Tioguanine

Thioguanine is a cytostatic – a drug that inhibits cell growth and cell division. It also suppresses the function of the immune system to reduce the occurrence of inflammation (immunosuppressant). Thioguanine forms part of the thiopurine class of drugs. It is prescribed to treat certain forms of blood cancer, such as leukaemia. It is also used to treat chronic bowel diseases, such as ulcerative colitis and Crohn’s disease.

Thioguanine and the benefit of DNA analysis

The rate at which thioguanine is processed within your body varies from one individual to another. This means that the efficacy and side effects of thioguanine can be predicted to some extent on the basis of your genes. Preventive DNA analysis can therefore be an important tool in optimising your medication.
