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.
易感受或患有中枢神经系统疾病等病症的患者,可通过给予含羟基
苯甲酸盐的E-甲
烟碱类化合物组成的药物来进行治疗。形成E-甲
烟碱羟基
苯甲酸盐也可用于纯化E-甲
烟碱化合物,因为羟基
苯甲酸盐易于结晶,从而留下溶液中的杂质,如Z-甲
烟碱化合物和双键迁移的化合物。如果需要,羟基
苯甲酸盐可以转化为自由碱基(E-甲
烟碱)或其他药用可接受的盐形式。
