Abstract Objective: A single cross-over, comparative pharmacokinetic study of oral and rectal formulations of 200 mg artesunic acid in 12 healthy Malaysian volunteers is reported. Methods: Plasma concentrations of artesunic acid and dihydroartemisinin were determined simultaneously by HPLC with electrochemical detection. The test drug was well tolerated and no undesirable adverse effects were observed. Results: Comparison of pharmacokinetic parameters of artesunic acid after oral and rectal administration showed statistically significant differences in t max and AUC, with no changes for C max and t 1/2. As for dihydroartemisinin, differences were observed for t max and C max but not for AUC. Conclusion: There appear to be pharmacokinetic differences between oral and rectal modes of administration. The significance of these findings should be explored in malaria patients before appropriate therapeutic regimens are devised.
