After simulation of artificial gastric juice and intestinal fluid in vivo, the changes of the adsorption rates of norfloxacin by Na-montmorillonite at the different PH were measured. The modification of Na-montmorillonite can adsorb Norfloxacin. It reduced the dissolution of norfloxacin. And the concentration of norfloxacin decreased. The effect of the adsorption norfloxacin by Na-montmorillonite was very strong at the different PH. Therefore, it must be avoided to administer the two drugs simultaneously. Keyword: modification of Na-montmorillonite; norfloxacin; adsorption; PH 目 录
