Abstract

The invention discloses a camostat mesilate orally disintegrating tablet, and a preparation method and new application thereof. The orally disintegrating tablet comprises the components in percentage by weight: 10-30 percent of camostat mesilate serving as a main material, 40-70 percent of a filler, 0-20 percent of an adhesive, 2-10 percent of a disintegrating agent, 2-8 percent of a corrigent, 0-5 percent of a flow aid and 0.5-2.5 percent of a lubricating agent. The preparation can be obtained by a wet granulation tabletting method or a direct powder tabletting method. The invention provides the camostat mesilate orally disintegrating tablet which is convenient to take, has a good taste and a quick response to adaptation diseases, and is particularly suitable for old people and children suffering from dysphagia and patients suffering from mental disease, and the medication compliance of the patients can be greatly improved; meanwhile, not only can a product prepared by the method disclosed by the invention be used for the existing adaptation diseases such as chronic pancreatitis acute episodes and postoperative reflux esophagitis, but also a research shows that the product has a new treating effect on oral mucositis caused by chemotherapy.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to an orally disintegrating camostat mesylate tablet, a preparation method thereof and a new application thereof. Background technique [0002] Camostat mesilate (Camostat Mesilate) chemical name is dimethylcarbamoylmethyl 4-(4-guanidinobenzyloxy) phenylacetic acid mesylate, which is a synthetic non-peptide protease inhibitor. It can relieve the acute attack of chronic pancreatitis and improve the symptoms of postoperative reflux esophagitis. After oral administration, this product quickly acts on the body's kinin system, fibrinolytic system, coagulation system and complement system, immediately blocks the activity of related enzymes and inhibits their abnormal hyperactivity, thereby relieving the symptoms and pain of chronic pancreatitis and improving amylase. value. In addition, it can improve postoperative reflux esophagitis by inhibiting trypsin in the re...
