Abstract

The invention discloses an oral quick-release membrane containing mosapride citrate solid dispersion. The membrane is prepared from the following raw material medicines and auxiliary materials in parts by weight: 3.0-8.0 parts of mosapride citrate, 10.0-20.0 parts of hydroxypropyl cellulose, 20.0-44.0 parts of hydroxypropyl methyl cellulose, 10.0-15.0 parts of methyl cellulose, 0.5-1.0 parts of carbomer, 9.0-28.0 parts of a plasticizer, and 1.0-4.0 parts of sodium saccharin. The oral quick-release membrane containing mosapride citrate solid dispersion of the invention can be conveniently applied to patients with dysphagia, the medicine release is rapid, the bioavailability and patient compliance are improved, the medicines exist in a preparation in an amorphous form, the shelf life of themedicines can be prolonged, and the effect of masking the bad taste of the medicines is realized.

Description

technical field [0001] The invention relates to a preparation, in particular to an oral immediate-release film containing mosapride citrate solid dispersion. Background technique [0002] Mosapride Citrate (Mosapride Citrate), the chemical name is 4-amino-5-chloro-2-ethoxy-N-[[4-(4-fluorobenzyl)-2-morpholinyl]methanol base] benzamide citrate. Mosapride citrate is white or off-white crystalline powder, odorless, slightly bitter. The melting point is 143-145°C. It is easily soluble in dimethylformamide and pyridine, slightly soluble in methanol, hardly soluble in 95% ethanol, insoluble in water or ether. [0003] Mosapride citrate is a new third-generation gastric motility drug, mainly used for functional dyspepsia with heartburn, belching, nausea, vomiting, early satiety, upper abdominal distension and other gastrointestinal symptoms. The drug can enhance gastrointestinal motility, but does not affect gastric acid secretion, and has no side effects such as extrapyramidal ...
