Patients susceptible to or suffering from conditions and disorders, such as central nervous system disorders, are treated by administering to a patient in need thereof compositions that are hydroxybenzoate salts of E-metanicotine-type compounds. The formation of hydroxybenzoate salts of the E-metanicotine compounds is also useful in purifying the E-metanicotine compounds, as the hydroxybenzoate salts tend to crystallize out, leaving impurities such as Z-metanicotine compounds, and compounds where the double bond has migrated, in solution. If desired, the hydroxybenzoate salts can be converted to either the free base (the E-metanicotine) or to another pharmaceutically acceptable salt form.
对于易感受或患有中枢神经系统疾病等疾病和疾病的患者,可以通过向需要治疗的患者施用羟基
苯甲酸酯盐的E-甲
烟碱型化合物来进行治疗。羟基
苯甲酸酯盐的形成对于纯化E-甲
烟碱化合物也是有用的,因为羟基
苯甲酸酯盐往往会结晶出来,留下杂质,例如Z-甲
烟碱化合物和双键迁移的化合物。如果需要,羟基
苯甲酸酯盐可以转化为自由碱基(E-甲
烟碱)或其他药学上可接受的盐形式。
