Tacrolimus is a "macrolide isolated from the culture broth of a strain of Streptomyces tsukubaensis that has strong immunosuppressive activity in vivo and prevents the activation of T-lymphocytes in response to antigenic or mitogenic stimulation in vitro."[1] It is a calcineurin inhibitor. Originally used as an antirejection drug in organ transplantation, it has been found useful in other medicial applications.[2]

Approved indications include therapy for Crohn's disease, and, in drug-eluting stents, as a means of preventing reocclusion after blood vessel revascularization. In topical form, it has been approved for atopic dermatitis.
