About
Tacrolimus is a calcineurin inhibitor used topically to treat moderate to severe atopic dermatitis (eczema) in adults and children who are not adequately responsive to or are intolerant of conventional therapies. It works by inhibiting T-lymphocyte activation, thereby reducing the inflammatory response in the skin. Unlike corticosteroids, tacrolimus does not cause skin atrophy, making it suitable for long-term use and application on sensitive areas like the face and skin folds.
Its mechanism involves binding to an intracellular protein, FKBP-12, and the resulting complex inhibits calcineurin, preventing the dephosphorylation and nuclear translocation of NF-AT, a transcription factor crucial for cytokine gene expression. This targeted action helps to manage chronic inflammatory skin conditions effectively while minimizing steroid-related side effects.
