Cyclosporin A

Cyclosporin A is a medication that suppresses the immune system's activity, primarily used to prevent organ rejection after transplants. It works by inhibiting certain immune cells called T-lymphocytes, which would normally attack the new organ. By doing so, it helps the body accept the transplanted organ and reduces the risk of rejection. Cyclosporin A is carefully dosed because it can have significant side effects, including kidney problems and increased risk of infection. It is a critical drug in transplant medicine and autoimmune disease management, balancing immune suppression with potential risks.
