The application belongs to the technical field of antibiotic application, and discloses that microplastics affect the absorption of ciprofloxacin in the intestinal tract through the TLR4 / NF-kappa B pathway regulating P-gp protein. Our research finds that microplastics can activate the expression of P-gp glycoprotein in intestinal epithelial cells through the NF-kappa B pathway in the intestinal tract, thereby reducing the absorption of ciprofloxacin hydrochloride in the intestinal tract, and further affecting the core mechanism of pharmacokinetics and pharmacodynamics of ciprofloxacin hydrochloride in animals. Pyruvate ethyl effectively inhibits the NF-kappa B pathway. The application also finds that after ivermectin inhibits the P-gp glycoprotein of Caco2 cells, the P-gp glycoprotein cannot efflux ciprofloxacin hydrochloride, so that the content of ciprofloxacin hydrochloride in Caco2 cells increases. Therefore, the application also protects the application of ivermectin in preparing a promoter of the content of ciprofloxacin hydrochloride in Caco2 cells incubated with microplastics.
