Mechanism & Pharmacology

Understanding the mechanism of action for Methotrexate assists in comprehending its therapeutic applications. Methotrexate functions primarily as an antimetabolite and folic acid analogue. It plays a critical role in cancer treatment as well as the management of immunological diseases.

Simplified explanation (patient-friendly)

Methotrexate works by:

• Inhibiting cell division
• Activating apoptosis (programmed cell death) in rapidly dividing cells

These actions make it vital for managing conditions such as rheumatoid arthritis and certain cancers.

Clinical terms (Health Canada approved monograph references)

Methotrexate is classified under ATC code L01BA01, designating it as an antitumor and immunomodulating agent. It inhibits dihydrofolate reductase (DHFR), disrupting the synthesis of nucleotides crucial for DNA replication.

This understanding aids healthcare providers in utilizing Methotrexate effectively for various treatment protocols.
