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