Cyclosporine A

Cyclosporine A is an immunosuppressant medication used mainly to prevent the body from rejecting transplanted organs like kidneys, liver, or heart. It works by selectively inhibiting certain immune cells, particularly T-cells, which are responsible for attacking foreign tissues. By doing so, it helps the transplanted organ survive and function properly. Cyclosporine A is also used to treat certain autoimmune conditions, where the immune system mistakenly attacks the body's own tissues. While effective, it requires careful monitoring due to potential side effects, such as kidney damage or increased susceptibility to infections.
