Design outcomes

Primary

MeasureTime frame
Evaluation of the bioavailability in fastening conditions of a single dose administration of three primaquine formulations. Bioavailability will be accessed by the comparison of the pharmacokinetic parameters (AUC0-t, AUC0-inf, Ke, T½, Cmax, Tmax). The acceptance criteria are the estimated ratio of the geometric means of Cmax, AUC0-t of test and reference drugs and their 90% CI within the interval of 80-125%, ;number of adverse events
