Brief summary: The purpose of this study is to evaluate and compare the relative bioavailability of a single dose of Colcrys™ (colchicine) 0.6 mg when administered to a group of young , healthy subjects 18-30 years of age compared to a group of older, generally healthy subjects 60 years of age or older following an overnight fast.

Detailed description: The purpose of this study is to evaluate and compare the relative bioavailability of a single dose of Colcrys™ (colchicine) 0.6 mg when administered to a group of young, healthy subjects 18-30 years of age compared to a group of older, generally healthy subjects 60 years of age or older following an overnight fast. On study Day 1 following an overnight fast, twenty healthy, non-smoking, non-obese male and female subjects between the ages of 18 and 30 and twenty generally healthy, non-smoking, non-obese male and female subjects over 60 years of age will be administered one single dose of Colcrys™ (1 x 0.6 mg tablet). Fasting will continue for 4 hours after the dose. Blood samples will be drawn from all participants before dosing and for 24 hours post-dose on a confined basis at times sufficient to adequately define the pharmacokinetics of Colcrys. Blood sampling will continue on a non-confined basis at 36, 48, 60 and 72 hours post-dose. Subjects will be monitored throughout participation in the study for adverse reactions to the study drug and/or procedures. Vitals signs (temperature, respiratory rate, pulse rate and blood pressure) will be measured in the sitting position prior to dosing. Seated blood pressure and pulse will be measured at approximately 1, 3, 6 and 12 hours after dosing and prior to release from the facility. All adverse events whether elicited by query, spontaneously reported, or observed by clinic staff will be evaluated by the Investigator and reported in the subject's case report form.

Eligibility criteria: Inclusion Criteria:

* Healthy adults 18-30 years of age or generally healthy adults over 60 years of age (elderly subjects with minor renal impairment may be allowed to participate at the discretion of the investigator), non-smoking and non-pregnant (post-menopausal, surgically sterile or using effective contraceptive measures) with a body mass index (BMI) of 18-30 kg/m2.

Exclusion Criteria:

* Recent participation (within 30 days) in other research studies
* Recent significant blood donation or plasma donation
* Pregnant or lactating
* Test positive at screening for human immunodeficiency virus (HIV), hepatitis B surface antigen (HbsAg), or hepatitis C virus (HCV)
* History of treatment for drug or alcohol addiction within the previous 12 months or excessive alcohol consumption during the past 12 months
* Significant history of chronic infectious disease, system disorders, organ dysfunction, especially cardiovascular disorders (angina, heart failure, irregular heartbeats, heart attack, hypertension, hypotension) stroke, renal or hepatic disorder, diabetes or bleeding disorders, gastrointestinal disease or psychiatric disorders.
* Presence of a medical condition requiring regular treatment with prescription drugs
* Subjects who have used any drugs or substances known to inhibit or induce drug-metabolizing enzymes within 30 days prior to the first dose and throughout the study
* Drug allergies or sensitivity to colchicine
* Positive test results for drugs of abuse at screening

Primary outcomes:
