In-situ drug-loaded hydrogel, preparation method therefor and use thereof |
| abstract |
The present invention relates to an in-situ drug-loaded hydrogel, a preparation method therefor and the use thereof. A method for preparing a multi-arm polyethylene glycol derivative complex. The method comprises pre-freezing a multi-arm polyethylene glycol derivative solution, and then sequentially performing three stages of drying. The in-situ drug-loaded hydrogel comprises the multi-arm polyethylene glycol derivative complex, a phosphate buffer solution, a buffer salt solution and a drug. The in-situ drug-loaded hydrogel of the present invention can be used for sealing, repairing, filling or treating tissue wounds. |
