Introduction of APIS
Jun 11, 2018

A mixture of any substance or substance used in pharmaceutical manufacture and used as an active ingredient in pharmaceuticals. This substance has pharmacological activity or other direct effects in the diagnosis of disease, treatment, relief of symptoms, treatment or prevention of disease, or can affect the function or structure of the body. The material used to produce various kinds of preparations, is the effective component of the preparation by chemical synthesis, plant extraction or biological technology to be used as medicinal powder, crystallization, extract and so on, but the patient can not take directly. An effective component of a drug. Only when the API is processed into a pharmaceutical preparation can it become a medicine for clinical use.  According to its source, API can be divided into two categories: chemical synthetic drugs and natural chemical drugs. Chemical synthetic drugs can also be divided into inorganic synthetic drugs and organic synthetic drugs. 

Inorganic compounds are inorganic compounds (very individual elements), such as aluminum hydroxide and magnesium silicate, which are used for the treatment of gastric and duodenal ulcers. The organic synthetic drugs are mainly made from basic organic chemical materials, such as aspirin, chloramphenicol, caffeine, and so on by a series of organic chemical reactions. Natural chemical drugs can be divided into two categories: biochemical and phytochemical according to their sources. Antibiotics are generally made by microbial fermentation and belong to the category of biochemistry. In recent years, a variety of semi synthetic antibiotics are synthesized by combining biosynthesis with chemical synthesis. In the raw material medicine, the organic synthesis medicine's variety, the output and the output value occupy the biggest proportion, is the chemical medicine industry main pillar. The quality of the API determines the quality of the preparation, so its quality standard is very strict. All the countries of the world have formulated strict national pharmacopoeia standards and quality control methods for the widely used pharmaceutical materials.
