Pharmaceutical preparations are composed of three major elements: qualified raw materials, appropriate amounts of excipients, and scientific production technology. Among them, the quality of raw materials is the first element that affects pharmaceutical preparations. Pharmaceutical outsourcing process institutions can provide outsourcing process R&D and production of intermediates, bulk drugs, preparations, etc. Starting materials are anRead more

Compared with the production of pharmaceutical preparations, the production process of API drugs has its own characteristics. Because the production process of APIs often includes complex chemical and biological changes, and has a relatively complex intermediate control process, by-products are often produced during the production process, which usually requires a purification process. At present, manyRead more

The preparation and research of APIs is at a critical position in the chemical drug R&D process, and the structure of the prepared compounds is consistent to ensure that subsequent quality control studies, pharmacology and toxicology studies, and clinical studies are meaningful. Through the structure of the synthesized APIs Confirmation can characterize whether the structureRead more

The new drug development stage includes 4 important stages: target determination, model establishment, lead compound discovery, and lead compound optimization. After the target is determined, a biological model such as an in vitro ADME model of a drug should be established, which is mainly used to study drug absorption, distribution, metabolism and drug toxicity, inRead more
