Klinisk prövning på Therapeutic Equivalency: Azathioprine

Towards Individualized Drug Dosage - General - DiVA

Excessive methylation via thiopurine methyltransferase (TPMT) frequently causes therapeutic failure. Allopurinol reduces excessive 6-methyl-mercaptopurine (6-MMP) while enhancing 6-thioguanine (6-TGN) levels. The aim of this study was to evaluate clinical, metabolic and endoscopic impact of allopurinol in combination with low-dose thiopurine in IBD. Se hela listan på frontiersin.org Metabolism of thiopurine drugs--azathioprine, 6-mercaptopurine, and 6-thioguanine--has provided a powerful pharmacogenetic model incorporating polymorphism of the enzyme thiopurine methyltransferase (TPMT) and the primary active metabolite, thioguanine nucleotide (TGN). 2-Mercaptopurine | C5H4N4S | CID 3015569 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities Thiopurine therapy has proven its value in maintenance of remission, decreased need for surgery, lowered colorectal cancer risk, less phenotypic disease progression, and synergistic effects when used with infliximab therapy, including increased biologic drug levels and less antibody formation. Catalyzes the S-methylation of thiopurine drugs such as 6-mercaptopurine (also called mercaptopurine, 6-MP or its brand name Purinethol) using S-adenosyl-L-methionine as the methyl donor (PubMed:18484748). TPMT activity modulates the cytotoxic effects of thiopurine prodrugs.

Thiopurine active metabolites persist in the blood for a long time in contrast to MP plasma concentration that rapidly declines after oral administration (MP serum peak is achieved within 2 h, half-life ranges from 20 to 120 min according to patients age and drug formulation): TGN are detected in RBC by the 3rd day of treatment and reach the steady state around the 3rd week; in IBD patients Thiopurine drugs—6-mercaptopurine (6-MP), 6-thioguanine, and azathioprine—are used in the treatment of leukemia, autoimmune disorders, and solid tumors, as well as in organ transplantations. Among these purine and pyrimidine metabolites, 6-MP is the most prescribed drug for … 2001-04-01 Thiopurines, including azathioprine, 6-mercaptopurine, and thioguanine, are medicines used to manage several different conditions and your genes can affect how well the drugs work. CPIC updates guidelines on how to best use these genetic results to support patient care and has published its current interpretations here .

SUMMARY OF PRODUCT CHARACTERISTICS 1. NAME OF

Sixty per cent of patients with IBD receive thiopurines (azathioprine (AZA), mercaptopurine (MP) and to a lesser extent tioguanine) with proven efficacy in maintaining steroid-free remission.1 Although the evidence for the use of thiopurines in UC is not as strong as in patients with CD, it has been demonstrated that in patients with steroid-dependent UC, 53% achieved steroid-free remission on AZA compared with 21% on aminosalicylates.2 Therefore, thiopurines are recommended once a patient *Chevaux JB, Peyrin-Biroulet L, Sparrow MP. Optimizing thiopurine therapy in inflammatory bowel disease.

Phenotype test used to optimize therapy for patients who are taking thiopurine drugs. Thiopurine metabolite concentrations are identified to assess therapeutic and toxic concentrations. If thiopurine therapy has not been initiated, order Thiopurine Methyltransferase, RBC (0092066).
