Abstract

The invention discloses gel preparation used for tumor in-situ treatment and a preparation method of the gel preparation. The gel preparation comprises taxol micella, cis-platinum, thermos-sensitive hydrogel and normal saline in the weight ratio of (100-250): (4-20): (2000-4000): (8000-6000), wherein the thermos-sensitive hydrogel is block polymer polyethylene glycol-polycaprolactone-polyethylene glycol. The gel preparation is used for local in-situ treatment of tumors, targeting of cis-platinum and taxol micella drugs can be improved, toxic and side effects are reduced, the difficulty of fixed-point application and in-situ local treatment of deep cancer tissue of cancer patients is solved and durable curative effect is achieved. In addition, the gel preparation has dual release effect, cis-platinum and taxol micella can be loaded at the same time, cell cycle-specific agent and non-specific agent are matched to achieve synergic effect and killing effect of the tumor tissue is improved.
