药用高分子系指利用功能高分子聚合物的主链或支链,结合具有药理活性的某些药物基团,使其成为在体内容易降解定释,有足够药理活性的高分子药物,这类新型药物具有低毒、高效、长效、定向、控释等特点;高分子药物系指在药物制造过程中,根据功能高分子聚合物的物化特性,分别用于药物的稀释剂、粘合剂、包埋材料、微型胶囊、包衣或内外包装材料等,其本身并不具有药效,只是药物成品过程中,起着不可缺少的从属辅助作用或者强化作用。实际上两者并没有严格界限。 Medicinal macromolecule refers to the use of functional polymers of the main chain or branched, combined with the pharmacological activity of certain drug groups, making it easy to degrade the body in vivo release, have sufficient pharmacological activity of the polymer drugs, which Class of new drugs with low toxicity, high efficiency, long-lasting, directional, controlled release and other characteristics; polymer drug refers to the drug manufacturing process, according to the physical and chemical properties of functional polymers, respectively, for drug diluent, adhesive Agents, embedded materials, microcapsules, coating or packaging materials, etc., itself does not have the efficacy, but the process of finished drugs, plays an indispensable subsidiary supporting or reinforcing effect. In fact, there is no strict limit between the two.
