Novel bisulphate salts of certain 3-phenyl-3-dimethylaminoalkyl-4,4-dimethylpiperidin-2,6-diones and pharmacologically acceptable solvates thereof are devoid of the weight loss and hepatocyte changes in the rat which limited to marginally effective levels the permitted clinical doses of the corresponding hydrochlorides in the treatment or prophylaxis of stress-related affective disorders such as anxiety, depression, migraine and sleep apnea. The preferred bisulphate salts are 3(3,5-dimethoxyphenyl)-3-(3-dimethylaminopropyl)-4,4-dimethylpiperidine-2,6-dione bisulphate and, especially, 3(3-methoxyphenyl)-3-(3-dimethylaminopropyl)-4,4-dimethylpiperidine-2,6-dione bisulphate.
某些3-苯基-3-二甲基氨基烷基-4,4-二甲基哌啶-2,6-二酮及其药理学上可接受的溶剂化物的新型双硫酸盐,在治疗或预防与压力相关的情感障碍,如焦虑、抑郁、偏头痛和睡眠呼吸暂停等方面,不会出现大鼠体重减轻和肝细胞变化,这限制了相应盐酸的允许临床剂量的边缘有效水平。首选的双硫酸盐是3(3,5-二甲氧基苯基)-3-(3-二甲基氨丙基)-4,4-二甲基哌啶-2,6-二酮双硫酸盐,特别是3(3-甲氧基苯基)-3-(3-二甲基氨丙基)-4,4-二甲基哌啶-2,6-二酮双硫酸盐。
