About the Study

Cyclosporine, commonly known as cyclosporine or cyclosporin, is an immune suppressant drug that inhibits calcineurin. It's a completely natural product. It is used to treat rheumatoid arthritis, psoriasis, Crohns disease, nephrotic syndrome, and to avoid organ rejection in organ transplant recipients. It's also used to treat kerato conjunctivitissicca as an eye drop (dry eyes). High blood pressure, headaches, kidney issues, excessive hair growth, and vomiting are all common adverse effects. An increased chance of infection, liver issues, and lymphoma are among the other serious side effects. To reduce the possibility of side effects, blood levels of the medicine should be monitored. Cyclosporin use during pregnancy may cause preterm birth, but it does not appear to cause birth abnormalities. Cyclosporine suppresses the immune system, preventing white blood cells from attempting to remove the transplanted organ. Patients with severe rheumatoid arthritis who have failed to respond to methotrexate are given cyclosporine [1].

Tacrolimus is a macrolide antibiotic and cyclosporine is a lipophilic cyclic peptide of eleven amino acids. These medicines are fungi-derived and have similar suppressive effects on cellmediated and humoral immune responses. Both medications bind to a class of cytoplasmic proteins found in most cells: cyclophilins in the case of cyclosporine and FK-binding proteins in the case of tacrolimus. The drug-receptor complex binds to and inhibits calcineurin, a calcium- and calmodulin-dependent phosphatase, in a particular and competitive manner. Interleukin (IL)-2, Tumour Necrosis Factor (TNF)-alpha, IL-3, IL-4, CD40L, granulocyte-macrophage colony-stimulating factor, and interferon-gamma transcriptional activation is reduced as a result of this process, which suppresses the translocation of a family of Transcription Factors (NF-AT). T lymphocyte proliferation is eventually inhibited. Numerous authors have been investigated in the cyclosporine potential host action, including CsA suppresses T cell activation by limiting the transcription of cytokine genes such as IL-2 and IL-4, according to early biological investigations. CsA binds to cyclophilins with high affinity after it enters T cells, particularly the cytosolic 17 kDa cyclophilin A, which is the most common cyclophilin in T cells. Cyclophilins are cytosolic proteins that have peptidyl-proline-cis-trans isomerase activity, which may be involved in protein folding [2]. Though CsA reduces cyclophilin PPIase activity, this inhibition is not included in the immunosuppressive process because other CsA analogues that do not impede T cell activation can still decrease PPIase activity. The cyclophilin–CsA complex, but really not cyclophilin itself can bind to calcineurin, a cytosolic protein. Calcineurin, also known as PP2B, is a protein serine threonine phosphatase whose activity is strictly controlled by Ca² calmodulin.

Calcineurin dephosphorylates individuals of the NFAT family, needed to enter the nucleus and trigger gene expression via the NF-AT cis-element. Recent research has discovered that activated calcineurin also translocates into the nucleus with NFAT family members, where it may help to keep NFAT proteins active. NFAT1, NFAT2, and NFAT4 are all involved in the transcriptional activation of genes that encode cytokines including IL-2 and IL-4, as well as CD40L. CsA inhibits nuclear translocation of these NFAT family members and consequent gene expression in activated T cells by blocking their calcineurinmediated dephosphorylation. The calcineurinr NFAT pathway is undoubtedly one of the mechanisms of CsA-mediated immunosuppression. Since its beginning clinical usage in the late 1970s, cyclosporine has undoubtedly transformed transplant therapy, improving rates of acute rejection and early graft survival. Despite the early discovery of acute and more recently suspected chronic nephrotoxicity, the use of cyclosporine in transplant therapy remains a mainstay. While the evidence is promising, none of it appears to be sufficient to replace chronic calcineurin as a medication for transplant acceptance prevention [3,4].

Tremor, headache, dizziness, abnormal hair growth, nausea or vomiting, diarrhea, stomach upset can occur. If any of these effects persist or worsen, consult health care professionals before if shows higher impact on others body parts. Abnormal growth and swelling of the gums can occur. Brush your teeth and apply dental floss daily to reduce this problem. This medicine can raise your blood pressure. Check your blood pressure regularly and let your doctor know if the result is too high [5]. If you have serious side effects such as: Signs of kidney problems (e.g., changes in the amount of urine that has passed), signs of liver problems (e.g., nausea, vomiting persists, dark urine, yellow eyes, weird skin, Stomach or abdominal pain), bruising, bleeding, abnormal fatigue, weakness, cramps, slow and irregular heartbeat, numbness, tingling of the skin, severe lower limb pain do not neglect to approach the health care professionals for better treatment [6]. Try to avoid using this Cyclosporine if you are having Skin lesions of unknown cases or any other infections.
