Cost-effectiveness of Tacrolimus Ointment Versus Pimecrolimus Cream in AdultsWith Atopic Dermatitis

Background: Tacrolimus 0.1% and pimecrolimus 1.0% are used for short-term and noncontinuous treatment of atopic dermatitis (AD) in patients unresponsive to conventional therapies.

Objective: To assess the cost-effectiveness of tacrolimus versus pimecrolimus in adults with AD.

Methods: Using a Markov cohort model, the authors projected clinical and economic outcomes over six weeks in adults receiving tacrolimus versus pimecrolimus. Cost-effectiveness was assessed in terms of the ratio of the expected cost of AD-related care to the expected number of days with resolved AD.

Results: Patients receiving tacrolimus had an estimated 4.9 fewer days with active AD over six weeks (30.0 versus 34.9 for pimecrolimus). Expected costs (per patient) of AD-related care also were lower for tacrolimus patients ($501.27 versus $546.14, respectively).

Limitation: While pimecrolimus is indicated for use solely in patients with mild-to-moderate AD, the trial on which this study was based included some patients with severe AD.

Conclusion: In adults with AD, tacrolimus 0.1% may yield better clinical outcomes and lower costs of care than pimecrolimus 1.0%.
