阿尔茨海默型痴呆(Alzheimer disease,以下简称AD),是一种中枢神经系统退行性疾病,是老年期痴呆最常见的一种类型。起病隐袭,病程呈慢性进行性,发病率随年龄增加而增高。临床表现为认知能力下降、精神行为异常、日常生活能力降低等。研究发现,AD发病机制与中枢胆碱能损伤和兴奋性氨基酸毒性有关。目前,国内外批准用于阿尔茨海默病治疗的药物主要有胆碱酯酶抑制剂和谷氨酸受体拮抗剂两类。

国家食品药品监督管理总局已批准用于治疗AD的药物主要是胆碱酯酶抑制剂。包括盐酸多奈哌齐片、石杉碱甲胶囊、氢溴酸加兰他敏片、重酒石酸卡巴拉汀胶囊等。盐酸美金刚是谷氨酸受体拮抗剂,可以阻断谷氨酸浓度病理性升高导致的神经元损伤,主要用于中重度AD患者。由于作用机制不同,盐酸美金刚可与胆碱酯酶抑制剂合用,增加疗效。

该药品目前已在德国、美国等国家上市。我国于2006年9月批准国外制药公司的盐酸美金刚片进口。此次国家食品药品监督管理总局批准的珠海联邦制药股份有限公司生产的盐酸美金刚口服溶液(120ml:240mg)是3.1类新药,盐酸美金刚片(10mg)是国内首家盐酸美金刚仿制药,均经生物等效性试验证明与参比制剂具有生物等效性。同时还批准了该公司的原料药新药生产,实现了从原料药到制剂的国产化。

国家食品药品监督管理总局批准盐酸美金刚的说明书,包括使用说明和服用该药物的潜在风险信息。对于中重度肾功能不全患者,美金刚应减量。对于癫痫患者、有惊厥病史、或癫痫乙肝体质患者使用美金刚时应慎重。妊娠期不应服用,哺乳期服用应停止哺乳。

J Alzheimers Dis:保持口腔卫生可远离痴呆

保持口腔卫生不只对牙齿健康有好处。英国一项新研究发现,口腔内一种与牙龈疾病有关的细菌会增加早老性痴呆症(阿尔茨海默病)的风险。 英国中兰开夏大学等机构的研究人员在新一期《阿尔茨海默病杂志》上报告说,他们对比了20名死者的脑组织,这其中有10人患有阿尔茨海默氏症。结果发现,阿尔茨海默氏症患者脑中一种细菌的含量远高于普通人。 这种细菌名为“牙龈卟啉单胞菌”,是引发牙周病的一种主要细菌。此前研究已发

JAD:体育锻炼可逆转轻度认知障碍患者的记忆功能

美国一项研究显示,老年轻度认知障碍(MCI)患者在跑步机上走步30分钟/天, 4天/周,坚持12周,可改善其记忆得分和神经效率。研究表明了锻炼可抑制或延迟危险人群向阿尔茨海默病(AD)转变。相关论文在线发表于《阿尔茨海默病杂志》(Journal of Alzheimer's Disease)。 研究者招募了年龄在60—88岁的社区老年居民,他们每周从事<3

AAIC 2013:阿尔茨海默病研究进展

在波士顿召开的2013年阿尔茨海默氏症协会国际会议(Alzheimer's Association International Conference 2013),公布了有关阿尔茨海默氏症和老年痴呆症的新研究结果,包括新型疗法和预防方法、可能存在的新的风险因素、早期发现和诊断上的进步以及病情恶化的 最新模型。 多数类型的癌症与更低的阿尔茨海默氏症风险有关;化疗可降低阿尔茨海默氏症风险
