罗瓦尔精(Novalgin)又名安乃近(Analginum),在配制25%及50%的注射液时,如不加任何稳定剂,由于从調配到灌封的时间的長短不等,因此含量有不同程度的降低。配制后立即測定含量相当标示量100%,一小时后是97%左右,兩小时后約95%,四小时后就只有約85%,时間再長就更加降低。这問題發现以后,我們除了加快操作外,就是多加原料2%到 Novalgin, also known as Analginum, is formulated with 25% and 50% injections, without any stabilizer, and varies in the length of time from formulation to potting Different degrees of reduction. Determination of the content immediately after the preparation of a marked amount of 100% marked an hour after about 97%, about 95% after two hours, only about 85% after four hours, the longer the time even more reduced. After this problem was discovered, apart from expediting the operation, we added 2% more raw materials
