滴法制丸剂是将有效物质溶于或乳化于具有适宜融点的基质中,以熔融状态滴入不相混合而比重稍低的冷却液内。当熔融物落经冷却介质时,因表面张力而形成圆形,並逐渐冷凝而集于器底。也可以採用比重较大的冷却液,熔融物由器底导入,逐渐凝固而上升于液面。滴法制丸剂的优点在于:设备简单;制造容易;过程中与空气接触的机会少,因此很安定; Dropping method pills is the effective material dissolved or emulsified in a suitable melting point of the matrix, the molten state was dripped into the mixing is not mixed with a lower specific gravity of the cooling liquid. When the melt through the cooling medium, the surface tension due to the formation of a circle, and gradually condensed to gather in the bottom. You can also use a larger proportion of coolant, the melt introduced from the bottom, gradually solidified and rose to the surface. The advantage of dropping pills is that: the device is simple; easy to manufacture; the process of contact with air less opportunity, it is very stable;
