  Prodrugs of the pyridyl methyl sulfinyl benzimidazole type proton pump inhibitor drugs have a hydrolyzable arylsulfonyl or heteroarylsulfonyl group attached to the benzimidazole nitrogen. The prodrugs of the invention hydrolyze under physiological conditions to provide the proton pump inhibitors with a half life measurable in hours, and are capable of providing sustained plasma concentrations of the proton pump inhibitor drugs for longer time than presently used drugs. The generation of the proton pump inhibitor drugs from the prodrugs of the invention under physiological conditions allows for more effective treatment of several diseases and conditions caused by gastric acid secretion.

  吡啶甲基亚磺酰苯并咪唑类质子泵抑制剂药物的前药具有可水解的芳基磺酰基或杂芳基磺酰基连接到苯并咪唑氮上。本发明的前药在生理条件下水解，可提供半衰期可测量的质子泵抑制剂，并能够提供比目前使用的药物更长时间的持续血浆浓度。在生理条件下从本发明的前药产生质子泵抑制剂药物，可以更有效地治疗由胃酸分泌引起的多种疾病和病况。

  Prodrugs of the pyridyl methyl sulfinyl benzimidazole type proton pump inhibitor drugs have a hydrolyzable sulfinyl or arylsulfonyl group attached to the benzimidazole nitrogen, or include a group that forms a Mannich base with the benzimidazole nitrogen. The prodrugs of the invention hydrolyze under physiological conditions to provide the proton pump inhibitors with a half life measurable in hours, and are capable of providing sustained plasma concentrations of the proton pump inhibitor drugs for longer time than presently used drugs. The generation of the proton pump inhibitor drugs from the prodrugs of the invention under physiological conditions allows for more effective treatment of several diseases and conditions caused by gastric acid secretion.
