中药调配剂量误差大是长期存在而未能解决的问题,并且这种情况有严重的趋势,医生及病人对此意见很大。中药调配剂量误差一般以相对误差来标示,相对误差=实际重量-标准重量/标准重量×100%。相对误差在《药典》上虽然没有明确的规定,但一般要求中药处方中每贴中药的各味药的重量及总重量的相对误差均应控制在±5%以内。从笔者调查的情况看,绝大多数调配的中药处方的相对误差都超过±5%,一般在10～20%之间,有的高达20%以上。造成这种现象有
The large error in the allocation of Chinese medicines is a long-standing problem that cannot be solved. This situation has a serious trend. Doctors and patients have great opinions on this issue. Dose error of traditional Chinese medicines is generally indicated by relative error. Relative error = actual weight - standard weight / standard weight × 100%. Relative errors in the “Pharmacopoeia” Although there is no clear provisions, but generally require each Chinese medicine in traditional Chinese medicine paste the weight of each herb and the total weight of the relative error should be controlled within ± 5%. From the author’s investigation, the relative errors of the vast majority of formulated Chinese medicine prescriptions exceed ± 5%, generally between 10 and 20%, and some are as high as 20% or more. Cause this phenomenon
