Full Answer
Corticosteroids, such as prednisone, are among the most common immunosuppressants that healthcare providers prescribe. But there are many types of immunosuppressants. Your provider will select a medicine (or a combination of immunosuppressants) based on your specific condition and symptoms.
You may need to take immunosuppressants for years until the new immune system settles down.
Immunosuppressants. Immunosuppressants stop your immune system from damaging healthy cells and tissues. People with organ transplants and stem cell transplants take these medicines to prevent transplant rejections. The drugs also treat autoimmune disease symptoms. Immunosuppressants are powerful drugs that require careful monitoring ...
The body’s immune system helps fight off infections that cause illness. But sometimes, the immune system mistakenly attacks healthy cells and tissues. Immunosuppressants can slow or stop this response.
The immune system essentially turns against the body and attacks it. Depending on which part of the body is under attack, this response can lead to different types of autoimmune diseases.
You’ll get more frequent blood tests to monitor drug effectiveness and side effects. Your healthcare provider may increase or decrease the dosage depending on symptoms and side effects.
You may receive immunosuppressants as a pill or liquid, IV or injection (shot). Types of immunosuppressants include:
Organ transplant patients take immunosuppressive drugs to prevent the rejection of the transplanted organ (graft) by their own body’s immune system. The immune system considers the transplanted organ’s tissues as foreign bodies and attacks them, leading to organ rejection.
Drugs are used to suppress the immune system in organ transplant patients to keep their bodies from rejecting the new organ.
Immunosuppressive drugs can be classified by the three phases in immunosuppression therapy which are: Induction: Start of therapy immediately after transplant. Maintenance: Lifelong maintenance medication to prevent rejection. Anti-rejection: Drugs to treat transplant rejection.
A healthy immune system protects the body by detecting and destroying harmful microbes and/or body cell changes that can cause diseases . The immune system fights foreign organisms that enter the body with several types of white blood cells that circulate in ...
Various proteins (cytokines) and enzymes act as signals to activate the immune cells. The body also develops specific antibodies to pathogens. Most immune cells are produced in the bone marrow as stem cells and mature into different immune cells such as. Lymphocytes.
Calcineurin inhibitors bind to and inhibit the calcineurin enzyme which activates T-cells, a type of lymphocyte.
Because of the risks associated with underdosing, as well as the side effect profile of these drugs, monitoring drug levels is critical for several commonly used immunosuppressants. Additionally, many of the immunosuppressants activate CYP 3A4 and P-glycoprotein, further complicating management.
As acute rejection rates have diminished, the focus of immunosuppression has shifted from preventing acute rejection to maximizing long-term survival while minimizing the comorbidities associated with long-term immunosuppression (see below). Because of the risks associated with underdosing, as well as the side effect profile of these drugs , monitoring drug levels is critical for several commonly used immunosuppressants. Additionally, many of the immunosuppressants activate CYP 3A4 and P-glycoprotein, further complicating management
Myelosuppression is a major side effect, develops in 1-2 weeks, and is often dose-limiting. Other major concerns include hepatotoxicity and pancreatitis, both of which have limited its use. Mycophenolate mofetil is an inosine monophosphate dehydrogenase inhibitor which also impacts purine synthesis (like azathioprine).
Immunosuppression is lifelong and typically consists of two (or three) phases:
Azathioprine, the first immunosuppressant, was made available in 1962. The introduction of cyclosporine in 1983 significantly improved outcomes for non-renal organs such as heart, lung, liver and pancreas transplants. The modern approach to immunosuppression takes into account the organ being transplanted (which have different pharmacologic requirements), characteristics of the recipient (e.g. whether or not they are pre-sensitized, or whether or not they have received a blood-compatible organ), and blend different immunosuppressants in an effort to produce synergy while minimizing harmful side effects. While great strides have been made in reducing the incidence of acute rejection, relatively little progress has been made with regards to long term graft survival. Immunosuppression is lifelong and typically consists of two (or three) phases:
Infection, malignancy, and organ dysfunction (e.g. renal or CNS toxicity) are the major concerns with long term immunosuppression.
Cyclosporine inhibits calcineurin, which reduces the production of IL-2 via inhibition of nuclear factor of activated T cells (NF-AT). Metabolized by CYP 3A4. Monitoring is essential although target levels are institution specific. Reasonable serum/plasma levels are 150-250 ng/mL at transplantation and 50-100 ng/mL at 3-6 months (or 100-300 and 80-200 ng/mL as measured in whole blood). Daily IV dosing is usually ~ 5 mg/kg in two divided doses, with PO dosing increased about 3-fold. Hypertension and renal injury are major side effects of this drug, neurotoxicity is also problematic.
Immunosuppressants are used for treating a wide variety of inflammatory and autoimmune diseases, as well as to prevent the rejection of tissues in organ transplant recipients. 1 .
Latesha Elopre, MD, MSPH. on May 20, 2021. Immunosuppression is the state in which your immune system is not functioning as well as it should. Immunosuppression can be caused by certain diseases but can also be induced by medications that suppress the immune system.
Medical Causes. Temporary immunosuppression can be caused by a variety of common infections, including influenza and mononucleosis, that weaken the immune response. However, when immune cells or other facets of the immune system are the targets of infection, severe immunosuppression can occur.
Monoclonal antibodies can also be used to prevent organ transplant rejection by preventing the body from launching an immune assault against the foreign tissues. 6
The immune system is made up of cells, tissues, and organs that help the body stave off infection. Without an intact immune system, infections that the body might otherwise be able to control can become serious and even fatal. Caiaimage / Sam Edwards / Getty Images.
Because steroids reduce inflammation, they are prescribed to treat a wide range of disorders, including: Allergies such as contact dermatitis, allergic rhinitis, and anaphylaxis. Autoimmune diseases like ulcerative colitis and Crohn's disease. Blood disorders like hemolytic anemia, lymphoma, and leukemia.

Immunosuppression is the suppression of the body’s immune system and its ability to fight infections and other diseases. Immunosuppression may be deliberately induced with immunosuppressant drugs, as in preparation for bone marrow or other organ transplantation, to prevent rejection of the donor tissue. Immunosuppression may also result from certain diseases such as AIDS or lymphoma or from anticancer drugs.
Sirolimus also is used sometimes to treat psoriasis.
Alemtuzumab is a recombinant humanized monoclonal antibody to human CD52 which is used in the therapy of chronic lymphocytic leukemia, and off-label for induction regimens for solid organ transplantation and for resistant or relapsing multiple sclerosis.
Tacrolimus (Astagraf XL, Envarsus XR, Prograf) also known as FK506, is a calcineurin inhibitor and potent immunosuppressive agent used largely to prevent rejection (attack of a transplanted organ by the immune system of a person receiving the organ) in people who have received a kidney transplant. Tacrolimus (Prograf) is also used along with other medications to prevent rejection in people who have received a liver or heart transplant. Tacrolimus is also sometimes used to treat fistulizing Crohn’s disease (a condition in which the body attacks the lining of the digestive tract, causing pain, diarrhea, weight loss, fever, and the formation of abnormal tunnels connecting the digestive tract to other organs or the skin).
