What drug is sold under the name Imuran?
The medication you know under the name Imuran is nothing else than the medical substance called Azathioprine first discovered in 1959. The name Imuran is a commercial name which is owned by a certain pharmaceutical company yet the same medication can be produced by other companies too as the formula was developed a long ago and is no longer protected by the copyright.
The active substance of the preparation is a powerful immunosuppressive preparation of cytotoxic and cytostatic action that is utilized in after an organ transplant to avoid organ rejection, in rheumatoid arthritis, systemic lupus erythematosus, and other conditions of auto-immune nature in which the organism’s immunity renders an inadequate response to its own organs and components.
If your doctor prescribes you to buy Imuran, you can purchase the medication cheaper if you look for Azathioprine or Generic Imuran. They are the same medicines that are manufactured by other companies.
How does Generic Imuran act?
Azathioprine is a structural analog of the natural substances such as adenine, hypoxanthine, and guanine that make up the nucleic acids. It prevents the biosynthesis of nucleotides and suppresses the proliferation of tissues.
The immune-suppressive action is due to the hypoplasia of lymphoid tissue, a lowering of T-lymphocytes volume, a disruption of the synthesis of immunoglobulins, the occurrence in the blood of the atypical phagocytes, and the oppression of cell-mediated hypersensitivity reactions.
After the oral intake of the pills, their active ingredients quickly and completely absorb. The maximum concentration of them in the blood plasma is achieved within one to two hours. After their first passage through the liver, an active metabolite called mercaptopurine is formed.
The active substance is inactivated in the liver with the formation of 6-thiocyanic acid. Oxidation and methylation of the substance occur also in erythrocytes. The blood levels of the drug do not correlate with the potency of its effect because the drug and its metabolite are promptly disposed from the tissues. The preparation is excreted almost completely with bile and only about one percent is excreted in urine.
When you buy Imuran, you should remember that it is excreted into the breast milk and penetrates the placenta so it must not be used during pregnancy or breastfeeding.
When can your doctor prescribe you drugs based on Azathioprine?
The preparation use can be appointed after a transplant surgery to avoid the new organ rejection by the body but the pills cannot be the only medication for this purpose and the complex combination therapy must be followed.
Other indications for the drug use are rheumatoid arthritis, chronic hepatitis, lupus erythematosus, ulcerative colitis, dermatomyositis, myasthenia gravis, periarteritis nodosa, vulgar pemphigus, autoimmune glomerulonephritis, relapsing alternate multiple sclerosis, idiopathic thrombocytopenic purpura, psoriasis, and other auto-immune conditions.
Although here we list the conditions the drug is indicated to be used for, we strongly advise you not to engage in self-treatment and consult a specialist before you buy Azathioprine even if you are diagnosed with one of the above-listed conditions.

The drug must be cautiously used at a doctor’s discretion in chickenpox, herpes zoster, insufficiency of xanthine oxidase, radiation and cytotoxic therapy.
Does Generic Azathioprine interact with other medications?
Since the medication has an immune suppressive effect, it can potentially negatively interact with live vaccines provoking the development of viruses contained in the vaccine. Therefore, it is not recommended to vaccinate people who are administered Azathioprine. As for the inactivated vaccines, their effect can be lowered by the drug use, i.e. there won’t be any protection from the virus against which the vaccine is made.
The concurrent use of Azathioprine with Ribavirin is strongly not advised as it is dangerous with the development of severe bone marrow suppression.
It is advised to avoid combining the drug use with cytotoxic agents, angiotensin-converting enzyme inhibitors, and medications that suppress the bone marrow such as penicillin as it can cause the development of severe hematological changes.
In the concurrent use of Allopurinol, Oxypurinol or Thiopurinol with Azathioprine, the dose of the latter should be lowered by 25% from the regular ones.
The medication suppresses the anticoagulant activity of warfarin and acenocoumarol. Therefore, in a simultaneous use, the higher doses of the anticoagulants may be needed and the monitoring of coagulant probes done frequently.
Before you order Imuran, make sure to tell your doctor about all medicines that you use or plan to use so he or she would decide on the doses and safety of their combination with this immunosuppressive drug.

However, children with excessive body mass can require the use of increased doses of the drug.

The use of the medication in elderly patients
There is limited data on the use of the medication in elderly patients. However, it is considered that the likelihood and severity of the side effects that can potentially develop in them is the same as in adults but considering age changes in the body during the therapy it is important to monitor the liver and kidney function and lower the dose in case of the development of liver or kidney insufficiency.
Therapy of people with liver or kidney insufficiency
The use of the drug in people with liver or kidney insufficiency is possible but in the lowest recommended doses.
Use of the drug in people with thiopurine methyltransferase (TPMT) deficiency
People with complete or partial hereditary TPMT deficiency have a higher risk of severe toxicity of the drug in the use of the standard doses. Therefore, they require the use of the lower doses and constant monitoring of a doctor.
People with heterozygous TPMT deficiency generally well tolerate the regular doses yet some of them may require the use of the lower doses.
Possible side effects of the drug
The use of the drug as a part of combination immunosuppressive therapy after an organ transplant can cause the development of viral, bacterial, or fungal infections. Besides, it may contribute to the oppression of bone marrow function, leukopenia, thrombocytopenia, and anemia. Therefore, during the therapy doctors should monitor the blood composition.
Other possible adverse reactions that you can encounter while using Imuran are nausea, lack of appetite, vomiting, diarrhea, abdominal pain, impaired liver function, cholestatic hepatitis, erosive and ulcerative lesions of the mouth and lips, pancreatitis, ulceration of the stomach and duodenum, intestinal bleeding, necrosis and intestinal perforation, skin rash, and fever; in long-term use - toxic hepatitis. On top of that, there is a chance of the occurrence of benign or malignant neoplasms (malignant develop very rarely).
Overdose dangers and symptoms
The acute overdose of the medication can cause nausea, diarrhea, vomiting, and mild liver function impairment which go away without any measures.
The regular overdosing that can occur as a result of wrongfully chosen daily dose can contribute to the development of unmotivated infections, ulcers in the throat, bruises, and bleeding. These are the results of bone marrow suppression which develops in 9-14 days after the start of the intake of the high dose.
Since there is no specific antidote that can minimize the negative effect of Generic Imuran, it is important to control the blood picture and conduct necessary supporting measures. The intake of activated carbon is reasonable if it is made not later than sixty minutes after the increased dose intake.
