Therapeutic action
– Antimalarial

Forms and strengths, route of administration
– Powder for injection, in 60 mg-vial, with one 1 ml-ampoule of 5% sodium bicarbonate and one 5 mlampoule of 0.9% sodium chloride, for slow IV injection (3 to 5 minutes) or slow IM injection. NEVER ADMINISTER BY IV INFUSION.
– Dissolve the powder in the entire volume of 5% sodium bicarbonate and shake the vial until the solution becomes clear. Then, add the 0.9% sodium chloride into the vial:
• 5 ml of 0.9% sodium chloride to obtain 6 ml of artesunate solution containing 10 mg/ml, for IV injection
• 2 ml of 0.9% sodium chloride to obtain 3 ml of artesunate solution containing 20 mg/ml, for IM injection
Dosage and duration
– Child under 20 kg: 3 mg/kg/dose
– Child 20 kg and over and adult: 2.4 mg/kg/dose
– One dose on admission (H0) then 12 hours after admission (H12) then 24 hours after admission (H24) then, once daily.
Administer parenterally at least 24 hours (3 doses), then, if the patient can tolerate the oral route, change to a complete 3-day course of an artemisinin-based combination. If not, continue parenteral treatment once daily until the patient can change to oral route (without exceeding 7 days of parenteral treatment).
