 Compatibility of Drug Contact System
 

With reference to the regulations and guiding principles promulgated by the State Drug Administration and relevant foreign institutions, the test scheme was designed for the compatibility research of drug contact system, and simulated extraction test, extract research, adsorption and migration research, safety evaluation and other work were carried out.Guided by safety assessment and on the premise of improving the efficiency of drug research and development, the center is committed to providing accurate and rapid solutions for compatibility research of drug contact systems and comprehensive and reliable compatibility research data for rapid drug declaration.

Main business:
 

1, According to the decision tree of packaging materials research, design compatibility research scheme for all kinds of drug packaging and use systems, provide experimental data, and write necessary data for drug declaration.

2. Study on the extraction of various materials and additives of drug packaging materials, production components and drug delivery devices.

3. According to the collected production information of drug contact system, focus on the possible or extracted toxic substances, further carry out safety and toxicological evaluation, and give the conclusion of compatibility research.

Research on Polymer Impurities

The center has established joint laboratories with Shimadzu and Thermo Fisher Scientific, the world's top instrument and equipment companies, and is committed to cooperating in the development of new detection technologies and methods.
 

Polymers are allergens that trigger the immediate allergic reaction of β -lactam antibiotics, and the study of polymers is one of the key points of antibiotic quality control.At present, gel filtration chromatography (molecular exclusion chromatography), ion exchange chromatography, reversed-phase chromatography and capillary electrophoresis are commonly used to detect polymers, among which gel filtration chromatography is the main method.

In recent years, it has been reported that liquid chromatography-mass spectrometry can be used to detect polymers, but only the total amount of impurities in polymers can be detected, and the structure of individual polymers cannot be separated and identified.We have established a joint laboratory with Shimadzu Mass Spectrometry Innovation Center, and jointly developed multidimensional chromatography/mass spectrometry technology to separate and identify the structure of polymers.To provide technical reference for enterprises to improve process, research and development of dosage forms, and improve quality, and to ensure the safety of medication for patients.At the same time, it can also provide scientific basis for improving pharmacopoeia standards.
 

Instruments and equipment are shown in the following figure:
 

The Center and Shimadzu Joint Laboratory have carried out research work on more than 10 polymer impurities of antibiotics, and will continue their cooperation in this field in the future.At present, the database of polymer impurities is being established, and it is expected to share data and achievements with peers in the future.

Research on Unknown Impurities and Difficult-to-Obtain Impurities

The center uses the top-notch high-resolution mass spectrometry instruments and equipment of Thermo Fisher Scientific Company, and carries out cooperative research work with it to jointly solve new hot and difficult problems in the field of drug research and development, especially in the research of unknown impurities and hard-to-obtain impurities by using high-resolution mass spectrometry technology, which opens up new ideas and new fields for the quality research of innovative drugs and generic drugs.

In the process of developing pharmaceutical process routes, some processes or degradation impurities can not be purchased and synthesized through commercial channels, and it is very difficult.In this case, on the basis of consulting relevant experts, we plan to establish a LC/MS method to study it.This method can greatly shorten the research period of drug quality, improve the research efficiency, and greatly save manpower, material resources and financial resources.

 Application of Toxicity Prediction Software

When designing the top-level project, it is necessary to predict its impurities according to the preparation technology and stability of drugs, especially the genotoxic impurities which have attracted much attention in recent years.Derek and Sarah software are approved by the regulators of ICH M7 guiding principles, and developed by Lhasa limited in the UK.The software meets the requirements of ICH M7 guiding principle for the mutagenicity risk control of impurities, and can meet the requirements of the guiding principle that computational toxicology assessment method should be used instead of bacterial mutagenicity test for impurities, and automatically provide impurity grade classification.At the same time, the prediction results of this software are recognized by CDE.The use of this software can greatly improve our research and development efficiency, so that we can provide customers with more efficient and accurate services.
 

The analysis and testing center of the new leading company is still strengthening the construction of talent team, introducing more talents, expanding the scale of laboratories, using more advanced instruments and equipment, and expanding the scope of testing services.At the same time, we will unite more high-end partners to build a detection technology team with exquisite technology and excellent equipment, jointly explore new detection technology fields, help China's new drug and imitation research and development level to be in line with international standards, and let more people eat cheap drugs and conscience drugs.
