Mechanism of action
Azathioprine works by suppressing the immune system. It does this by inhibiting the production of DNA and RNA in rapidly dividing cells, such as those found in the bone marrow and blood cells. When taken orally, azathioprine is converted into active metabolites within the body. These metabolites interfere with certain enzymes that are essential for DNA synthesis and cell proliferation. By disrupting these processes, azathioprine reduces the activity of immune cells involved in inflammatory responses. The metabolites produced from azathioprine play a crucial role in its immunosuppressive effects. They selectively target rapidly dividing immune cells and inhibit their function. This helps to prevent excessive inflammation and suppresses an overactive immune response commonly seen in autoimmune diseases like rheumatoid arthritis or inflammatory bowel disease.
Medical conditions treated with azathioprine
Azathioprine is a medication commonly used for treating various medical conditions. It is particularly effective in treating autoimmune diseases and preventing transplant rejection. By suppressing the immune system and inhibiting the production of certain white blood cells in bone marrow, azathioprine helps manage conditions such as rheumatoid arthritis, lupus nephritis, and systemic vasculitis. In addition to its role in autoimmune diseases and organ transplantation, azathioprine also serves as an adjunctive therapy for inflammatory bowel disease (IBD). This includes conditions like Crohn’s disease and ulcerative colitis. By reducing inflammation in the intestines and regulating immune responses, azathioprine can help control symptoms of IBD when other treatments have been insufficient or intolerable.
Is it safe with breastfeeding?
It is not recommended to use azathioprine while breastfeeding as the drug is excreted at low levels in breast milk. It is important to consult with your healthcare provider for appropriate alternatives or considerations.
Is it safe to take if I am pregnant or planning on becoming pregnant?
If you are pregnant, planning to become pregnant or suspect you may be pregnant, it is important to discuss the use of azathioprine with your healthcare provider and receive medical advice. They can evaluate the potential risks and benefits to determine the best course of action for your specific situation.
Precautions and warnings for azathioprine
- While you are taking this medicine, you might be asked to have regular blood tests (blood cell counts and liver function tests) to evaluate the medicine’s effectiveness. Regularly monitor blood cell counts when taking azathioprine alongside allopurinol
- Close monitoring of blood pressure and white blood cell counts is important when using azathioprine with ACE inhibitors
- When taking warfarin alongside azathioprine, there is an increased risk of bleeding complications due to enhanced anticoagulant effects. Close monitoring and adjustment of dosage may be necessary to prevent adverse outcomes
- For people with TPMT (thiopurine methyltransferase) deficiency dosage of azathioprine may need to be lowered if tests show that you have TPMT deficiency. TPMT is an enzyme in your body that breaks down azathioprine. When you don’t have enough TPMT, you’re at increased risk of side effects and blood disorders from azathioprine
- Azathioprine may increase your risk of developing certain types of cancer, especially skin cancer and lymphoma. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors
- Azathioprine is very similar to mercaptopurine. Do not use medications containing mercaptopurine while using azathioprine
- It is important to inform a healthcare professional about all the prescription medications including over-the-counter drugs and supplements you are taking to avoid potential drug interactions
