A method for preparing a hemisphere-shaped dosage form containing drug. A high molecular weight solution containing the drug is prepared, and the solution is then dropped onto a base material. The interface phenomenon between the solution and different base materials causes the solution to form a hemisphere-shaped liquid drop dosage. After solidifying by cross-link or evaporation, a hemisphere-shaped dosage form containing drug is obtained. The advantages of the preparation method are a simple and fast process, and simple operation. Applications of the preparation method to prepare a hemisphere-shaped dosage form containing drug are also provide.
