ERADICATING AGENT AND ERADICATION METHOD FOR HELICOBACTER PYLORI

摘要

Disclosed is an eradicating agent for Helicobacter pylori, which comprises an ammonia- or ammonium ion-adsorbent. Also disclosed is an eradication method for H. pylori, which comprises introducing the aforesaid eradicating agent into the stomach infected with H. pylori. H. pylori can survive in the strongly acidic intragastric environment since this bacterium can produce ammonia from urea and thus neutralize gastric acid. According to the aforesaid eradication method, the eradicating agent comprising an ammonia- or ammonium ion-adsorbent (active carbon, silica gel, alumina, zeolite, a cation exchanger, etc.) is introduced into the stomach to adsorb ammonia or ammonium ion. Thus, the intragastric environment is changed so that H. pylori can hardly survive therein, thereby eradicating H. pylori.
