Tioguanine

Tioguanine (brand name: Tabloid) is an immunosuppressive drug used to treat certain types of leukemia, autoimmune diseases, and organ transplant rejection. It works by inhibiting the development and activity of certain types of white blood cells that play a role in the immune response. Common side effects of tioguanine include nausea, diarrhea, hair loss, and headaches.

Tioguanine, also known as 6-thioguanine (6-TG), is a medication used to treat several forms of leukemia. Here's a breakdown of its key aspects:

  • Type: Antitumor medication (antineoplastic)
  • Class: Purine analogue antimetabolite
  • Uses: Primarily treats acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), and chronic myeloid leukemia (CML).

How it works: Tioguanine disrupts the growth and division of cancer cells by interfering with their DNA synthesis. Here's a more detailed mechanism:

  • Mechanism of action: It acts as a purine analogue, mimicking natural purine bases (building blocks of DNA). When cancer cells try to incorporate tioguanine into their DNA, it disrupts the normal DNA replication process, hindering cell growth and division.

Important points to remember:

  • Dosage and administration: Tioguanine is typically given orally (by mouth) as a tablet. The dosage and treatment schedule depend on the type of leukemia being treated and the patient's overall health.
  • Side effects: Like many chemotherapy medications, tioguanine can cause side effects, including nausea, vomiting, loss of appetite, mouth sores, decreased white blood cell count (which increases infection risk), and liver problems.
  • Monitoring: Close monitoring by a doctor is crucial during treatment with tioguanine due to potential side effects.

Tioguanine is a powerful medication used under specialist supervision. It's important to note that:

  • Long-term use is not recommended due to potential complications.
  • It's not a first-line treatment for all leukemia cases. Doctors may use it in combination with other chemotherapy drugs.
