results of these alterations in nitrogen excretion are interpreted in terms of HCO3 utilization and production.
