Drug-Food Interaction Study of Seville Orange Juice and Colchicine

Summary

Seville orange juice is an inhibitor of the intestinal cytochrome P450 (CYP) 3A4 enzyme, one of the enzymes responsible for the metabolism of colchicine. This study will evaluate the effect of multiple daily consumptions of Seville orange juice on the pharmacokinetic profile of a single 0.6 mg dose of colchicine. A secondary objective is to evaluate the safety and tolerability of this regimen in healthy volunteers. All study subjects will be monitored for adverse events throughout the study period.
