The invention belongs to the technical field of medicine, and in particular relates to a drug delivery system for a gel drug-carrying patch. The gel drug-carrying patch is a lipid gel, which is a Liquid crystal is the matrix, and also includes drugs, photothermal agents, anhydrous ethanol and deionized water; the gel drug-loaded patch drug delivery system is to stick the drug-encapsulated gel drug-loaded patch on the skin defect, and use Near-infrared spectrum radiation on the surface of the gel drug-loaded patch, the photothermal agent generates heat after receiving near-infrared radiation, and induces the phase of the lipid gel to change into liquid, release the drug, stop the irradiation, the temperature drops, and the phase changes from liquid again into a gel, stopping the release of the drug. The invention encapsulates the drug and the photothermal agent in the lyotropic liquid crystal, regulates the release of the drug by controlling the temperature of the gel drug-carrying patch, and achieves the effects of promoting blood circulation, removing blood stasis, reducing swelling and relieving pain, thereby reducing its side effects and improving the utilization value of the drug . |
