Understanding Methotrexate

Methotrexate is a folate analog that interferes with DNA synthesis. It functions primarily by inhibiting dihydrofolate reductase, an enzyme necessary for DNA and RNA synthesis, thereby affecting cell replication.

Primary Medical Uses

Methotrexate has a range of applications in medical treatments due to its capacity to regulate immune responses and impair cell growth.

1. Autoimmune Diseases

• Rheumatoid Arthritis: Methotrexate is commonly prescribed to reduce inflammation and slow disease progression.
• Psoriasis: It helps in managing skin cell overproduction.

• Leukemia: Used as a chemotherapeutic agent to curb the proliferation of cancer cells.
• Lymphomas and Other Cancers: Also found in combination therapy regimens for other cancer types.

Methotrexate impedes cell division. By inhibiting folic acid metabolism, this medication disrupts the proliferation of rapidly dividing cells, which is why it is effective against both cancer cells and certain autoimmune conditions.

Potential Side Effects and Risks

Patients taking methotrexate may experience a range of side effects. These can include:

• Nausea and vomiting
• Fatigue and dizziness
