Summary:

      The primary objective of this study is to compare the bioavailability of two formulations
      (tablets and granules for dispersion) of the antimalarial drug pyronaridine-artesunate [3:1]
      (Pyramax, PA) in healthy adults. The secondary objective is to compare the safety of the two
      PA formulations and liver function test changes following the first and second
      administrations.
