The invention provides a method for preparing an oral dissolving membrane for animals by using a micron-sized emulsified suspension homogeneous solution. The method comprises the following steps: preparing a membrane-forming material, an emulsifier and a water-insoluble substance into a suspension for later use in a
solvent; adding other components, controlling the temperature, and uniformly mixing to prepare a suspension film-forming
system; adding auxiliary materials; removing bubbles and injecting into a
coating groove; flattening and
coating treatment is carried out; and
cutting after
drying. The film is suitable for animals capable of being subjected to individualized operation, such as pets, breeding
livestock and young
livestock, natural alternative substances can be added into the film, the film can be accurately delivered, act on the
oral cavity in a targeted mode and efficiently utilized, the first-pass effect is avoided through
oral mucosa absorption, the
bioavailability and the effect taking speed are improved, in the
coating and film forming process, the
utilization rate of
power equipment is increased, and the cost is reduced. And the production cost is reduced. Individualized medication and traceable recording are achieved, cross
contamination of group medication is avoided, and the feasibility, reliability and effectiveness of an anti-reducing and anti-replacing scheme are improved.
