胃膜素是一种治疗胃溃疡和十二指肠溃疡较好的药物。国内生产单位较多,虽然都是来自猪胃粘膜,但因采用的工艺路线不同,产品的质量也不同。为此,我们参考北京、上海、辽宁、福建、云南、安徽、青岛等地地方标准以及《美国新药标准和测定法》(Tests and Standards for New and Nonofficial Remidies, 1953),对各地产品进行了质量考察。一、考察项目 1.物理外观:白色至黄色粉末或微棕黄色颗粒。 2.鉴别:2%溶液的pH3.7～6.5。 3.粘度:2%溶液与水对比1.30～3.50(25℃)。
Gastrodin is a good drug for the treatment of gastric ulcer and duodenal ulcer. More domestic production units, although all from the pig stomach mucosa, but because of the different process routes used, the quality of the product is also different. To this end, we refer to the local standards of Beijing, Shanghai, Liaoning, Fujian, Yunnan, Anhui and Qingdao as well as the “Tests and Standards for New and Nonofficial Remidies” (1953) Inspected First, the inspection project 1 physical appearance: white to yellow powder or slightly brown yellow particles. 2. Identification: 2% solution pH 3.7 ~ 6.5. 3. Viscosity: 2% solution and water contrast 1.30 ~ 3.50 (25 ℃).
