Acetazolamide (10 mg/kg, intraperitoneally) increases the urinary excretion of cesium-137 in the rat. Meralluride (6.8 mg of Hg per kilogram, subcutaneously) blocks the effect of acetazolamide on the cesium-137 excretion without any influence on the urine volume and pH of the urine. This indicates that acetazolamide increases the urinary excretion of cesium-137 by increasing its secretion through the renal tubule in the same manner as it increases the excretion of potassium and rubidium-86.
