What conditions require taking cyclosporine?

Cyclosporine is an immunosuppressive agent available in various formulations such as capsules, eye drops, and injectables. Clinically, it is used in the treatment of conditions including Sjögren's syndrome, dermatomyositis, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus, but must be taken under medical supervision. Specific details are as follows:

1. Sjögren's syndrome: This is an autoimmune disorder typically characterized by dryness of the eyes and mouth. Cyclosporine helps alleviate symptoms and improve patients' quality of life.

2. Dermatomyositis: Dermatomyositis is a chronic autoimmune disease in which the immune system attacks the body's muscle and skin tissues. As an immunosuppressant, cyclosporine can suppress immune system activity, reduce attacks on muscles and skin, thereby alleviating inflammatory responses, controlling disease progression, and reducing associated symptoms.

3. Psoriasis: Psoriasis is a chronic skin condition in which an overactive immune system causes excessive skin cell growth and inflammation in the epidermal layer. By suppressing immune system activity, cyclosporine reduces excessive inflammatory responses and abnormal proliferation of skin cells, thus improving psoriasis symptoms and preventing disease progression.

4. Rheumatoid arthritis: Rheumatoid arthritis is a chronic inflammatory joint disease in which the immune system attacks joint tissues, leading to joint inflammation and pain. Cyclosporine suppresses immune system function, reduces immune attacks on joint tissues, decreases the severity of joint inflammation and pain, and improves symptoms of rheumatoid arthritis.

5. Systemic lupus erythematosus: This is an autoimmune disease in which the immune system attacks the body's tissues and organs, including the skin, joints, kidneys, and others. Cyclosporine reduces immune-mediated damage to tissues, thereby alleviating inflammatory responses and organ damage, helping control symptoms and disease progression in systemic lupus erythematosus.

Patients are advised to take medication strictly as prescribed, seek timely medical attention if adverse reactions occur, and undergo standardized treatment under a physician’s guidance, which contributes to recovery.
