Imuran (Azathioprine) - Summary

 
 



WARNING

Chronic immunosuppression with this purine antimetabolite increases risk of neoplasia in humans. Physicians using this drug should be very familiar with this risk as well as with the mutagenic potential to both men and women and with possible hematologic toxicities. See WARNINGS.

 

IMURAN SUMMARY

IMURAN® (azathioprine)
50-mg Scored Tablets
mg (as the sodium salt) for I.V. injection,
equivalent to 100 mg azathioprine sterile lyophilized material.

IMURAN (azathioprine), an immunosuppressive antimetabolite, is available in tablet form for oral administration and 100-mg vials for intravenous injection.

IMURAN is indicated as an adjunct for the prevention of rejection in renal homotransplantation. It is also indicated for the management of active rheumatoid arthritis to reduce signs and symptoms.

Renal Homotransplantation: IMURAN is indicated as an adjunct for the prevention of rejection in renal homotransplantation. Experience with over 16,000 transplants shows a 5-year patient survival of 35% to 55%, but this is dependent on donor, match for HLA antigens, anti-donor or anti-B-cell alloantigen antibody, and other variables. The effect of IMURAN on these variables has not been tested in controlled trials.

Rheumatoid Arthritis: IMURAN is indicated for the treatment of active rheumatoid arthritis (RA) to reduce signs and symptoms. Aspirin, non-steroidal anti-inflammatory drugs and/or low dose glucocorticoids may be continued during treatment with IMURAN. The combined use of IMURAN with disease modifying anti-rheumatic drugs (DMARDs) has not been studied for either added benefit or unexpected adverse effects. The use of IMURAN with these agents cannot be recommended.

NEWS HIGHLIGHTS

Published Studies Related to Imuran (Azathioprine)

Interferon, azathioprine and corticosteroids in multiple sclerosis: 6-year follow-up of the ASA cohort. [2012]
combined with low-dose azathioprine and prednisone in multiple sclerosis... CONCLUSION: The tested combined therapeutic regimen does not improve long-term

A randomized trial of methotrexate versus azathioprine for severe atopic eczema. [2011.08]
BACKGROUND: Patients with severe atopic eczema frequently require systemic treatment to control their disease. Methotrexate and azathioprine are proposed as off-label treatment options, but direct comparisons are lacking. OBJECTIVES: We sought to compare the efficacy and safety of methotrexate versus azathioprine in adults with severe atopic eczema... CONCLUSION: Both treatments achieved clinically relevant improvement and were safe in the short term. Methotrexate and azathioprine are appropriate options for the treatment of severe atopic eczema.

A pragmatic randomized controlled trial of thiopurine methyltransferase genotyping prior to azathioprine treatment: the TARGET study. [2011.06]
AIM: To conduct a pragmatic, randomized controlled trial to assess whether thiopurine methyltransferase (TPMT) genotyping prior to azathioprine reduces adverse drug reactions (ADRs)... CONCLUSION: Our work supports the strong evidence that individuals with TPMT variant homozygosity are at high risk of severe neutropenia, whereas TPMT heterozygotes are not at increased risk of ADRs at standard doses of azathioprine.

Steroids and azathioprine in the treatment of IgA nephropathy. [2011.06]
AIM: IgA nephropathy (IgAN) is a very common glomerulonephritis among young adults, but the best therapeutic approach has not been fully elucidated. This study evaluated the effect of two different treatment regimes in IgAN, steroids alone or in combination with azathioprine... CONCLUSIONS: Both, steroid treatment alone and steroids in combination with azathioprine seem to be effective in reducing the severity of proteinuria and stabilizing renal function in IgAN. Patients who do not respond to steroids may have a better response with the combination of steroids and azathioprine.

Cyclosporine versus azathioprine therapy in high-risk idiopathic membranous nephropathy patients: A 3-year prospective study. [2011.03]
There is no consensus regarding the modality of therapy for idiopathic membranous nephropathy (IMN), especially for patients who did not react to treatment with cytotoxic drugs. This study followed prospectively for 3-year IMN patients who did not react to Ponticelli protocol comparing effects of 2-year course of cyclosporine (CsA) with azathioprine (Aza) treatment both with small doses of prednisolone...

Clinical Trials Related to Imuran (Azathioprine)

Azathioprine Versus Placebo in Pemphigus Vulgaris Treated With Prednisolone [Not yet recruiting]
Description: Pemphigus vulgaris is an autoimmune, chronic and recurrent blistering disease with unknown etiology that affects mucosa and skin of patients with significant morbidity and mortality.

The treatment back-bone is based on prednisolone administration. There are controversies on the opportunity of adding immunosuppressive drugs. For some, they are just corticosteroid sparing drugs. For others, they are disease modifying drugs.

The purpose of this trial is to compare efficacy and safety of azathioprine vs. placebo in new cases of pemphigus vulgaris treated with prednisolone.

Azathioprine & Allopurinol in Inflammatory Bowel Disease Patients [Recruiting]

Imuran Dosing in Crohn's Disease Study [Terminated]
This study will compare two different dosing methods of azathioprine (IMURAN) in participants with Crohn's disease who are currently taking steroids (e. g. prednisone or budesonide)or who have just started steroids. The study can be up to 54 weeks long. All participants enrolled will receive active drug. Participants will take doses either based upon weight or based on the patient's ability to breakdown the drug (monitored by 6-thioguanine nucleotides (6-TGN) metabolite levels in the blood). All patients enrolled in the study will receive active study drug.

Imuran (Azathioprine) Dose-Ranging Study in Crohn's Disease [Recruiting]
The purpose of this study is to identify an optimal weight based dose of azathioprine that is safe and effective in the treatment of subjects with active Crohn’s disease requiring treatment with corticosteroids, and for maintaining remission in those subjects.

Myfortic Versus Azathioprine in Systemic Lupus Erythematosus [Recruiting]
This study is designed to explore the use of myfortic ® in patients with active lupus erythematosus. Similar drugs in this class are increasingly used in organ transplantation and in autoimmune diseases. With the established safety profile of myfortic ® in allo-transplantation and the already existing data of mycophenolate mofetil in autoimmune diseases, this study should help to demonstrate the beneficial effect of myfortic ® on lupus activity. The aim of the study will be to show a decreased disease activity with myfortic ® compared to standard maintenance therapy with azathioprine.

Imuran review by 30 year old female patient

  Rating
Overall rating:  
Effectiveness:   Considerably Effective
Side effects:   Mild Side Effects
  
Treatment Info
Condition / reason:   Lupus
Dosage & duration:   50mg taken once daily for the period of 1.5 years
Other conditions:   asthma
Other drugs taken:   Nuvaring, Prozac, Xanax, Plaquenil, Vicoprofin
  
Reported Results
Benefits:   The treatment reduced the symptoms of SLE that I was suffering from: these were pain and inflammation in my wrists, hands and fingers. It also reduced some puffiness in my face - perhaps b/c I had inflammation in my jaw joint.
Side effects:   I did not notice changes in my hair or skin, but I believe that this drug might increase my fatigue somewhat. I believe this b/c when I went to a higher dose (25 to 50 mg) I needed more rest. I have gained some weight, but am unsure if this is a side-effect of Imuran or of lifestyle changes due to less physical activity. (I suspect it is the latter)
Comments:   1 year at 25 mg .5 year at 50 mg once a day in both cases
