Barigen 4 mg, also known as Baricitinib, is a medication primarily prescribed for the treatment of rheumatoid arthritis (RA). It belongs to a class of drugs called Janus kinase (JAK) inhibitors, which work by blocking specific enzymes involved in the inflammatory process. By reducing inflammation, Barigen helps alleviate symptoms such as joint pain, swelling, and stiffness associated with RA. It is typically used in patients who have not responded well to other treatments. As with any medication, Barigen 4 mg should be taken under medical supervision, and potential side effects should be monitored closely.
