According to Baidu Encyclopedia, GSP refers to the quality management standard of drug circulation, aiming at ensuring the quality, safety and effectiveness of drugs in the circulation process. The newly revised GSP stipulates the basic criteria for pharmaceutical trading enterprises to engage in business activities and quality management, including the requirements for procurement, storage, sales and distribution, so as to ensure the quality control and management of drugs in the circulation process. At the same time, the newly revised GSP also stipulates the relevant requirements for drug manufacturers to store and transport drugs in the process of selling drugs and drug circulation, so as to ensure the quality and safety of drugs in the whole circulation process.
