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.
A method for preparing a micro-particle drug in hemisphere-shaped dosage form, comprising:
7-8. (canceled)
A micro-particle drug in hemisphere-shaped dosage form, comprising at least 1%˜5% drug, 1%˜40% alginate and 55%˜98% water.
A micro-particle drug in hemisphere-shaped dosage form, comprising at least 0.1%˜40% drug and 60%˜99.9% poly lactic acid.
