Polysebacic polyanhydride is widely used in the field of controlled drug delivery systems due to its biodegradable and biocompatible properties. It is particularly effective in delivering therapeutic agents in a sustained manner, ensuring a steady release of medication over time. This makes it highly valuable in treatments requiring long-term drug administration, such as cancer therapy, where it can be used to deliver chemotherapeutic agents directly to tumor sites, minimizing systemic side effects. Additionally, it is employed in the development of implants and injectable formulations for localized treatment of various diseases. Its ability to degrade into non-toxic byproducts further enhances its suitability for medical applications, ensuring patient safety and reducing the need for surgical removal of drug delivery devices.
