Folitrax contains Methotrexate, which is a disease-modifying anti-rheumatic drug (DMARD) and also a chemotherapy agent.
It is used in low doses for autoimmune diseases (like arthritis) and in higher doses for some cancers.

Mechanism 

• Methotrexate blocks an enzyme called dihydrofolate reductase (DHFR).

• This stops the making of DNA, RNA, and proteins that cells need to grow.

• In cancer, it slows down rapidly dividing tumor cells.

• In autoimmune diseases, it reduces overactive immune system activity.
