Merex 500mg Injection inhibits dihydrofolic acid reductase. Therefore, this medicine interferes with DNA synthesis, repair, and cellular replication. Actively proliferating tissues such as malignant cells, bone marrow, fetal cells, buccal and intestinal mucosa, and urinary bladder cells are, in general, more sensitive to this medicine. Blocking these slows down how fast cancer cells grow, spread, and suppress the immune system in autoimmune diseases.
