Product Details
羧甲淀粉钠(SSG)
包装规格:25千克/袋 25千克/桶
质量标准:CP2020 USP现行版
主要用途:
羧甲淀粉钠系淀粉的衍生物,羧甲淀粉钠主要用作固体制剂的崩解剂。通过快速吸水达到快速而显著的溶胀,从而起到崩解作用,同时具有可压性,可改善片剂的成型性,增加片剂的硬度而不影响其崩解性,一般用量为2%-8%。
羧甲淀粉钠可以使机体的细胞增多;选择性推进T 细胞,推进T 细胞成熟分化;推进lymph母细胞转化,提高lymph细胞计数;提高血浆IgA、IgG 浓度,从而提高机体抵抗力,减少患儿反复上呼吸道病的发作次数和病程,减少呼吸道病对小儿健康和成长的危害。同时还可以降低血浆中IgM 含量,降低嗜碱粒细胞含量,减少嗜碱粒细胞表面的受体和IgE 结合所产生与呼吸道病发病有关的致敏反应。从而亦减少由小儿反复上呼吸道病诱发的支气管病。所以羧甲淀粉钠的溶液为刺激剂,可以激发细胞的生命力,提高抗体水平,增加抵抗力。
羧甲淀粉钠系淀粉的衍生物,用量一般为百分之2-8,具有非常好的可压性和流动性,便于全粉末或胶囊粉末灌装。羧甲淀粉钠崩解性能好,可吸水快速膨胀,片剂加入本品可迅速吸水崩解,大大缩短了崩解时限。尤其适用于制备水不溶性的药品。羧甲淀粉钠主要用做片剂、胶囊剂、颗粒剂、丸剂的崩解剂及液体制剂的助悬剂,可内加、外加或内外加。羧甲淀粉钠粘度适中,可用冷水制浆,既可提高片剂硬度,又不影响崩解度,提高了药品的溶出度和生物利用度,羧甲淀粉钠还具有良好的吸水膨胀性和可压性,可改进片剂的成型性,增加片剂的硬度而不影响其崩解性。
