Tacrolimus is an immunosuppressant. It works by decreasing your body's immune system. Tacrolimus topical (for the skin) is used to treat severe atopic dermatitis (eczema). Tacrolimus may also be used for purposes not listed in this medication guide.
How does tacrolimus affect the kidneys?
Tacrolimus is a medicine that lowers the body's natural immunity. The immune system is thought to be involved in a disorder which causes the kidneys to leak protein into the urine (Nephrotic Syndrome). It is widely used to prevent rejection of transplanted organs, such as the kidney, heart, and liver
Function&Application
Tacrolimus is used on the skin to treat a skin condition called eczema (atopic dermatitis) in patients who have not responded well to (or should not use) other eczema medications.
Eczema is an allergic-type condition that causes red, irritated, and itchy skin. This drug works by weakening the skin's defense (immune) system, thereby decreasing the allergic reaction and relieving the eczema. Tacrolimus belongs to a class of drugs known as topical calcineurin inhibitors (TCIs).
Tacrolimus is an immunosuppressive drug whose main use is after organ transplant to reduce the activity of the patient's immune system and so the risk of organ rejection. It is also used in a topical preparation in the treatment of severe atopic dermatitis, severe refractory uveitis after bone marrow transplants, and the skin condition vitiligo.
Tacrolimus is chemically known as a macrolide. It reduces peptidyl-prolyl isomerase activity by binding to the immunophilin FKBP-12 creating a new complex. This FKBP12-FK506 complex inhibits calcineurin which inhibits T-lymphocyte signal transduction and IL-2 transcription.
Tacrolimus (also FK-506 or Fujimycin) is an immunosuppressive drug whose main use is after organ transplant to reduce the activity of the patient's immune system and so the risk of organ rejection. It is also used in a topical preparation in the treatment of severe atopic dermatitis, severe refractory uveitis after bone marrow transplants, and the skin condition vitiligo. Tacrolimus was first extracted from the fermentation broth of Streptomyces tsukuba, a soil microbe found in Tsukuba, Japan.1 The name tacrolimus is derived by taking the 't' for Tsukuba, the name of the mountain where the soil sample was extracted, 'acrol' for macrolide and 'imus' for immunosuppressant. Although structurally unrelated to cyclosporin, tacrolimus shows a similar spectrum of immunosuppressive effects to this agent at the cellular and molecular level. Initial studies indicated that tacrolimus was a powerful immunosuppressant, displaying approximately 100-fold greater in vitro potency than cyclosporin in inhibiting T cell activation. Subsequent in vivo studies have shown tacrolimus to be effective both in suppressing spontaneous and experimental autoimmune disease, and in preventing allograft and xenograft rejection in animal models of organ transplantation.
Initially, tacrolimus was used for systemic immunosuppression of patients who had undergone allograft transplants to stop them from rejecting their new grafts. Soon, however, through the benefit of the serendipity of science, it was noticed that tacrolimus could produce favorable results in skin disorders in some of the patients who had undergone transplantation. The discovery of tacrolimus has thus lead to greater understanding of skin pathology, for example of atopic dermatitis. Subsequently, other topical applications of tacrolimus were reported and the use of this agent in dermatology is gradually expanding.
