Medicine carrying support used for treating cervicitis and preparation method thereof

The invention discloses a medicine carrying support used for treating cervicitis and a preparation method thereof. According to the method, mainly PLGA is added into methylene chloride, a certain amount of NaCl and ceftriaxone sodium are added, and mixtures are dispersed into uniform liquid through a homogenizer. Then the liquid is added into a PVA solution and stirred so that microspheres carried with ceftriaxone sodium can be obtained through stirring, freezing drying is performed after the microspheres are washed through deionized water, and then the dried medicine carrying microspheres are obtained. The microspheres are placed in a cylindrical mold and placed in a 70-DEG C drying box, temperature is preserved for 3 h, and the final medicine carrying support is obtained. Because PLGA degradation products are lactic acid and acetic acid, no side effects on bodies are caused, degradation of the support is performed along with medicine release, medicine directly acts on the inflammatory portion, and the medicine carrying support has great significance in treating cervicitis.
