What is methotrexate used for?

How does methotrexate work?

How does methotrexate work?

methotrexate is an antimetabolite medication that treats many types of cancers and non-cancer conditions (like arthritis and psoriasis). For cancer: TREXALL works by blocking dihydrofolate reductase, a protein in your body that’s important for making DNA in cells and for cell growth. Since cancer cells grow much more quickly than healthy cells, the medication helps slow down cancer growth so the cancer can’t spread as well.

For non-cancer conditions: We don’t know exactly how TREXALL works to treat non-cancer conditions such as rheumatoid arthritis and psoriasis. But research suggests that, at lower doses, it blocks the immune system from becoming too active. For psoriasis, the medication might also help slow down the growth of skin cells.

Effects of other drugs, drug classes and over-the-counter products on methotrexate

Effects of other drugs, drug classes and over-the-counter products on methotrexate

The following medications may interact with methotrexate:

  • Concomitant administration of some NSAIDs with high dose methotrexate therapy has been reported to elevate and prolong serum methotrexate levels, resulting in deaths from severe hematologic and gastrointestinal toxicity
  • methotrexate is partially bound to serum albumin, and toxicity may be increased because of displacement by certain drugs, such as salicylates, phenylbutazone phenytoin, and sulfonamides. Renal tubular transport is also diminished by probenecid; use of methotrexate with this drug should be carefully monitored
  • Oral antibiotics such as tetracycline, chloramphenicol, and nonabsorbable broad spectrum antibiotics, may decrease intestinal absorption of methotrexate or interfere with the enterohepatic circulation by inhibiting bowel flora and suppressing metabolism of the drug by bacteria
  • Penicillins may reduce the renal clearance of methotrexate; increased serum concentrations of methotrexate with concomitant hematologic and gastrointestinal toxicity have been observed with methotrexate. Use of methotrexate with penicillins should be carefully monitored
