A Drug-Food Interaction Study Between Colchicine and Grapefruit Juice

Completed · Phase 1

Conditions studied: Pharmacokinetics

In brief

Grapefruit juice is an inhibitor of the cytochrome P450 (CYP) 3A4 enzyme system, one of the enzyme systems responsible for the metabolism of colchicine. This study will evaluate the effect of multiple daily consumptions of grapefruit 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.
