Transfer the patient to an appropriate full course oral regimen after at least 24 hours of parenteral therapy and once oral medication is tolerated. Dosage recommendations may vary between countries. Refer to local treatment guidelines. Child: Same as adult dose.

Strong UGT inhibitors (e.g. axitinib, imatinib, diclofenac, vandetanib) may increase the plasma concentration of dihydroartemisinin (DHA), the active metabolite of artesunate. Nevirapine, ritonavir, or strong UGT inducers (e.g. carbamazepine, phenytoin, rifampicin) may decrease the plasma concentration of DHA, resulting in reduced or loss of efficacy.
Tác dụng
Description: Mechanism of Action: Artesunate is a semisynthetic artemisinin derivative and a prodrug that is metabolised to the active metabolite, DHA. Both artesunate and DHA contain an endoperoxide bridge that is activated by haeme iron ring binding, leading to oxidative stress, protein and nucleic acid synthesis inhibition, ultrastructural changes and reduced parasite growth and survival. They are active against the blood-stage asexual parasites and gametocytes of Plasmodium species, including chloroquine-resistant strains but inactive against the hypnozoite liver stage forms of Plasmodium vivax and Plasmodium ovale. Pharmacokinetics: Absorption: Time to peak plasma concentration: <1 hour (artesunate); within 15 minutes (DHA). Distribution: Enters breast milk (DHA). Volume of distribution: 68.5 L (artesunate); 59.7 L (DHA). Plasma protein-binding: Approx 93%. Metabolism: Rapidly hydrolysed by blood esterases into DHA, which undergoes glucuronidation. Excretion: Via urine. Elimination half-life: 0.3 hours (artesunate); 1.3 hours (DHA).
