Benefits of Enteric Coated Capsules

大多数药品胶囊使用动物明胶或植物明胶制成。纤维素是一种植物明胶。这些材料在低pH值的胃液里溶解。然而,有些药品如果在胃里消化将失效,它们需要到pH值更高的肠道里吸收才能发挥药效。肠溶胶囊正是为了让药品原样通过胃部而在肠道里溶解所设计的。

肠溶胶囊是什么?

肠溶胶囊具有抗酸外壳,防止胶囊通过胃部时溶解。当胶囊到达pH值在5.5以上的碱性环境中时,也就是到达小肠时,才会溶解吸收。

功能

  • 肠溶胶囊不在口腔中融化,非常适合不需要酸性环境而激活的药品配方。胶囊外壳防止胶囊在口腔和食管区域溶解。
  • 许多药品如果在胃部溶解,将刺激胃黏膜。这些药品如果用肠溶胶囊外壳包裹,将可以直接通过胃部进入小肠后再溶解,避免刺激胃黏膜。
  • 肠溶胶囊还能防止药品里面的酶在胃部酸性环境中溶解。
  • 这种肠溶胶囊通常需要一两个小时才能溶解,非常适合注重时效性的药物治疗。
