I. Introduction
Brief Overview of Cyclosporin
Cyclosporin, a medication that suppresses the system, has played a crucial role, in modern medicine by significantly improving the outcomes of organ transplants and helping to effectively treat autoimmune disorders.
Importance in Medical Treatment
The impact of Cyclosporin in treatments is enormous. It has applications from improving survival rates after organ transplantation to regulating autoimmune responses.
Objective of the Article
This article intends to shed light on the facets of Cyclosporin, including its mechanism of action and its wide range of applications, in the field of medicine.
II. What is Cyclosporin?
Chemical Composition
Cyclosporin is a type of polypeptide composed of 11 amino acids. It falls under the category of calcineurin inhibitors. It has a complex molecular structure.
Medicinal Properties
Cyclosporin has immunosuppressive properties from a pharmacological standpoint. It works by blocking the calcineurin pathway, which affects the activation of T lymphocytes.
Historical Background
Cyclosporin, which was derived from the fungus Tolypocladium inflatum and first discovered in the 1970s, brought about a significant change, in organ transplantation procedures. It made possible what was previously considered to be a feat.
III. How Cyclosporin Works
Mechanism of Action
The drug works by attaching to a protein called cyclophilin in T lymphocytes. This combination then blocks the action of calcineurin, ultimately hindering T cells' activation and growth.
Target Areas in the Body
Cyclosporin generally affects the system, particularly the lymphatic tissues circulating T cells and the calcineurin signaling pathways.
Medical Conditions it Affects
Rejection of organ transplants Disorders where the immune system attacks the body's cells and tissues Long-term inflammatory conditions that persist over time
IV. Approved Uses of Cyclosporin
Organ Transplantation
Kidney Transplants
Cyclosporine is a medication that is used to prevent the body from rejecting a transplanted organ, such as a kidney, liver, or heart. It belongs to a group of medicines known as immunosuppressive agents12. Cyclosporine has been effective in significantly lowering the rates of graft rejection among individuals who have undergone kidney transplantation34. Cyclosporine can cause serious side effects, including kidney failure or life-threatening infection, so it requires frequent blood tests and dose adjustments to avoid toxicity or organ rejection152.

Liver Transplants
In the field of liver transplantation it reduces the intensity and occurrence of long term rejection incidents.
Heart Transplants
The drug plays a role in the protocols, for heart transplants as it ensures the viability of the graft and the survival of the patient.
Autoimmune Disorders
Rheumatoid Arthritis
Cyclosporin, also known as Ciclosporin, is a medicine that suppresses immune system function and is used to treat autoimmune conditions such as rheumatoid arthritis (RA) and psoriasis. It can reduce pain, swelling, and stiffness in rheumatoid arthritis, and is also used to treat a number of other autoimmune and inflammatory conditions, including psoriatic arthritis and lupus12. Cyclosporin is a long-term treatment that may take up to four months before you notice the benefits13. Cyclosporin can cause serious side effects, such as kidney failure or infection, requiring regular blood tests and dose adjustments142.

Psoriasis
Cyclosporin is an immunosuppressive drug that was first used to help prevent rejection in organ transplant patients. It is also used to treat severe plaque psoriasis, usually when other treatments have not been successful12. Cyclosporin can provide rapid relief from symptoms, and some improvement may be seen after two weeks of treatment13. However, cyclosporin can cause serious side effects, such as kidney damage, high blood pressure, infection, and increased risk of skin cancer123. Therefore, it requires regular monitoring and dose adjustment by a dermatologist2.

Eye Conditions
Dry Eyes
Cyclosporin is a calcineurin inhibitor immunosuppressant that can increase tear production in patients with dry eye, especially those with Sjögren’s syndrome, a chronic inflammatory disorder that affects the lacrimal and salivary glands12. Cyclosporin can be applied as an ophthalmic solution (such as CEQUA) to reduce inflammation and improve vision in patients with moderate-to-severe dry eye disease13. However, cyclosporin may cause side effects such as burning, stinging, redness, or blurred vision, and it may take several months to achieve optimal results13. Therefore, it should be used under the guidance of an eye care provider24.

V. Off-Label Uses of Cyclosporin
Dermatological Conditions
Eczema
Cyclosporin is an immunosuppressant drug that was originally developed to prevent organ rejection in transplant patients. It can also be used off-label to treat severe eczema that does not respond well to topical therapies alone. Cyclosporin works by lowering the inflammatory cytokine production, which is a chemical messenger that activates the immune system and causes inflammation in the skin12. However, cyclosporin is not a cure for eczema, and the symptoms may return when the treatment is stopped. Cyclosporin may also cause serious side effects such as kidney damage, high blood pressure, increased risk of infection, and increased risk of cancer13. Therefore, it should be used with caution and under the supervision of a dermatologist24.

Alopecia Areata
Cyclosporin is an immunosuppressant drug that can be used to treat alopecia areata, a condition that causes hair loss in patches. Cyclosporin may help to suppress the immune system’s attack on the hair follicles, which is thought to be the cause of alopecia areata12. Cyclosporin can be used alone or in combination with systemic corticosteroids, which are another type of anti-inflammatory drug23. However, cyclosporin is not a cure for alopecia areata, and the hair loss may recur when the treatment is stopped. Cyclosporin may also cause serious side effects such as kidney damage, high blood pressure, increased risk of infection, and increased risk of cancer12. Therefore, it should be used with caution and under the guidance of a dermatologist23.
