Pharmacokinetic variables of gemfibrozil and gemfibrozil 1-O-β-glucuronide in nine healthy volunteers after the last dose of 600 mg of gemfibrozil, which was taken 1, 24, 48, or 96 h before time zero (i.e., administration of repaglinide)
Values are mean ± S.D., with the exception of tmax data, which are given as median and range.

AUC0–9 h, area under the plasma concentration-time curve from time 0 to 9 h after repaglinide administration, i.e., beginning 1, 24, 48, or 96 h after the last gemfibrozil dose.
