Raw materials refer to the raw materials used to produce various types of preparations. They are the active ingredients in the preparations, which are prepared by chemical synthesis, plant extraction, or biotechnology, and are used as medicinal powders, crystals, ointments, etc. that patients cannot take directly. According to the requirements of formulation production, the production of raw materials can be divided into aseptic raw material production and non-aseptic raw material production. Aseptic raw materials refer to raw materials that do not contain any active microorganisms, such as molds, bacteria, viruses, etc., and are upstream products of drug formulations. Take antibiotics as an example.
Antibiotics refer to a class of secondary metabolites produced by microorganisms (including bacteria, fungi, and actinomycetes) or higher animals and plants during their life processes. They have the ability to interfere with the development function of other living cells and exhibit antimicrobial or other activities. Clinically used antibiotics include extracts from microbial cultures and compounds synthesized or semi-synthesized by chemical methods. Antibiotic raw materials, such as penicillin and cephalosporin, are usually obtained through semi-synthetic methods using fermentation and chemical synthesis.
