The application belongs to the technical field of pharmaceutical preparations, and particularly relates to a mononitrate isosorbide oral dissolving film and a preparation method thereof. The mononitrate isosorbide oral dissolving film preparation is composed of a drug-containing layer and isolation layers which are compounded on the upper and lower surfaces of the drug-containing layer. The drug-containing layer comprises the following raw materials in percentage by mass: cyclodextrin-encapsulated mononitrate isosorbide 10-60%, film-forming material 20-80%, plasticizer 0-20% and auxiliary material 0-10%. The isolation layer comprises the following raw materials in percentage by mass: film-forming material 70-100%, plasticizer 0-30% and auxiliary material 0-10%. The mononitrate isosorbide oral dissolving film prepared by the application has the advantages of smooth appearance, good taste, uniform drug content, rapid dissolution under the action of saliva after entering the mouth, and further release and absorption, which greatly improves the drug administration compliance and solves the problem of surface crystallization of mononitrate isosorbide after long-term storage.
