人胰岛素与动物胰岛素有何不同根据种属来源不同,胰岛素可分为基因合成的人胰岛素和动物胰岛素。由于动物胰岛素在化学结构上与人胰岛素不完全相同,因此,存在一定的免疫原性,可能产生抗体,部分患者注射后出现皮肤过敏。另外,动物胰岛素的效价比人胰岛素低,当由动物胰岛素换用人胰岛素时,剂量需相应减少15%-20%。 What is the difference between human insulin and animal insulin? According to different genus sources, insulin can be divided into genetically synthesized human insulin and animal insulin. Because animal insulin is not exactly the same in chemical structure as human insulin, it has some immunogenicity and may produce antibodies. Some patients have skin allergies after injection. In addition, the potency of animal insulin is lower than that of human insulin. When insulin is replaced by animal insulin, the dosage should be reduced by 15% -20%.
