Overview

  • Methotrexate is a medication used to treat cancer and autoimmune diseases like rheumatoid arthritis.
  • The video uses the movie "The Matrix" as an analogy to remember facts about methotrexate.

Mechanism of Action

  • Antifolate/Folate Antagonist: Methotrexate blocks folic acid signaling, stopping DNA replication and cell division.
    • Mnemonic: A director ripping a folder (folate) in frustration.

Uses

  • Cancer Treatment: Methotrexate is a chemotherapy agent that stops rapid cell division in cancer.
    • Mnemonic: A director eating buttery crab (symbolizing cancer).
  • Autoimmune Diseases: Used for its anti-inflammatory properties.
    • Rheumatoid Arthritis: Reduces inflammation in joints (knees and elbows).
    • Mnemonic: Keanu Reeves banging his knee and elbow represents rheumatoid arthritis.

Side Effects

  • Hepatotoxicity (Liver Damage):
    • Liver enzymes should be monitored.
    • Patients advised to avoid alcohol.
    • Mnemonic: Director pulls the lever (liver), causing bullets to shoot.
  • Bone Marrow Suppression:
    • Leads to anemia, increased infection risk, and higher bleeding risk.
    • Mnemonic: Empty bones falling to the floor.
  • Gastrointestinal Disturbances:
    • Nausea, vomiting, diarrhea, loss of appetite, and stomatitis (ulcers in the mouth).
    • Mnemonic: Keanu Reeves feeling nauseous; his face green.

Folic Acid Supplementation

  • Can treat severe GI side effects of methotrexate.
  • Important to consult a provider as it can reverse methotrexate's effects.

Teratogenicity

  • Methotrexate can cause birth defects (teratogenic).
    • Should not be given during pregnancy.
    • Patients should avoid pregnancy for at least three months after discontinuation.
    • Mnemonic: Tarantula symbolizes teratogens.

Key Points

  • Methotrexate is a folate antagonist used for cancer and autoimmune diseases.
  • Side effects include hepatotoxicity, bone marrow suppression, and GI disturbances.
  • Folic acid can alleviate some side effects but requires medical consultation.
  • Methotrexate is teratogenic; not suitable for pregnant women.
