Mechlorethamine, also known as nitrogen mustard, is a chemotherapy medication primarily used to treat certain types of cancer, particularly Hodgkin's lymphoma and nonHodgkin's lymphoma. It belongs to a class of drugs known as alkylating agents, which work by interfering with the DNA of cancer cells, preventing them from dividing and growing. Mechlorethamine is often administered in a clinical setting due to its potency and potential side effects.

Uses of Mechlorethamine

Mechlorethamine is approved for several medical uses, including:

• לימפומה של הודג'קין: It is commonly used in combination with other drugs to treat this type of cancer.
• NonHodgkin's Lymphoma: Effective in treating various forms of this cancer.
• Cutaneous TCell Lymphoma: Used for skinrelated lymphomas that do not respond to other treatments.
• סרטן אחר: Occasionally used for other malignancies as determined by a healthcare provider.

איך זה עובד

Mechlorethamine works by damaging the DNA in cancer cells. It does this by adding an alkyl group to the DNA, which leads to crosslinking of the DNA strands. This crosslinking prevents the cancer cells from replicating and ultimately leads to cell death. In simpler terms, it disrupts the cancer cells' ability to grow and multiply, helping to control the spread of the disease.
