Indications

It is used to treat various types of cancer, including gestational choriocarcinoma, chorioadenoma destruens, and hydatidiform mole. It is also used for acute lymphoblastic leukemia, advanced non-Hodgkin’s lymphoma, breast cancer, head and neck cancer, and lung cancer, especially squamous and small cell types. It helps in the management of severe rheumatoid arthritis and juvenile rheumatoid arthritis when other treatments don’t work. Additionally, it is used for severe psoriasis that doesn’t respond to other treatments.

Pharmacology

It works by blocking an enzyme that helps the body make DNA, which affects cell growth. It is especially effective against rapidly growing cells, such as cancer cells and skin cells in psoriasis. Since cancer cells divide more quickly than normal cells, it helps control cancer growth without harming most normal tissues.
