The present invention belongs to the field of pharmaceutical preparations, particularly relates to an 
olanzapine oral instant membrane agent, a preparation method and pharmaceutical uses thereof. The membrane agent comprises the following components, by weight, 1-30% of 
olanzapine, 40-90% of a 
polymer membrane forming material, 0-40% of a 
plasticizer, 0-30% of a flavoring agent, and 0-5% of otherauxiliary agents. The 
olanzapine oral instant membrane agent has the following characteristics that: no water is required during administration, the olanzapine oral instant membrane agent can rapidlymelt in mouth, phenomena of 
drug hiding in mouth and 
drug spitting of 
schizophrenia patients can be avoided, and patient medication compliance is easily improved. With the preparation method, the main 
drug of the olanzapine oral instant membrane agent has characteristics of good dispersing effect in a 
hydrophilic matrix glue liquid, good finished product appearance, rapid 
dissolution and good stability. In addition, characteristics of accurate product 
dose and no dust flying during a production process are provided, and problems of labor protection and environmental
