Leukotriene receptor antagonism may not be effective in atopic dermatitis treatment after all

What is known and ObjectiveLiterature evidence suggests leukotriene involvement in the pathogenesis of atopic dermatitis. This article aimed to discuss whether the off-label use of montelukast, a leukotriene receptor antagonist, is justifiable for the treatment of atopic dermatitis. CommentMost non-randomized studies supported the use of montelukast for atopic dermatitis treatment. However, evidence from these studies should be interpreted with caution as it is relatively weak due to the absence of randomization, control groups and blinding processes, subjecting the results to high risk of selection and reporting biases. The inconsistent findings across RCTs may be related to the limited number of patients, nuances in study designs, varying severity of disease and the concomitant use of steroids in some of the studies. What is new and ConclusionCurrent literature evidence is limited to rationally support the use of montelukast in atopic dermatitis treatment. For now, the conventional treatments should be preferred in the clinical setting.
