Cyclosporine

Cyclosporine represents one of the most significant breakthroughs in modern transplant medicine, fundamentally changing the landscape of organ and tissue grafting. As a calcineurin inhibitor, it acts as a potent immunosuppressive agent, selectively modulating the immune response to prevent graft rejection. Its introduction in the 1980s dramatically improved one-year survival rates for organ transplants, moving the procedure from an experimental last resort to a standard of care. Beyond transplantation, its targeted mechanism has found applications in managing severe autoimmune conditions, offering a lifeline when conventional therapies fail.
