Description
Technical field
The present invention is the Pharmaceutical composition of active component for a kind of pharmaceutical salts with rebamipide, belongs to medical technical field.
Background technology
PUD comprises gastric duodenal ulcer, is clinical common disease.Sickness rate at Chinese peptic ulcer improves (more than 10%) year by year, and some areas have had a strong impact on patient's quality of life up to 13-28%.The medicine of present treatment peptic ulcer mainly contains proton pump inhibitor and the H2 receptor is picked up anti-agent; These medicines all are to improve the various symptoms that ulcer causes rapidly through strong gastric acid inhibitory secretion; But because effect is very fast; So have ulcer to be prone to the problem of recurrence, the back 1 year relapse rate that heals is up to 60-70%.Nineteen ninety, Tarna wski at first proposes the notion of ulcer healing quality, thinks that the healing of peptic ulcer should only not paid close attention to ulcer healing speed, more should pay attention to the ulcer healing quality, i.e. really healing fully of ulcer from the gastric mucosa 26S Proteasome Structure and Function.Focus on the aggressive factor of minimizing gastric mucosa at present clinically for the treatment of peptic ulcer,, just causing clinicist's attention and be directed against the treatment of strengthening the gastric mucosa reparation as according to helicobacter pylori and gastric acid inhibitory secretion.
It is different with proton pump inhibitor antiulcer mechanism that rebamipide and H2 receptor are picked up anti-agent; Mainly be to synthesize and links such as gastric mucus secretion, removing oxygen-derived free radicals through increase gastric mucosal blood flow, PGE2; The improvement of facilitating digestion road ulcer healing and inflammation; Reduce ulcer recurrence, and can improve eradication rate helicobacter pylori.Not only gastritis, gastric ulcer are had good efficacy, and can alleviate NSAIDs, the microbial gastric mucosa injury of helicobacter pylorus.Rebamipide has become the first-selected medication of gastric mucosal protection at present, and supply falls short of demand for product.Rebamipide listing at present have only tablet and capsule because its soluble,very slightly in ethanol or methanol is insoluble in water,, and have certain restriction for the exploitation of rebamipide liquid preparation so its oral bioavailability is had certain influence.

| Rebamipide sodium salt group | 11.65±6.04 | 72.6 |
Mice gastric mucosa injury and mucosa tissue are observed:
Ethanol causes mice gastric mucosa injury light microscopic finding: the mucous layer layer of structure is clear, and epithelium is imperfect, and local gland structure is disorderly, and the many places band shape is damaged, and deep lamina propria and tela submucosa have than multi-lymphocytes.And under the rebamipide pharmaceutical salts administration group mice gastric mucosa light microscopic: epithelium is imperfect, and it is more neat that body of gland is arranged, a small amount of exfoliative cyte fragment in the lumen of gland, the visible a small amount of lymphocyte in lamina propria deep.
Embodiment 15: the rebamipide pharmaceutical salts is to the experiment of the therapeutical effect of xerophthalmia
Experimental technique: 40 of purebred NZws, body weight 2.5～3.0kg, 4～May of age; Eyes drip Gernebcin eye drops before the art, and after continuous 3 times, choosing right eye is experimental eye; Operation is taken except that rabbit right eye lachrymal gland, behind Harder gland and the instant embrane, smears apart from bulbar conjunctiva beyond the limbus of corneae 3mm with 50% trichloroacetic acid; Process the rabbit dry eye model, begin in the 3rd week of postoperative to observe, 40 rabbits are divided into the blank group at random; The rebamipide group; Rebamipide choline salt group, rebamipide sodium salt group, 10 every group.The treatment group is with rebamipide and various pharmaceutical salts, and the blank group is used the artificial tears, respectively local eye dripping treatment rabbit model xerophthalmia; Put drops in one's eyes 3 times/day; 2/inferior,, check 1 time weekly and suffer from the wet length of canthus conjunctiva Schirmerl test 5 weeks of logotype; Breakup time of tear film and brave red colouring situation are estimated curative effect.
Experimental result: rabbit model trouble eye wet length of Schirmerl test and the brave red colored spots number average of angle conjunctiva are significantly improved than matched group after 3 weeks of observation group's treatment and 6 weeks, and the therapeutical effect of rebamipide pharmaceutical salts is more remarkable.See table 1 and table 2.
