Upadacitinib

Upadacitinib is a prescription medication used to treat certain inflammatory conditions, such as rheumatoid arthritis. It works by selectively blocking a specific enzyme called Janus kinase 1 (JAK1), which plays a role in the body's immune response. By inhibiting JAK1, upadacitinib helps reduce inflammation, pain, and joint damage. It is taken orally, usually once daily, and is intended for use when other treatments haven't been effective. Like all medications, it may have side effects and should be used under medical supervision to ensure safety and effectiveness.
