Biochem/physiol Actions

Ammonium chloride is a component of the nitrogen cycle. Excess of ammonium chloride depletes ATP in astrocytes. Ammonium chloride inhibits the acidification in endosome-lysosome system. It is a hemolysing agent used in the lysis of erythrocytes. Ammonium chloride administration promotes creatinine and urea clearance in rat.
