Quick Summary

Cyclosporine is an immunosuppressant drug used to prevent the rejection of transplanted organs and treat autoimmune diseases like rheumatoid arthritis and psoriasis. It is a cyclic polypeptide derived from a fungus and works by inhibiting T cells, a type of white blood cell crucial to the immune system's response to foreign substances. Cyclosporine is often used in combination with other medications, such as glucocorticoids, to enhance its effectiveness in preventing transplant rejection.12
