Mechanism of action

Tacrolimus binds to FKBP12 and inhibits calcineurin phosphatase, preventing dephosphorylation and nuclear translocation of NFAT transcription factors. This blocks T-cell proliferation and the production of inflammatory cytokines (IL-2, TNF-α, IFN-γ) that drive atopic dermatitis and other inflammatory skin conditions. The topical formulation allows localized immunosuppression with reduced systemic exposure.
