药剂学名词解释（Interpretation of pharmaceutical terms） 1. pharmaceutics: it is a comprehensive technical science to study the basic theory of drug preparation, prescription design, preparation process and rational application. 2. inclusion compound is a molecular compound formed in the enclosed block hole structure of another molecule in. The hole structure (inclusion material), are called molecular molecules embedded (drug) molecules known as guest molecules, the clathrate compound is called molecular capsule host molecules and guest molecules consisting of. Inclusion process is a physical process, not a chemical process. ? 3.: solid or liquid medicine capsule (capsule heart called) wrapped in natural or synthetic polymer materials (called tiny sacs, the capsule material which is called micro capsule, microcapsule, its diameter is 1~5000 M. 4. microsphere: a small spherical structure of the skeleton formed by dissolving or dispersing the drug in the framework of polymeric material, called microsphere. 5. liposome: composed of phospholipids and cholesterol, with a bilayer structure similar to the biological membrane.
