In the drug manufacturing process, drug raw materials, intermediates, and finished products are three important stages. They represent different links in drug production, each with its own characteristics.

　　1. Drug Raw Materials

　　Drug raw materials are the foundation of pharmaceutical manufacturing, including various chemical substances and biological materials. These raw materials are carefully selected and processed to ensure their purity and quality. The quality of raw materials directly affects the safety and efficacy of the final drug. Therefore, strict screening and testing of raw materials are key steps in the drug production process.

　　2. Drug Intermediates

　　Drug intermediates are products obtained through preliminary processing based on raw materials. This stage usually includes processes such as mixing, grinding, and granulating to prepare for subsequent steps like tablet pressing and filling. Quality control of intermediates is equally important because it directly relates to the quality and stability of the final product.

　　3. Drug Finished Products

　　Drug finished products are the final products obtained after a series of manufacturing processes, usually in the form of tablets, capsules, injections, etc. Finished products must comply with national drug standards and undergo strict quality inspections to ensure their safety, efficacy, and stability. Patients use drugs under the guidance of doctors to achieve therapeutic goals.

　　In summary, drug raw materials, intermediates, and finished products are three important stages in the drug manufacturing process. Understanding these concepts helps us better comprehend the drug production process and quality control, thereby ensuring the safety and effectiveness of medication.
