What does the solid content mean when coating?

The solid content at the time of coating refers to the percentage of drugs contained in the coating after drug coating. In the process of drug production, coating is an important technical means, which can mask the taste and smell of drugs and increase the stability and tolerance of drugs. The solid content in coating process is one of the important indexes to measure coating technology. The higher the solid content, the better the coating quality, and the easier the coated drugs are to use.

There are many factors that affect the solid content in coatings. For example, the physical and chemical properties of drugs, the selection of coating materials, the optimization of coating process and so on. Among them, the choice of coating materials is very important, because different coating materials have different effects on the solid content and sustained release performance of drugs after coating. In addition, the optimization of coating process is also one of the factors affecting the solid content. Good coating technology can ensure uniform coating of each pill, thus improving solid content and sustained release performance.

The solid content in the coating process has an important application in drug production, research and development and quality control. For drug research and development, the solid content of coating can be used as an important index to evaluate the quality of drugs. For quality control, the solid content can be used to judge whether the quality of drug coating is up to standard. In addition, for drug production, the solid content of coating can also be used as one of the important indicators of drug anti-counterfeiting. By controlling the solid content of drugs, drug loss and counterfeiting can be avoided.
