Role of janus kinase inhibitors in the treatment of alopecia areata
July 2018
in “Drug design, development and therapy”
TLDR Janus kinase inhibitors show promise in treating alopecia areata but need better topical formulations.
Alopecia areata (AA) is a common hair loss disorder with no FDA-approved treatments, and current off-label options have limited efficacy. Advances in molecular biology have led to the development of targeted therapies, including janus kinase inhibitors (JAKis), which suppress T-cell-mediated inflammatory responses. Studies on JAKis such as tofacitinib, ruxolitinib, and baricitinib have shown promising results in treating AA. However, topical formulations of these drugs have not been as effective and need further improvement. This review summarized the evidence on the efficacy and safety of JAKis for AA treatment.
