Baricitinib

Baricitinib is a prescription medication used to treat adults with moderately to severely active rheumatoid arthritis (RA). It is used in combination with methotrexate, an arthritis medication. Baricitinib belongs to a class of drugs called Janus kinase inhibitors, which work by blocking certain proteins that contribute to inflammation. Common side effects include upper respiratory tract infection, headache, and back pain.

Baricitinib, sold under the brand name Olumiant, is a prescription medication classified as a Janus kinase (JAK) inhibitor. It is used to treat several conditions, including:

Approved uses:

• Rheumatoid arthritis (RA): In adults who have not responded adequately to one or more tumor necrosis factor (TNF) inhibitor medications. RA is an autoimmune disease that causes chronic inflammation and pain in the joints.
• COVID-19: In hospitalized adults who require supplemental oxygen, mechanical ventilation, or extracorporeal membrane oxygenation (ECMO), a technique that supports the lungs and heart during severe illness.
• Alopecia areata: In adults with moderate to severe cases of this autoimmune disease that causes hair loss.

Mechanism of action:

Baricitinib works by inhibiting the activity of JAK enzymes, which are involved in the signaling pathways of the immune system. By suppressing these pathways, Baricitinib helps to reduce inflammation associated with various conditions, including RA, COVID-19, and alopecia areata.

Availability and forms:

• Baricitinib is typically available as tablets for oral administration.
