Aseptic preparations include injections directly injected into the body or non-gastrointestinal preparations directly applied to the wound or mucosa. Due to the special administration site of this type of preparation, the quality and safety risk of aseptic preparation is significantly higher than that of other types of preparation, and the sterility of the final product must be guaranteed. For liposome injections, sterility checks, and endotoxin analysis are also necessary tests for quality control. CD Formulation is capable of providing customers with comprehensive sterility and endotoxin testing services.
With the progress of science and technology, the method of sterility examination of liposome injection has become more and more scientific and accurate, which better guarantees the safety of patients. At present, many rapid sterility testing methods are also gradually emerging, which will be a trend. But both the new and old methods have limitations: neither sampling nor testing can fully guarantee detection of potential microbes. Therefore, we should pay more attention to the whole process of aseptic control of drug production to ensure the aseptic quality attribute of drugs.

Sterility testing is performed for pharmaceutical products that necessitate sterility, such as injectables, implants, and bandages. The examination is carried out under aseptic conditions to identify any viable microorganisms. We provide analytical techniques, including thin-film filtration and direct inoculation, to assist our clients in conducting sterility testing on liposome injectables, encompassing method development.
We offer a variety of endotoxin tests, including animal-based tests(e.g. gel method and photometric method) and artificial recombinant methods. In addition, we can provide method development and validation services.

Results: This study aims to highlight the influence of physicochemical properties on the behavior of nanomedicine, and the extent to which carrier structure and physicochemical characteristics influence the effectiveness of formulations. To this end, the authors conducted case studies on two commercially available Doxil nanosimilar preparations and their respective carriers, endotoxins, and cytotoxicity.
