CN201710877397.6 exposes a preparation technique of high-purity antivenom, including product and prep work procedure. The here and now innovation tackles the prep job treatment of pepsin food digestion, Octanoic Acid rainfall separation and ion chromatography purification, makes use of n-octanoic acid to generate rains for hetero-impurity healthy proteins other than immunoglobulin (IgG), and utilizes Octanoic Acid to carry out rains to get rid of hetero-impurities The albumen is detoxified by ion chromatography once again, and likewise the technical plan that the pureness of antivenom F (ab’) 2 is improved has really gotten over the troubles and lacks that the previous art exists that the pureness is difficult to boost, and that the snake poison injury deals with allergic negative results, The anti-snake poison F(stomach muscle’) 2 preparation attains the objective of boosting the pureness index as well as reducing the allergic damaging results of snake venom-injured patients.
CN200910003964.0 supplies a percutaneous absorption spot, which is a percutaneous absorption area of fentanyl or its citrate, in addition to is composed of a support layer, a pharmaceutical prep work layer, as well as a protective layer. The support layer is built from a product that is nonporous to the medicine; the medicine prep job layer is made from glue, polyethylene glycol monohexadecyl ether, n-octanoic acid and/or oleic acid, diethanolamine laurate and also fenamic acid. It consists of tanyl or fentanyl citrate; the protective layer is a film or paper whose area is nonporous to the medicine and also covered with a silicon polymer that can be removed prior to use. The weight proportion of sticky, polyethylene glycol monohexadecyl ether, Octanoic Acid and/or oleic acid, diethanolamine laurate along with fentanyl or fentanyl citrate in the pharmaceutical preparation layer is: 100:1 ~ 10:1 ~ 10:1 ~ 5:3 ~ 15. The transdermal absorption spot of the present moment production can be well related to the skin, as well as the medicine fentanyl can be soaked up quantitatively by the body with the skin for an extended period of time, so the analgesic result is lasting, safe and additionally reliable.
