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 compound) or to another pharmaceutically acceptable salt form.
易感受或患有中枢神经系统疾病等疾病和疾病的患者,通过给需要治疗的患者施用羟基苯甲酸盐型E-甲烟碱类化合物的组合物来治疗。形成羟基苯甲酸盐的E-甲烟碱化合物也有助于纯化E-甲烟碱化合物,因为羟基苯甲酸盐倾向于结晶出来,留下杂质,例如Z-甲烟碱化合物和双键迁移的化合物在溶液中。如有需要,羟基苯甲酸盐可转化为自由碱(E-甲烟碱化合物)或另一种药学上可接受的盐形式。
