Artesunate Tablet (Artesunate)
Artesunate Tablet is a water-soluble hemisuccinate derivative of artemisinin. It is unstable in neutral solution and the injectable formulation must be prepared immediately before use in 5% (w/v) sodium bicarbonate solution to produce the salt sodium. After parenteral administration, it is rapidly hydrolysed to the active metabolite dihydroartemisinin. The oral formulation is probably hydrolysed completely before entering the systemic circulation. Artesunate has been reported to clear fever in patients with severe falciparum malaria 16-25 hours after parenteral administration.
