How does artesunate compare to quinine for severe malaria?

Artesunate works faster at killing parasites than quinine. Clinical studies show it reduces mortality by roughly 35 percent compared with quinine in both adults and children. It also lowers the risk of hypoglycemia, a serious side effect of quinine.

What makes artesunate better than quinine in practice?

Artesunate can be given intravenously or intramuscularly. It reaches peak concentrations quickly and does not require cardiac monitoring like quinine. Most patients show clinical improvement within 24 hours.

Can artesunate replace quinine entirely?

In regions where resistance to artemisinin derivatives has not yet emerged, artesunate has become the recommended first-line treatment for severe falciparum malaria. WHO guidelines list it as the preferred option over quinine.

How does artesunate perform in uncomplicated malaria?

For uncomplicated cases, oral artesunate is rarely used alone. It appears in fixed-dose combination therapies such as artemether-lumefantrine or artesunate-amodiaquine. These pairs reach cure rates above 95 percent when patient adherence is high.
