other parameters in model implementation

Artenimol (dihydroartemisinin) and piperaquine is a fixed-dose combination antimalarial drug indicated for the treatment of uncomplicated Plasmodium falciparum malaria. Artenimol is a semi-synthetic derivative of artemisinin and acts rapidly against malaria parasites, while piperaquine, a 4-aminoquinoline compound, provides a longer-acting effect, together lowering the risk of recrudescence. It is approved and recommended for use in many endemic regions and is included in the WHO guidelines for malaria therapy.

Pharmacokinetics

Population pharmacokinetics of piperaquine and artenimol in adults and children with uncomplicated P. falciparum malaria (including both sexes), using data from Asian and African populations. Parameters reflect standard oral dosing (3 daily doses at 0, 24, 48 h).
