A benzimidazole derivative of formula (1):
(wherein R represents a hydrogen atom or a methoxy group, and n is 0 or 1) or a salt thereof; and a medicament containing the same.
The compounds of the present invention, due to minimized difference in therapeutic effect between subjects, which difference would otherwise be derived from different CYP2C19 activity from subject to subject, ensure that all patients can enjoy proper therapeutic effects at the same dose of the drug. Also, the compounds of the invention have low risk of drug interaction caused by induction of CYP1A family member enzymes, as well as low risk of development of cancer, and thus is useful as a remedy for peptic ulcer, reliably providing therapeutic effects with safety.

(其中R代表氢原子或甲氧基,n为0或1)或其盐;以及含有相同成分的药物。
本发明的化合物可最大程度地减少受试者之间的治疗效果差异(这种差异可能来自于不同受试者的 CYP2C19 活性不同),从而确保所有患者在相同剂量的药物中都能获得适当的治疗效果。此外,本发明化合物因诱导 CYP1A 家族成员酶而引起药物相互作用的风险较低,发生癌症的风险也较低,因此可作为消化性溃疡的治疗药物,在安全的情况下提供可靠的治疗效果。
