1. Bioadhesive drug ingredients, including an ion therapeutic agent and an ion polymer, in which the polymer has enough ionization property to provide ions together with the therapeutic agent, so that the ingredients can release the therapeutic agent in a controlled manner for a long time, When the composition does not need a latex system, it can be used for the composition required in 2-1 of the treatment medium, wherein the polymer is anion 3-1, wherein the polymer is ion;The composition also includes a biological adhesive, 4. The composition required in Item 2, wherein the therapeutic agent is anionic, and the composition also includes a complex blinding agent, which forms a complex structure with the therapeutic agent, and its complexity is combined with the anionic polymer. When the polymer is sufficiently ionized to combine with the angular compound, it can also provide biological bonding of the components. 6. The composition of claim 2, wherein the polymer is sufficiently ionized to provide biological bonding.In the case that the polymer is a polycarbonate polymer extracted from a biological adhesive, it is mixed with water but insoluble in water. 8. The composition required in Item 7, wherein the polymer includes polycarbonate 9. In this case, release one treatment agent at least 6 hours and 10 minutes; in this case, release the components required in Item 2 for at least 12 hours.
