The quality of medicines is directly related to people's health and safety of life. For this reason, the production of medicines must comply with the national pharmacopoeia and other medicine production management regulations. The finished injection should not contain any live microorganisms. No matter what method is used for preparation, it must meet the requirements of pharmacopoeial sterility inspection. Pyrogen-free is an important quality indicator of injections, especially large-dose pharmaceutical preparations for intravenous injection and spinal cavity injection, all require pyrogen inspection and can be used only after being qualified. The injection solution should be checked under specified conditions, and there should be no visible turbidity or foreign matter. Injections should not cause tissue irritation or toxic reactions, especially non-aqueous solvents and some additives. The injection is required to have the necessary physical and chemical stability to ensure that the product is safe and effective during the storage period.
