Methods and compositions of the invention employ acetylcholinesterase (ACE) inhibitors to prevent and treat diseases and other disorders of the central nervous system (CNS), including Alzheimer's disease. ACE inhibitors are administered for targeted delivery to the CNS, for example by intranasal delivery. The methods and compositions of the present invention yield therapeutic concentrations of ACE inhibitors in a CNS tissue or compartment without the attendant disadvantages, risks and side effects of oral or injection delivery. Exemplary ACE inhibitors for use within the invention include galantamine and various salts and derivatives of galantamine. Carboxylate salts of galantamine (e.g., galantamine gluconate, galantamine lactate, galantamine citrate and galantamine glucarate) described herein exhibit a significant increase in solubility compared to other forms of galantamine, such as galantamine hydrobromide.
本发明的方法和组合物采用
乙酰胆碱酯酶(ACE)
抑制剂来预防和治疗中枢神经系统(CNS)的疾病和其他失调,包括阿尔茨海默病。
乙酰胆碱酯酶抑制剂可定向递送至中枢神经系统,例如通过鼻内递送。本发明的方法和组合物能在中枢神经系统组织或区块中产生治疗浓度的 ACE

氢溴酸加兰他敏)相比,本文所述的
加兰他敏羧酸盐(如
葡萄糖酸
加兰他敏、
乳酸加兰他敏、
柠檬酸加兰他敏和
葡萄糖酸
加兰他敏)的溶解度显著增加。
