The present invention relates to new salts of the single enantiomers of omeprazole, i.e. salts of (S)-5-methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridinyl)-methyl]sulfinyl]-1H-benzimidazole ((S)-omeprazole) and (R)-5-methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridinyl)-methyl]sulfinyl]-1H-benzimidazole ((R)-omeprazole) respectively. More specifically, the present invention relates to 1-cyclohexylethyl ammonium salts of the compounds, formed by a reaction of (S)-omeprazole and (R)-omeprazole respectively and 1-cyclohexylethyl amine. The present invention also relates to a process for preparing the compounds of the invention, a pharmaceutical preparation and a method for treatment of gastric related disorders by administering the compounds of the invention.
本发明涉及奥美拉唑单对映体的新盐,即(S)-5-甲氧基-2-[[(4-甲氧基-3,5-二甲基-2-吡啶基)-甲基]亚磺酰基]-1H-苯并咪唑((S)-奥美拉唑)和(R)-5-甲氧基-2-[[(4-甲氧基-3,5-二甲基-2-吡啶基)-甲基]亚磺酰基]-1H-苯并咪唑((R)-奥美拉唑)的盐。更具体地,本发明涉及化合物的1-环己基乙基铵盐,由(S)-奥美拉唑和(R)-奥美拉唑分别与1-环己基乙基胺反应形成。本发明还涉及制备本发明化合物的方法、制药制剂以及通过给予本发明化合物治疗胃相关疾病的方法。
