5-[(dimethylamino) methyl]-2-furazolcarbinol reacts with cysteine to produce 2-[[5-(dimethylamino)] methyl -2-furyl] methyl] Thio] ethylamine. Dissolve n-methyl-1-methylthio-2-nitrovinylmethylamine in water, heat and stir, drop the substance obtained from the surface, react for a certain time, add 4-methyl -2-pentanone, ranitidine was obtained after further treatment.
histamine H: receptor antagonist. It can effectively inhibit the gastric acid secretion caused by basal gastric acid and gastrin stimulation, and reduce the activity of gastric acid and gastric enzyme. The effect is 5~8 times stronger than cimetidine, and the maintenance time is long, and there is no adverse reaction of cimetidine on the central nervous system, gonad and so on. It is mainly used for the treatment of active gastric and duodenal ulcer, reflux esophagitis, Zhuoyi AI syndrome and other high gastric acid secretion diseases, acute gastric mucosal damage and non-steroidal anti-inflammatory drugs (including aspirin) in stress state. Caused by acute gastric mucosal injury, general anesthesia or after major surgery and debilitating Coma patients to prevent acid reflux and aspiration pneumonia.
