Problems solved by technology

At present, there are a lot of Chinese patent medicines that have been marketed in my country for the treatment of chronic gastritis, but the general dosage forms are aging, and the traditional decoctions, granules, tablets, and capsules composed of traditional Chinese medicines ranging from a few to dozens of Chinese medicines have low bioavailability. It takes a short time to effectively act on the lesion, which is a waste of resources, takes more medicines, and the effect is relatively poor

Abstract

The invention relates to a medlar floating tablet for treating chronic gastritis and a preparation method thereof. The medlar floating tablet comprises medlar extractum, cuttlebone, hydroxy propyl methyl cellulose and hydroxyethyl cellulose, is developed according to screening of clinical prescriptions of modern Chinese medicine by combination with modern Chinese medical pharmacology and preparation method thereof; the medicinal values of the medlar and the cuttlebone and the foaming function of the cuttlebone are sufficiently utilized; and the hydroxy propyl methyl cellulose and the hydroxyethyl cellulose serve as hydrophilic gel skeleton materials, so that the medlar floating tablet can expand gradually in gastric juice to wrap carbon dioxide produced after the reaction of a foaming agent and the gastric juice so as to reduce the density of the tablet; and therefore the floating effect of the medlar floating tablet in the stomach is favorably achieved, the action time of the medlar and the cuttlebone in the stomach is prolonged, effective components are easy to absorb, the action is more durable, and the medical effect is more obvious. The medlar floating tablet is particularly suitable for chronic superficial gastritis and chronic atrophic gastritis; any toxic or side effect is not found; and the raw materials are wide in sources and low in cost, and are easy to obtain.
