说起药费贵不少人十分留恋过去那些一毛五分钱看一回病的好日子。但是,如果退回去,同样的病再开同样的药,却不一定还能管用。这里有着不以人的意志为转移的客观规律。一个原因是因为病毒、细菌等,经过长时间的生存竞争,有的已经对老药产生了抗药性,一些药品必须更新换代;一些药物的毒副作用,也促使更好的新药后来者居上。比如四环素会“染”黄牙齿,卡那霉素易造成聋儿,都不能继续使用。 Many people talk about drug costs are very nostalgic for those past one cents a penny to see a good day. However, if you go back and have the same disease and then start the same medicine, it may not be able to work. There is an objective law that does not depend on human will. One reason is that because of viruses and bacteria, after a long period of competition for survival, some have become resistant to old drugs and some drugs must be replaced. The toxic side effects of some drugs have also prompted better new drugs to come home later. Such as tetracycline will “dye” yellow teeth, kanamycin easy to cause deaf children, can not continue to use.
