The invention discloses an antibacterial agent suitable for oral administration to animals, the antibacterial agent comprises quinolone drugs or their pharmaceutically acceptable salts, and tannins or their pharmaceutically acceptable salts. The invention also discloses a preparation method and application of the antibacterial product, and a pharmaceutical preparation containing the product. According to the research of the present invention, it is found that the combination of quinolones and tannins eliminates the unpleasant smell and taste of quinolones, and solves the problem that the existing quinolones cause the smell and/or taste sensitive animals to be affected by the smell and taste of the drugs themselves when taking the medicine. At the same time, the results of the pharmacodynamic test show that the product of the present invention has obvious synergistic bacteriostatic effect on sensitive bacteria, which can significantly reduce the minimum inhibitory concentration of quinolones and reduce the quinolones. It has a good application prospect. |
