What is Abrocitinib and its mechanism of action?

Abrocitinib is a film-coated tablet whose active ingredient is abrocitinib. It belongs to a class of drugs known as Janus kinase inhibitors, primarily working to help reduce inflammation in the body. Specifically, abrocitinib reduces the activity of an enzyme called "Janus kinase", which plays a key role in the inflammatory process. By inhibiting the activity of this enzyme, abrocitinib can effectively reduce skin itching and inflammation, thereby improving the patient's overall condition. This medicine is subject to additional monitoring to quickly obtain new safety information, and patients are also encouraged to report any side effects that occur.

Uses and suitable population for Abrocitinib

Abrocitinib is used to treat adults and adolescents aged 12 years and older with moderate to severe atopic dermatitis (also known as atopic eczema). In addition to reducing skin itching and inflammation, abrocitinib can also reduce sleep disturbances, anxiety, or depression caused by atopic eczema, and significantly improve patients' quality of life. It is important to note that this medicine has not been approved for use in children under 12 years of age, as the safety and benefits in this age group have not been established.

Important safety warnings before starting treatment

Before starting abrocitinib, you must tell your doctor if you have any infections or if you frequently get infections. Because abrocitinib may lower your body's ability to fight infections, worsen existing infections, or increase the risk of new infections. If you have diabetes or are older than 65 years, your risk of infection is higher. Your doctor will monitor your condition through blood tests before and during treatment and adjust the treatment plan based on the results. In addition, patients will receive a patient card containing important safety information, which should be carried at all times.
