Cyclosporine belongs to a class of medications known as immunosuppressants.Cyclosporine is used to prevent organ rejection in people who have had a liver, kidney or heart transplant. It is usually taken along with other medications to make your new organ function normally. It is also used in rheumatoid arthritis and psoriasis.
Mechanism of action
Cyclosporine binds to cyclophilin. The complex then inhibits calcineurin, which is normally responsible for activating the transcription of interleukin 2. Cyclosporine also inhibits the production of lymphokines and the release of interleukin. In ophthalmic applications, the exact mechanism of action is unknown. It is believed that the cyclosporin emulsion acts as a partial immunomodulator in patients whose production of tears due to ocular inflammation associated with keratoconjunctivitis sicca is suppressed.
