| titleOfInvention | A kind of gel sustained-release preparation using insoluble salt as pH adjuster and its preparation method and application |
| abstract | The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a gel sustained-release preparation using an insoluble salt as a pH adjuster and a preparation method and application thereof. The gel sustained-release preparation using the insoluble salt as a pH adjuster is obtained by blending the insoluble salt crystalline powder, the alkaline encapsulation and the polymer solution. This type of preparation is injectable, and can be transformed into a gel state after being injected into the body, thereby realizing the slow release of the package at the injection site. The insoluble salt reduces the solubility of the encapsulation in the gel by adjusting the pH inside the gel, so that part of the encapsulation is dispersed in the gel network in the form of crystals. In the early stage, the sudden release of the package from the gel is prevented, and in the later stage, as the acidic degradation products of the gel accumulate, the insoluble salt gradually dissolves to achieve the slow release of the package. The technology can be applied to the fields of long-acting analgesia, medical cosmetology and anti-tumor. |
