There are many types of drugs, including chemical synthetic drugs, natural drugs and biological products. Its treatment range is wide, covering various diseases and symptoms, such as infections, chronic diseases, pain and mental disorders.
[0003] Drug impurity filtration is a key pharmaceutical process that aims to remove impure substances from drugs to ensure the purity and quality of the product. This process usually uses a variety of technologies, including physical filtration, chemical treatment and biological separation. These methods are usually selected and optimized according to the characteristics and preparation process of the drug to ensure that the final product meets the purity standards specified in the pharmacopoeia.
