Problems solved by technology

Although antacids are cheap, their curative effect is poor and their side effects are significant, so they are not suitable for long-term use; High; H 2 Among the receptor antagonists, cimetidine was the first to be used for peptic ulcer. It has a definite curative effect, but serious side effects may occur, so it is rarely used. Currently, ranitidine, famotidine, etc. are commonly used. , the curative effect is further improved than cimetidine, the side effects are less, and the price is much lower than that of proton pump inhibitors, so it is often used as the first choice in clinical practice

Abstract

The present invention relates to an anti-peptic ulcer drug lafutidine composition and a preparation method thereof. The composition is prepared from the following components, by weight: 5-20% of lafutidine, 70-95% of a filler, 0-15% of a disintegrating agent, 0-5% of a lubricant, 0-5% of a surfactant, an appropriate amount of a binder, and 1-10% of a coating material. The preparation method is a wet granulation tableting method. The prepared lafutidine composition has characteristics of reliable quality, stable property, simple production process, meeting of requirements of large-scale preparation production, and low cost.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a lafutidine composition and a preparation method thereof. Background technique [0002] Peptic ulcer is a common chronic and recurrent digestive system disease. It is the result of the invasive factors of the gastrointestinal mucosa exceeding the defense ability of the mucosa's own protective factors. Its incidence rate accounts for about 10% of the total population. Peptic ulcer can occur in any part of the gastrointestinal tract that is in contact with acidic gastric juice. The main diseased sites are the stomach and duodenum, with an incidence rate of 98%, and the number of patients with duodenal ulcer is far greater in patients with gastric ulcer. [0003] The formation of peptic ulcer is related to the digestion of gastric acid and pepsin, as well as the imbalance between the local mucosal damage (ulcerogenic) factors and mucosal protection (mucosal resistance) f...
