If topical corticosteroids and moisturisers fail, short-term treatment with topical calcineurin inhibitors such as tacrolimus or pimecrolimus may be tried, although their use is controversial, as some studies indicate that they increase the risk of developing skin cancer or lymphoma. A 2007 meta-analysis showed that topical pimecrolimus is not as effective as corticosteroids and tacrolimus. A 2015 meta-analysis, though, indicated that topical tacrolimus and pimecrolimus are more effective than low-dose topical corticosteroids, and found no evidence for increased risk of malignancy or skin atrophy. In 2016, crisaborole, an inhibitor of PDE-4, was approved as a topical treatment for mild-to-moderate eczema.Other medications used for AD include systemic immunosuppressants such as ciclosporin, methotrexate, interferon gamma-1b, mycophenolate mofetil, and azathioprine. Antidepressants and naltrexone may be used to control pruritus (itchiness). Leukotriene inhibitors such as monteleukast are of unclear benefit as of 2018.In 2017, the monoclonal antibody(mAb) dupilumab under the trade name Dupixent was approved to treat moderate-to-severe eczema. In 2021, an additional monoclonal antibody, tralokinumab, was approved in the EU & UK with the trade name Adtralza then later in the US as Adbry for similarly severe cases.

He examined the prevalence of uterine contractions throughout pregnancy and determined that contractions that do not lead to labor are a normal part of pregnancy. == References ==
