Treating atopic dermatitis: tacrolimus seems to be effective and safe

Atopic dermatitis (atopic eczema) is a common skin condition that can have a big impact on the quality of life of both children and adults. I’ve been there, managing it for myself and for my children. We’ve been through wet wraps, preparations to put in the bath and to wash with; we’ve read about animals called Itchy and Scratchy who are supposed to make my child feel better about it all; and of course we’ve been through an awful lot of different creams. There are always two pressing questions, once you get onto medicated stuff, usually steroid creams – does it workand is it safe? Possible side effects, such as skin thinning, are quick to be mentioned.

A possible alternative to the topical corticosteroids (TCS) which form the mainstay of treating atopic dermatitis is tacrolimus ointment which, along with pimecrolimus, is from a class of drugs called topical calcineurin inhibitors. It comes in two strengths, 0.1% and 0.03%. Newer than corticosteroids, it is important to know about its effectiveness and safety. Concerns have been raised about an increased risk of cancers such as skin cancer and lymphomas, based on the possible risk of absorption into the blood stream, but this is controversial, with no strong supporting evidence.

Cochrane review has now been updated with the latest evidence from 20 randomized controlled trials with almost 6000 children and adults with moderate to severe atopic dermatitis, comparing topical tacrolimus with other active treatments. Previous research has shown that tacrolimus is better than placebo (a similar preparation without any drug). To find out as much as possible about side effects, the reviewers not only looked at data in the trials but also looked for other types of research, safety letters and industry warnings.
