What is Methotrexate? 🔬📚

Methotrexate is a medication that belongs to a class of drugs called antimetabolites. It works by interfering with the growth of certain cells in your body, particularly those that multiply quickly.

Key Uses:

Treating autoimmune diseases such as rheumatoid arthritis and psoriasis
Managing certain types of cancer, including leukemia, lymphoma, and breast cancer
Reducing inflammation and controlling immune system overactivity

Fun Fact: Methotrexate was originally developed as a chemotherapy drug but now plays a major role in autoimmune therapy due to its immune-modulating properties. 🔥

Methotrexate Generic Name Explained

The generic name of a medication is its universally recognized scientific name, unlike brand names, which vary. For methotrexate:

Generic Name: Methotrexate
Common Brand Names: Trexall, Rheumatrex, Otrexup, Rasuvo

Why It Matters: Knowing the generic name ensures you are taking the correct medicine regardless of the brand, which is especially useful for international travel or cost comparisons.

How Methotrexate Works in the Body ✨

Methotrexate targets rapidly dividing cells by inhibiting an enzyme called dihydrofolate reductase (DHFR). This leads to:

Slower growth of cancer cells
Reduced immune system activity in autoimmune diseases
Decreased inflammation

Think of methotrexate as a traffic controller 🚦 — it slows down overactive cell traffic without completely stopping healthy functions.
