What are chemical apis? What is the difference between chemical apis and chemical products

First, what are chemical apis

Chemical apis are powders, crystals, extrusions, etc. prepared by chemical synthesis, plant extraction or biotechnology, which are used for medicinal purposes but cannot be taken directly by patients. The drug is processed from the powder, crystal and extract state into the form of administration (such as tablet, capsule, injection, pill, ointment, etc.) that is convenient for the patient to take. These forms of administration are called drug dosage forms.

Specific API after processing - Pharmaceutical product API designation is mainly relative to the drug product. Mainly raw materials obtained by chemical processing means, raw materials for the production of finished drugs such as cefpirome sulfate for injection are drugs, then cefpirome sulfate is the bulk drug.

According to its source, apis are divided into two categories: chemical synthesis drugs and natural chemical drugs.

1, chemical synthesis drugs can be divided into inorganic synthesis drugs and organic synthesis drugs. Inorganic compounds are inorganic compounds (very individual elements), such as aluminum hydroxide, magnesium trisilicate for the treatment of gastric and duodenal ulcers; Synthetic organic drugs are drugs (such as aspirin, chloramphenicol, caffeine, etc.) prepared from basic organic chemical raw materials through a series of organic chemical reactions.

2. Natural chemical drugs can also be divided into biochemical drugs and phytochemical drugs according to their sources. Antibiotics are generally produced by microbial fermentation and belong to the category of biochemistry. In recent years, many semisynthetics antibiotics are the combination of biosynthesis and chemical synthesis. As the main pillar of the chemical pharmaceutical industry, the variety, yield and output value of organic synthetic drugs account for the largest proportion. The quality of API determines the quality of the preparation, so its quality standards are very strict. Countries all over the world have formulated strict national pharmacopoeia standards and quality control methods for its widely used API.

Second, what is the difference between chemical apis and chemical products

Chemical apis are raw materials for the production of various reagents, which are relatively pure and relatively small in quantity.

Chemical raw materials refer to all kinds of raw materials used in chemical industry, possibly composite raw materials, raw materials used to deal with chemical products, the purity is not so high.

Chemical raw materials refer to raw materials used in the production of various kinds of preparations, chemical synthesis, plant extraction or the preparation process of biotechnology.

There are many kinds of chemical raw materials and their uses are wide.

There are five to seven million chemicals in the world, and more than 100,000 are in circulation. More than 1,000 new chemicals are produced every year, and 150 to 200 of them are considered carcinogens.
