有抗原性的药物大体可分为两大类:一为蛋白、多糖和多肽的大分子药物,如血清和生药制剂、疫苗、酶类,右旋糖酐等,有完全抗原性,能使机体产生相应的抗体,使机体致敏;另一类是一些化学药剂,如解热镇痛剂、镇静剂、麻醉剂及一些抗生素等小分子量物质,本身不能单独产生相应抗体,要与蛋白载体结合后,才具有抗原性,然后使机体产生相应的抗体,而使机体致敏。一般含苯核和嘧啶核的药物抗原性较强。长效药物在体内停留时间久或用药次数多者,易发生过敏,有遗传过敏体质者及妇女,亦易发生过敏;而年
Antigenic drugs can be broadly divided into two categories: a protein, polysaccharide and peptide macromolecular drugs, such as serum and crude drug preparations, vaccines, enzymes, dextran, etc., fully antigenic, can make the body produce the corresponding Antibodies, the body sensitized; the other is a number of chemical agents, such as antipyretic analgesics, sedatives, anesthetics and some antibiotics and other small molecular weight substances themselves can not produce the corresponding antibodies, to combine with the protein carrier before they have the antigen Sex, and then make the body produce the corresponding antibodies, leaving the body sensitized. Generally contain benzene nucleus and pyrimidine nucleus drugs antigenic strong. Long-acting drugs stay in the body for a long time or the number of medication more prone to allergies, those with genetic allergies and women, but also prone to allergies; the year
