Colchicine (Fasted),Colchicine (Fed),Colchicine/Probenecid
All subjects received each of the three study treatments in a randomly assigned sequence of dosing periods. On the morning of Days 1, 15, and 29, each subject received one of the following three treatments: 1) one tablet of colchicine 0.6 mg after an overnight fast of at least 13.5 hours, 2) one tablet of colchicine 0.6 mg after a high-fat breakfast, or 3) one tablet of colchicine 0.5 mg/ probenecid 500 mg following an overnight fast of at least 13.5 hours.

Population: Colchicine(fasted)-could not be determined for Subject 25. Colchicine(high-fat meal)-could not be determined for Subjects 22,25, and 28. Colchicine/Probenecid(fasted)-could not be determined for Subject 25.

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 colchicine plasma concentration to the elimination rate constant.
