Cyclosporine is an immunosuppressive agent primarily used to prevent organ rejection in patients who have undergone kidney, liver, or heart allogeneic transplants. It works by suppressing the immune system to prevent the body from attacking the transplanted organ. In addition to its role in transplant medicine, cyclosporine is also used to treat certain autoimmune diseases, such as rheumatoid arthritis, when other treatments, like methotrexate, have not been effective. It is also prescribed for conditions like psoriasis and inflammatory eye diseases such as chronic dry eye (keratoconjunctivitis sicca).

During the production and storage of cyclosporine, impurities can develop that must be carefully monitored to ensure the medication’s safety and efficacy. Regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) provide guidelines for acceptable impurity levels in pharmaceutical products.

Cyclosporine is not an antibiotic. It is an immunosuppressant classified as a calcineurin inhibitor. It works by reducing the activity of immune cells, particularly T-lymphocytes, to prevent the body’s immune system from attacking transplanted organs or tissues in autoimmune conditions. Unlike antibiotics, which fight bacterial infections, cyclosporine modulates the immune response.
Common side effects of cyclosporine include high blood pressure, kidney dysfunction, tremors, increased hair growth (hirsutism), and gum overgrowth (gingival hyperplasia). Long-term use may increase the risk of serious conditions such as infections, liver dysfunction, and lymphoma due to its immune-suppressing effects. Regular monitoring is essential to manage these risks.
No, cyclosporine is not a corticosteroid. It is an immunosuppressant that works by inhibiting calcineurin, an enzyme involved in activating immune cells. Corticosteroids, like prednisone, reduce inflammation by mimicking the hormone cortisol, whereas cyclosporine directly modulates immune cell activity.
