| abstract |
The invention provides an elastic film, a preparation method and an application. The elastic film includes silicone rubber and a drug, the drug is uniformly dispersed in the silicone rubber, and the drug includes estrogen; by adjusting the particle size and quality of the drug, Control the sustained release and release of the drug, so as to achieve a better therapeutic effect and a longer release cycle, and ensure a low-dose and high-efficiency therapeutic effect. The silica membrane has high stability and porosity, which is convenient for drug dissolution. and release; the preparation method of the matrix elastic film is simple, the raw materials are readily available, the price is low, and it is convenient for industrial large-scale production and application. |
