微型胶囊 Microcapsules 简称微囊,就是将固体、液体或混悬物的微小颗粒(称囊心物质)的周围包上一层薄膜(称包料)形成极为微小的胶囊,其直径从零点几微米(μ)至5,000微米。药用微囊剂外观类似散剂,在显微镜下观察,实为一分散镶嵌着药物的干燥微球体。微囊在药剂学上是一种新剂型,是在最近二十年发展起来的,这一种新技术,早在六十年代初期开始应 Microcapsules Microcapsules refers to the solid, liquid or suspension of tiny particles (known as saccanel) surrounded by a thin film (known as the package) to form a very small capsule, the diameter of a few microns from the zero ( μ) to 5,000 μm. Pharmaceutical microcapsules look like powder, observed under a microscope, in fact, is dispersed in a dry drug-embedded microspheres. Microcapsules are a new form of pharmaceutics that has developed in the last two decades. This new technology, which began as early as the early 1960s,
