Tacrolimus 0.1 Ointment/Tacrolimus (also FK-506 or Fujimycin) is an immunosuppressive drug whose main use is after an 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. It was discovered in 1984 from the fermentation broth of a Japanese soil sample that contained the bacteria Streptomyces tsukubaensis. Tacrolimus is chemically known as a macrolide. It reduces peptidyl-prolyl isomerase activity by binding to the immunophilin FKBP-12 (FK506 binding protein) creating a new complex. This FKBP12-FK506 complex inhibits calcineurin which inhibits T-lymphocyte signal transduction and IL-2 transcription.
Tacrolimus (anhydrous) is tacrolimus is a macrolide containing a 23-membered lactone ring, originally isolated from the fermentation broth of a Japanese soil sample that contained the bacteria Streptomyces tsukubaensis. It has a role as an immunosuppressive agent and a bacterial metabolite.

Mechanism of Action of Tacrolimus
The mechanism of action of tacrolimus in atopic dermatitis is not known. While the following have been observed, the clinical significance of these observations in atopic dermatitis is not known. It has been demonstrated that tacrolimus inhibits T-lymphocyte activation by first binding to an intracellular protein, FKBP-12. A complex of tacrolimus-FKBP-12, calcium, calmodulin, and calcineurin is then formed and the phosphatase activity of calcineurin is inhibited. This prevents the dephosphorylation and translocation of the nuclear factor of activated T-cells (NF-AT), a nuclear component thought to initiate gene transcription for the formation of lymphokines. Tacrolimus also inhibits the transcription of genes that encode IL-3, IL-4, IL-5, GM-CSF, and TNF-, all of which are involved in the early stages of T-cell activation. Additionally, tacrolimus has been shown to inhibit the release of pre-formed mediators from skin mast cells and basophils and to downregulate the expression of FceRI on Langerhans cells.

Tacrolimus is a macrolide immunosuppressant produced by Streptomyces tsukubaensis. Tacrolimus is commercially available for topical use as a 0.03 or 0.1% ointment. The exact mechanism(s) of action of tacrolimus in the treatment of atopic dermatitis has not been elucidated but appears to involve inhibition of the activation of T cells. Tacrolimus also has been shown to inhibit the release of mediators from skin mast cells and basophils and to downregulate the expression of high-affinity receptors for immunoglobulin E (IgE) on Langerhans cells. Although tacrolimus is not genotoxic and does not interact directly with DNA, the drug may impair local immunosurveillance.
Indications of Tacrolimus
- For use after an allogeneic organ transplant to reduce the activity of the patient’s immune system and so the risk of organ rejection. It was given FDA approval in 1994 for use in liver transplantation. Since then, this indication has expanded to kidney, heart, small bowel, pancreas, lung, trachea, skin, cornea, and limb transplants. It has also been used in a topical preparation in the treatment of severe atopic dermatitis.
