Medicine has been closely related to people's lives since ancient times. The production of medicines started from traditional medicine, and later evolved to the separation and extraction of natural medicines from natural substances, and then gradually developed and established an industrial production system for chemical medicines, while pharmaceutical excipients, in the pharmaceutical industry plays a vital role in, for example, Silicon Dioxide SiO2.

Pharmaceutical excipients refer to the excipients and additives used in the production of drugs and the formulation of prescriptions. In addition to excipients, acting as carriers, and improving stability, they also have important functions such as solubilization, solubilization, and sustained and controlled release. Important ingredients that affect the quality, safety and efficacy of medicines.

As a widely used inorganic material, Silicon Dioxide SiO2 is also a very useful pharmaceutical excipient in the pharmaceutical field. The auxiliary material, silica, with the structural formula mSiO2·nH2O, is a white powder with good fluidity, high purity and no pollution. It has the characteristics of small particle size, large specific surface area, and many pores. adsorption performance. The addition of Silicon Dioxide SiO2 as a pharmaceutical excipient can effectively improve the quality and performance of pharmaceutical preparations, especially tablets, and greatly improve the market competitiveness of pharmaceuticals. Its application in pharmaceutical preparations has received more and more attention.
