Description:

Cyclosporin A is an immunosuppressant drug that binds cyclophilin D, inhibiting the phosphatase activity of calcineurin in T cells.1,2,3 It blocks the transcription of genes involved in T cell activation by interfering with the calcineurin-driven nuclear import of the transcription factor NFAT.1,4,5 Because of its powerful immunosuppressant activity, cyclosporin A has long been used for the prevention of transplant rejection.

Medical uses:

Ciclosporin is approved by the FDA to treat and prevent graft-versus-host disease in bone marrow transplantation and to prevent rejection of kidney, heart, and liver transplants.It is also approved in the US for treating of rheumatoid arthritis and psoriasis, persistent nummular keratitis following adenoviral keratoconjunctivitis,and as eye drops for treating dry eyes caused by Sjögren's syndrome and meibomian gland dysfunction.

In addition to these indications, ciclosporin is also used in severe atopic dermatitis, Kimura disease, pyoderma gangrenosum, chronic hives, acute systemic mastocytosis, and posterior or intermediate uveitis with noninfective cause.It is also used, albeit infrequently, in severe rheumatoid arthritis and related diseases.

Ciclosporin has also been used in people with acute severe ulcerative colitis and hives that do not respond to treatment with steroids.
