A pharmaceutical preparation for ameliorating digestive system-related symptoms is provided. The present invention uses an aminobenzamide compound represented by the following formula (1) or a salt thereof:
wherein each of R¹ and R² is independently a lower alkoxyl group; R³ is a hydrogen atom, a lower acyl group, a lower alkyl group, a lower alkoxycarbonyl group or a group represented by a formula -X-SO₃M where X is a lower alkylene group and M is an alkali metal or an alkaline earth metal; R⁴ is a hydrogen atom, a halogen atom or a lower alkoxyl group; R⁵ is an amino group, a morpholino group or a lower alkylamino group, where the alkyl moiety of the lower alkylamino group may have a hydroxyl group; and n is an integer of 1 to 6.
本发明提供了一种用于改善消化系统相关症状的药物制剂。本发明使用由下式(1)代表的
氨基苯甲酰胺化合物或其盐:
其中R¹和R²各自独立地为低级烷氧基;R³为氢原子、低级酰基、低级烷基、低级烷氧羰基或由式-X-SO₃M代表的基团,其中X为低级亚烷基,M为碱
金属或碱土
金属;R⁴ 是氢原子、卤素原子或低级烷氧基; R⁵ 是
氨基、吗啉基或低级烷基
氨基,其中低级烷基
氨基的烷基可带有羟基;以及 n 是 1 至 6 的整数。
