Abstract
Studies on the absorption and excretion of CHS-Na in rabbit and human are reported in this paper. The urinary excretion rate of CHS-Na was determined after oral administration to rabbit, and the absorption rate was calculated from the excretion data. And the absorption of CHS-Na was studied after oral administration with the compounds such as caffeine, theophylline, theobromine, albumin, casein, and citric acid, and it was suggested that the absorption of CHS-Na was accelerated in the presence of caffeine and citric acid.
