The extrinsic release rate is a vital technical parameter for evaluating the quality of liposome-based formulations. It plays a crucial role in product development, quality control, and market approval by ensuring that formulations meet performance and safety criteria. CD Formulation provides advanced testing services to support enterprises and institutions in meeting these critical requirements, fostering innovation and quality in liposomal drug delivery systems.

The release behavior of liposomes is a key research area as it has significant implications for drug quality control and clinical application. Here are the main reasons: The release behavior can simulate drug behavior in the body, predict in vivo performance, reduce the risk of clinical trial failures, and ensure safety and efficacy. It also reflects the physicochemical properties of drugs, like morphology, particle size distribution, encapsulation rate, and leakage rate. This information is crucial for differentiating batches of formulations. Studying release helps understand liposome action in vivo and in vitro, crucial for developing new drugs and improving existing ones. The release behavior is an important quality control indicator. Guidelines require thorough research during liposome development to ensure release, absorption, in vivo safety, efficacy, and stability. Therefore, studying it is important for drug quality control, clinical application, and regulatory compliance.
Our in vitro release condition screening primarily encompasses the selection of release medium, temperature, and drug concentration. Based on the separation techniques for free drugs and liposome-encapsulated drugs, we propose the following methodologies: dialysis method for separation; centrifugation method for separation; gel chromatography method for separation.
This service refers to the development and establishment of analytical methods for different liposomal formulations.
For nano liposome drugs, in vitro release data under simulated physiological conditions should be able to reasonably explain their clinical efficacy. Therefore, the release of data under QC release conditions should have distinguishing power, need to be able to draw a complete release curve, should be released to reach the plateau period, or release more than 80%. If there is a technical guideline or guiding principle for drug research, it can be evaluated according to law.
