Can ritexitinib be taken long-term?

Ritlecitinib is an oral, selective Januskinase3(Januskinase span>JAK3) and TEC family kinase inhibitors, mainly used to treat alopecia areata (Alopecia Areata). As an immunomodulator, its main function is to suppress overactive immune cells in the immune system, thereby reducing the attack on hair follicles and promoting hair regeneration. Long-term use of ritixitinib may be necessary for many patients, but suitability for long-term use needs to be assessed on an individual basis.

Clinical studies have shown that patients can achieve better hair recovery with continued medication. However, whether long-term use is appropriate requires a comprehensive judgment based on the patient's disease progression, drug effects, and side effects.
