| titleOfInvention | Oral mucosa agent containing quercetin and preparation method thereof |
| abstract | The invention discloses an oral mucosa agent containing quercetin and a preparation method thereof. The oral mucosa agent containing quercetin comprises a medicine-carrying layer, wherein the medicine-carrying layer contains 1-50 parts of quercetin, 0-5 parts of borneol, 0-3 parts of glycyrrhetinic acid and 50-95 parts of polyvinylpyrrolidone in parts by mass. The invention prepares the amorphous solid dispersion film agent by optimizing the formula and adopting the electrostatic spinning technology, and solves the problem of poor water solubility of quercetin, borneol and glycyrrhetinic acid. The dissolution and release of the medicament are delayed by forming an additive by the film forming agent and the quercetin. Meanwhile, in order to prevent excessive loss of the medicine due to dissolution in saliva, a protective film is added on the basis of the medicine film loaded with quercetin to serve as a back film, and the dissolution cannot be greatly affected due to the addition of the protective film. |
