Everolimus is primarily used in the medical field for its immunosuppressive and anticancer properties. It is commonly prescribed to prevent organ rejection in patients who have undergone kidney or liver transplants. By inhibiting the mTOR pathway, it helps to suppress the immune system, reducing the risk of the body attacking the transplanted organ. In oncology, everolimus is utilized to treat certain types of cancer, including advanced renal cell carcinoma, breast cancer, and neuroendocrine tumors. It works by slowing down the growth and spread of cancer cells, thereby helping to manage the disease and improve patient outcomes. Additionally, everolimus is used in the treatment of tuberous sclerosis complex (TSC), a genetic disorder that causes benign tumors to grow in various organs. It helps to reduce the size of these tumors and alleviate associated symptoms, improving the quality of life for patients with this condition.
