On the morning of Day 1, subjects received a single dose of colchicine 0.6 mg after an overnight fast, followed by a 14 day washout period. On the mornings of Days 15-27, subjects received a daily dose of atorvastatin 40 mg after an overnight fast. On the morning of Day 28, subjects received a co-administered single oral dose of colchicine 0.6 mg and atorvastatin 40 mg following an overnight fast.

PRIMARY outcome

Timeframe: serial pharmacokinetic blood samples drawn prior to dosing on Days 1 and 28 and then 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12 and 24 hours after dose administration.

Population: 24 subjects were enrolled in this study. One subject withdrew from the study prior to Period II check in due to a schedule conflict.

Population: 24 subjects were enrolled in this study. One subject withdrew prior to Period II check-in. The pharmacokinetic parameter, AUC(0-∞), could not be determined for 1 subject in the Colchicine Alone group and for 4 subjects in the Colchicine with Atorvastatin group.

The area under the plasma concentration versus time curve from time 0 to infinity. \[AUC(0-∞)\] was calculated as the sum of AUC(0-t) plus the ratio of the last measurable plasma concentration to the elimination rate constant for colchicine.
