Measure
Rosiglitazone Alone, Quinine Alone, Rosiglitazone With Quinine
On the morning of Day 1, subjects received a single dose of rosiglitazone (1 x 4 mg tablet) after an overnight fast of at least 10 hours, followed by a 2 day washout period. On Days 4-7, subjects received a dose of quinine sulfate (2 x 324 mg capsules) every 8 hours beginning at 7:15 am on Day 4 and continuing through the 11:15 p.m. dose on Day 7. On the morning of Day 7, subjects received a single dose of rosiglitazone (1 x 4 mg tablet) along with the morning dose of quinine sulfate ( 2 x 324 mg capsules).

Population: Twenty Three (23) subjects were enrolled in this study. Five (5) subjects withdrew from the study. Pharmacokinetic analyses are based upon data obtained from the eighteen (18) subjects that completed the study.

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 rosiglitazone.
