Topical calcineurin inhibitors in the treatment of atopic dermatitis - an update on safety issues.

Atopic dermatitis is a common chronic skin disorder whose management is complex. Topical corticosteroids have been the mainstay of atopic dermatitis treatment for more than 50 years but have multiple side effects. Topical calcineurin inhibitors including tacrolimus and pimecrolimus are safe and efficacious in atopic dermatitis. In 2005 the FDA issued "black box" warnings for pimecrolimus cream and tacrolimus ointment because of potential safety risks, including skin cancers and lymphomas. However, these concerns are not supported by current data. Topical calcineurin inhibitors are particularly indicated for treating patients with atopic dermatitis in whom topical corticosteroid therapy cannot be employed or may cause irreversible side effects. They can be used advantageously in problem zones. A novel regimen of proactive treatment has been shown to prevent, delay and reduce exacerbations of atopic dermatitis. Therapy with topical calcineurin inhibitors should be managed by an experienced specialist and each patient should receive proper education on how to use them and what possible unwanted effects may be expected.
