碳酸氢鈉注射液是一种常用的血液解酸剂,为許多国家的药典所收载。但碳酸氢鈉很不稳定,易按下式分解: 2NaHCO_3(?)Na_2CO_3+H_2O+CO_2碳酸鈉产生后,使注射液碱性增强,不仅对机体的刺激性增大,而且以较大剂量靜注时还有溶血的危险,因此共制备方法值得加以研究。制备注射液时,为了防止碳酸鈉的生成,各 Sodium bicarbonate injection is a commonly used blood antacid, which is included in many countries’ pharmacopoeias. But sodium bicarbonate is very unstable, easy to be decomposed by the following formula: 2NaHCO_3 (?) Na_2CO_3 + H_2O + CO_2 sodium carbonate produced after the injection of alkaline increased, not only the body irritation increases, and the larger the dose of static There is also a danger of hemolysis when the note is made, so co-preparation methods deserve to be studied. In the preparation of injection, in order to prevent the formation of sodium carbonate, each
