Immunosuppressive medicine, additionally called immunological disorder agents, immunosuppressants and antirejection medications square measure medicine that inhibit or forestall activity of the system. Immunosuppressive medicine are often classified into 5 groups:




•drugs working on immunophilins

•other medicine


In medical specialty (supraphysiologic) doses, glucocorticoids, like glucocorticoid, anti-inflammatory drug, and cortisol square measure accustomed suppress numerous allergic, inflammatory, and response disorders. They’re conjointly administered as posttransplantory immunosuppressants to stop the acute transplant rejection and graft-versus-host illness. Withal, they are doing not forestall AN infection and conjointly inhibit later reparative processes.

Immunosuppressive mechanism

Glucocorticoids suppress the cell-mediated immunity. They act by inhibiting genes that code for the cytokines lymphokine one (IL-1), IL-2, IL-3, IL-4, IL-5, IL-6, IL-8, and TNF-alpha, the foremost necessary of that is IL-2. Smaller protein production reduces the T cell proliferation.

Glucocorticoids additionally suppress the body substance immunity, inflicting B cells to precise smaller amounts of IL-2 and IL-2 receptors. This diminishes each B cell clone growth and protein synthesis.

Anti-inflammatory effects

Glucocorticoids influence every kind of inflammatory events, notwithstanding their cause. They induce the lipocortin-1 (annexin-1) synthesis, that then binds to cell membranes preventing the phospholipase A2 from coming back into contact with its substrate arachidonic acid. This results in diminished eicosanoid production. The enzyme (both Cox-1 and COX-2) expression is additionally suppressed, potentiating the result.

Glucocorticoids also stimulate the lipocortin-1 escaping to the extracellular area, wherever it binds to the white blood cell membrane receptors and inhibits numerous inflammatory events: animal tissue adhesion, emigration, chemotaxis, bodily function, metastasis burst, and therefore the unleash of assorted inflammatory mediators (lysosomal enzymes, cytokines, tissue urokinase, chemokines, etc.) from neutrophils, macrophages, and mastocytes.


Cytostatics inhibit organic process. In therapy, they're utilized in smaller doses than within the treatment of malignant diseases. They have an effect on the proliferation of each T cells and B cells. because of their highest effectiveness, purine analogs are most often administered.

Alkylating agents

The alkylating agents utilized in therapy are chemical element mustards (cyclophosphamide), nitrosoureas, Pt compounds, and others. Cyclophosphamide (Baxter's Cytoxan) is maybe the foremost potent immunological disorder compound. In little doses, it's very efficient within the medical care of systemic LE, response haemolytic anemias, granulomatosis with polyangiitis, and different immune diseases. High doses cause cytopenia and hemorrhagic cystitis.


Antimetabolites interfere with the synthesis of nucleic acids. These include:

• folic acid analogues, like immunosuppressive drug

• purine analogues, like medication and immunosuppressant

• pyrimidine analogues, like antimetabolite

• protein synthesis inhibitors.


Methotrexate may be a B-complex vitamin analogue. It binds dihydrofolate enzyme and prevents synthesis of tetrahydrofolate. it's utilized in the treatment of response diseases (for example rheumatism or Behcet's illness) and in transplantations.

Azathioprine and mercaptopurine

Azathioprine (Prometheus' Imuran), is that the main immunological disorder cytotoxic substance. it's extensively accustomed management transplant rejection reactions. it's nonenzymatically cleaved to immunosuppressant, that acts as a purine Analogue and an substance of deoxyribonucleic acid synthesis. immunosuppressant itself may also be administered directly.

By preventing the being growth of lymphocytes within the induction part of the immunologic response, it affects each the cell and therefore the body substance immunity. it's conjointly economical within the treatment of response diseases [1,2].

Cytotoxic antibiotics

Among these, dactinomycin is that the most vital. it's utilized in excretory organ transplantations. different cytotoxic antibiotics square measure anthracyclines, antibiotic C, bleomycin, antineoplastic antibiotic.


Immunosuppressive medicine square measure utilized in immunological disorder medical care to:

• Prevent the rejection of transplanted organs and tissues (e.g., bone marrow, heart, kidney, liver)

•Treat response diseases or diseases that square measure presumably of response origin (e.g., rheumatism, degenerative disorder, myasthenia, psoriasis, vitiligo, granulomatosis with polyangiitis, general LE, general sclerosis/scleroderma, pathology, focal segmental glomerulosclerosis, Crohn's disease, Behcet's Disease, pemphigus, spondylitis, and lesion colitis).

•Treat another non-autoimmune inflammatory diseases (e.g., future allergic respiratory disease control).

Side effects

A common side-effect of the many immunological disorder medicine is immunological disorder, as a result of the bulk of them act non-selectively, leading to enhanced status to infections and remittent cancer immunosurveillance. There are different side-effects, like cardiovascular disease, dyslipidemia, symptom, biological process ulcers, lipodystrophy, moon face, liver and excretory organ injury. The immunological disorder medicine conjointly act with different medicines and have an effect on their metabolism and action. Actual or suspected immunological disorder agents are often evaluated in terms of their effects on lymph cell subpopulations in tissues victimization assay.
