PRIMARY outcome

Timeframe: serial pharmacokinetic blood samples drawn within one hour prior to dosing (hour 0) and at 0.5, 1, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 24, 36 and 48 hours after dose administration.

Population: Data for 26 of the 27 subjects were used in the statistical analysis for Treatments A and C. The data for one subject, who dropped from the study prior to period III dosing (Treatment B), was included in the comparison of Treatments A versus C. Treatment A, Dose Adjusted to 300 mg was used to evaluate for dose proportionality.

The maximum or peak concentration that the drug reaches in the plasma.

Each subject received one tablet of Quinine Sulphate 300 mg after an overnight fast of at least 10 hours.
Treatment C - Quinine Sulfate 324 mg Caps, Fed Conditions
n=26 Participants
Each subject received one capsule of Quinine Sulfate 324 mg thirty minutes after the initiation of a standardized, high-fat breakfast following an overnight fast.
