What is tacrolimus ointment, and how does it work (mechanism of action)?
Tacrolimus ointment is a topical drug (a drug that is applied to the skin) that is used for the treatment of atopic dermatitis (eczema). Atopic dermatitis is a chronic (long-lasting) disease 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 though the reason for the activation is unknown. Tacrolimus ointment suppresses the immune system and the inflammation by inhibiting an enzyme (calcineurin) crucial for the multiplication of T-cells, cells that are required for activation of the immune system.
