The domestic pharmaceutical excipients industry started late, and there are many problems in terms of scale, management regulations, and standards. Recently, China has researched and implemented the DMF (Main Quality Management of Pharmaceutical Raw Materials) system to strengthen APIs, excipients, chemical intermediates and Management of pharmaceutical packaging materials. The purpose of promoting DMF is to improve the status quo of the auxiliary materials industry, and at the same time drive the preparation manufacturers not only the product quality, but also must go out and learn more about the whole production process and quality of the raw and auxiliary materials packaging materials, so that the quality of the auxiliary materials will be greatly improved. The auxiliary industry is good news. The 21st century international pharmaceutical market will be the world of new pharmaceutical preparations, and the advancement of preparations will certainly promote the rapid development of the pharmaceutical excipient industry. The traditional role of pharmaceutical excipients is to help release the main ingredient, to promote the dissolution of the main ingredient, or for some specialized uses. Affected by the rapid development of preparations such as bioengineered preparations, insoluble and insoluble pharmaceutical preparations, and new dosage forms of traditional Chinese medicines, the definition of pharmaceutical excipients has gradually changed, and new antibodies or other new concept products have been included in the category of pharmaceutical excipients. The development prospects of the auxiliary materials industry are promising.
