用途: Omeprazole(Prilosec) is a proton pump inhibitor used in the treatment of dyspepsia.Target: Proton PumpOmeprazole is a proton pump inhibitor used in the treatment of dyspepsia, peptic ulcer disease, gastroesophageal reflux disease, laryngopharyngeal reflux, and Zollinger-Ellison syndrome. Omeprazole virtually eliminated intragastric acidity in all patients: the median 24 hour intragastric pH rose from 1.4 to 5.3 and the mean hourly hydrogen ion activity fell from 38.50 to 1.95 mmol(mEq)/1 (p less than 0.001). This inhibition of 24 hour intragastric acidity is more profound than that previously reported with either cimetidine 1 g daily or ranitidine 300 mg daily [1]. The pharmacokinetics of omeprazole were studied in a group of healthy male subjects after single and repeated oral doses of 30 and 60 mg. Absorption of omeprazole from its enteric-coated formulation was unpredictable. There was a highly significant increase in the area under the plasma concentration time curve (AUC) after repeated dosing. Omeprazole increases its own relative availability following repeated dosing. This may be due to inhibition of gastric acid secretion by omeprazole which is an acid-labile compound [2].Clinical indications: Duodenal ulcer; Endocrine tumor; Esophagitis; Gastroesophageal reflux; Helicobacter pylori infection; Stomach ulcer; Zollinger-Ellison syndromeToxicity: Symptoms of overdose include confusion, drowsiness, blurred vision, tachycardia, nausea, diaphoresis, flushing, headache, and dry mouth. 作用: ①消化性溃疡出血、吻合口溃疡出血。 ②应激状态时并发的急性胃黏膜损害,和非甾体类抗炎药引起的急性胃黏膜损伤; ③亦常用于预防重症疾病(如 脑出血 、严重创伤等)胃手术后预防再出血等; ④全身麻醉或大手术后以及衰弱昏迷患者防止胃酸反流合并吸入性肺炎。 5、胃酸过多患者导致反流性胃炎的酸抑制,以及胃酸过多造成的严重烧心患者。 6、消化性溃疡胃十二指肠糜烂者,在治疗中也常常会用到奥美拉唑。 物理化学性质: CAS号:73590-58-6 常用中文名:奥美拉唑 常用英文名:omeprazole 分子式:C17H19N3O3S 分子量:345.416 密度:1.4±0.1 g/cm3 沸点:600.0±60.0 °C at 760 mmHg 熔点:156ºC 闪点:316.7±32.9 °C 储存条件:2-8°C |
