OBJECTIVE
The thiopurine medications are standard inflammatory bowel disease treatments. Therapeutic failure is observed, however, often because of variable drug metabolism. Allopurinol can enhance the potency of thiopurine treatment. Our objective is to review the relevant literature, and our own experience, to determine if allopurinol enhancement of thiopurine treatment is a reasonable therapeutic strategy.
CONCLUSIONS
Published reports of, and our own experience using, allopurinol-thiopurine combination therapy indicate that the addition of allopurinol will enhance thiopurine treatment in up to 60% of patients. There are risks to this approach, but with appropriate monitoring, these risks should approximate those observed with thiopurine therapy alone.
CONCLUSIONS
Combination therapy with allopurinol and a thiopurine is a reasonable alternative for inflammatory bowel disease patients not responding to thiopurine monotherapy. Physicians experienced in thiopurine treatment, who have familiarity with thiopurine metabolism, and are willing to engage in appropriate therapeutic monitoring, should consider this strategy.
