Upadacitinib is a medication used in the treatment of several inflammatory conditions. It is classified as a Janus kinase inhibitor, which works by interfering with the signaling pathways that lead to inflammation.
Mechanism of Action[edit | edit source]
Upadacitinib functions by selectively inhibiting the activity of Janus kinase (JAK) enzymes. These enzymes are crucial in the signaling pathways of various cytokines and growth factors that are involved in hematopoiesis and immune function. By inhibiting JAKs, upadacitinib reduces the inflammatory response that is characteristic of autoimmune diseases.
Medical Uses[edit | edit source]
Upadacitinib is primarily used in the treatment of:
Rheumatoid Arthritis[edit | edit source]
In patients with moderate to severe rheumatoid arthritis, upadacitinib is used to reduce symptoms and improve physical function. It is often prescribed when patients have had an inadequate response to one or more disease-modifying antirheumatic drugs (DMARDs).
Psoriatic Arthritis[edit | edit source]
For individuals with active psoriatic arthritis, upadacitinib helps in reducing joint pain and swelling, as well as improving skin symptoms associated with the condition.
Atopic Dermatitis[edit | edit source]
Upadacitinib is also indicated for the treatment of moderate to severe atopic dermatitis in adults and adolescents who are candidates for systemic therapy.
Ulcerative Colitis[edit | edit source]
In the context of ulcerative colitis, upadacitinib is used to induce and maintain clinical remission in patients with moderate to severe disease.
Side Effects[edit | edit source]
Common side effects of upadacitinib include:
Serious side effects may include:
- Increased risk of serious infections
- Thrombosis
- Liver enzyme elevations
Administration[edit | edit source]
Upadacitinib is administered orally, typically once daily. The dosage may vary based on the specific condition being treated and the patient's response to the medication.
