Interacting drug | Toxicity | Interaction Type | Mechanism | Reference |
---|---|---|---|---|
Allopurinol (315-30-0) | Anaemia | Synergistic | Azathioprine is firstly metabolised in the liver to mercaptopurine and then enzymatically oxidised in the liver and intestinal wall by xanthine oxidase to an inactive compound (6-thiouric acid), which is excreted. Allopurinol inhibits first-pass metabolism by xanthine oxidase | Allopurinol-azathioprine interaction |
Allopurinol (315-30-0) | Leucocytopenia | Synergistic | Azathioprine is firstly metabolised in the liver to mercaptopurine and then enzymatically oxidised in the liver and intestinal wall by xanthine oxidase to an inactive compound (6-thiouric acid), which is excreted. Allopurinol inhibits first-pass metabolism by xanthine oxidase | Allopurinol-azathioprine interaction |
Allopurinol (315-30-0) | Pancytopenia | Synergistic | Azathioprine is firstly metabolised in the liver to mercaptopurine and then enzymatically oxidised in the liver and intestinal wall by xanthine oxidase to an inactive compound (6-thiouric acid), which is excreted. Allopurinol inhibits first-pass metabolism by xanthine oxidase | Allopurinol-azathioprine interaction |
Allopurinol (315-30-0) | Thrombocytopenia | Synergistic | Azathioprine is firstly metabolised in the liver to mercaptopurine and then enzymatically oxidised in the liver and intestinal wall by xanthine oxidase to an inactive compound (6-thiouric acid), which is excreted. Allopurinol inhibits first-pass metabolism by xanthine oxidase | Allopurinol-azathioprine interaction |
Mesalazine (89-57-6) | Pancytopenia | Synergistic | The metabolism of azathioprine and mercaptopurine depends on S-methylation by thiopurine methyltransferase (TPMT) and oxidation by xanthine oxidase. An in vitro study using recombinant TPMT found that both sulfasalazine and its metabolites inhibit the activity of TPMT. | Leucopenia resulting from a drug interaction between azathioprine or 6-mercaptopurine and mesalamine, sulphasalazine, or balsalazide |
Trimethoprim (738-70-5) | Haematotoxicity | Additive | Not understood | Neutropenia and thrombocytopenia in renal allograft recipients treated with trimethoprim-sulfamethoxazole |
Captopril (62571-86-2) | Anaemia | Antagonistic | Due to suppression of erythropoietin by the Captopril | Mechanism of angiotensin converting enzyme inhibitor-related anemia in renal transplant recipients |
