本文着重综述药用多聚物在药剂中的应用等有关内容,供药剂工作者在选择应用这些物质时参考。多聚物的用途1)用作片剂的薄膜包衣、肠溶衣和保护膜以遮掩异味和防止变质;制备薄膜衣骨架型缓释片;作为片剂、胶囊剂的溶解阻滞剂和用作药物间配伍禁忌的隔离物,阻止制剂中主药的晶型变化;改进某些制剂的物理性和化学稳定性。2)可将一些具有固体细粒的药物和某些液体药物制成微囊,并可使其囊膜具有通透性或半通透性,利于控制释药速度。3)其分散体或乳胶粒子用来吸附药物,凝结后可 This article focuses on the application of pharmaceutical polymers in pharmaceuticals and other related content for pharmaceutical workers in the choice of the application of these materials reference. Use of polymers 1) Use as film coatings, enteric coatings and protective films for tablets to mask odor and prevent deterioration; Preparation of film-coated, cosmetical-type sustained release tablets; as dissolution inhibitors for tablets and capsules and As a drug incompatibility between the taboo of the spacer to prevent the main drug crystal form changes; improve the physical and chemical stability of some formulations. 2) can be some solid particles of drugs and some liquid drugs into microcapsules, and can make the capsule has permeability or semi-permeability, which will help control the release rate. 3) The dispersion or latex particles used to adsorb the drug, after coagulation can be
