Design outcomes

Primary

MeasureTime frame
dosage of colchicine after stable dosage of colchicine at least 3 month in the screening date and plasma concentration before and after 2 hour in the includsion date Plasma concentration,recommendation of colchicine dosage in gouty patients who had renal impairment after stable dosage of colchicine at least 3 month in the screening date and plasma concentration before and after 2 hour in the includsion date population pharmacokinetics model,factor associated for colchicine level after stable dosage of colchicine at least 3 month in the screening date and plasma concentration before and after 2 hour in the includsion date population pharmacokinetic model

Secondary

MeasureTime frame
pattern of colchicine dosage in patients who had renal impairment after stable dosage of colchicine at least 3 month in the screening date percent ratio,activate PBMC in cochicine multiple level in WBC after stable dosage of colchicine at least 3 month in the screening date and plasma concentration before and after 2 hour in the includsion date stimulate by cystral and inflammasome response
