Mercaptopurine is a medication primarily used to treat certain types of cancer, especially leukemia. It works by interfering with the synthesis of DNA and RNA, which are essential for cell growth and division. Think of it as a targeted weapon against rapidly dividing cancer cells. 🛡️ However, it can also affect normal cells, leading to side effects. It's typically administered as part of a broader chemotherapy regimen. Its effectiveness requires careful monitoring and dosage adjustments.
