Abstract

The invention relates to a quickly dissolved film. The film is characterized by consisting of 0.01 to 90 percent of frovatripan serving as an active ingredient and the balance of film forming material and medicinal auxiliary materials. A preparation method comprises the following steps of: dissolving frovatripan and polymer in water or organic solvent or suspending other auxiliary materials, coating the solution on silicon rubber paper or a proper carrier, and drying for 0.5 to 4 hours at the temperature of between 35 and 65 DEG C; and performing shearing or film pressure separation on the dried semi-finished product to obtain the film of the specified size.
