Atopic dermatitis is a chronic (long-lasting) disorder of skin in which the skin becomes inflamed, causing itchiness, redness, swelling, cracking, weeping, crusting, and scaling. The inflammation is caused by activation of the immune system although the reason behind the activation remains unknown. Tacrolimus ointment suppresses the immune system and also the inflammation by inhibiting an enzyme (calcineurin) crucial for the multiplication of T-cells, cells which are needed for activation of the immune system.
How can tacrolimus ointment work?
Tacrolimus ointment works on the immune system and directly on skin tissues. It binds to a receptor within the cell referred to as the FK binding proteins. This resulting drug-protein complex inhibits calcineurin which in turn reduces the activity of t-lymphocytes in the immune system.
As a consequence, t cells fail to release their cytokines (that causes inflammation, redness and itching). It seems to reduce the number of all il8 cytokine receptors on the keratinocyte, hence reducing inflammation.
