Reditrex is used to treat rheumatoid arthritis, psoriasis, and certain types of cancer including leukemias and lymphomas. It may also be prescribed for other conditions as determined by a physician.
As an antimetabolite, Reditrex inhibits dihydrofolate reductase, an enzyme essential for DNA and RNA synthesis. This action suppresses rapidly dividing cells, including abnormal immune cells and cancer cells, reducing inflammation and disease progression.
Reditrex is a high-risk medication that requires regular blood monitoring for liver function, blood cell counts, and kidney function.
