The knowledge of this remedy was lost for thousands of years, while the Western world, coping with the seemingly insoluble problem of malaria, relied mainly on strategies such as DDT spraying into the 1950s8.
What is the first drug to treat malaria?
The first pharmaceutical used to treat malaria, quinine, was derived from the tree bark of Cinchona calisaya [5]. Quinine synthesis was first attempted in 1856 by William Henry Perkins, but synthesis was not successful until 1944.

In 1820, two French chemists isolated quinine from the cinchona bark and quinine became a treatment of reference for intermittent fever throughout the world. Quinine remains an important and effective treatment for malaria today, despite sporadic observations of quinine resistance.
How long is malaria treatment?
In general, it takes about two weeks of treatment to be cured of malaria. However, in some individuals, relapses are possible. The time period from initial parasite infection to the appearance of symptoms varies according to the particular species of Plasmodium that infects an individual. For example, P.

Why are antimalarial agents resistant?
Resistance to antimalarial agents arises because of the selection of parasites with genetic changes (mutations or gene amplifications) that confer reduced susceptibility. Gametocytes. The sexual stages of malaria parasites that infect anopheline mosquitoes when taken up during a blood meal. Fixed-dose combination.
What is ACT therapy?
Artemisinin-based combination therapy (ACT) A combination of an artemisinin derivative with a longer-acting antimalarial that has a different mode of action. Asexual cycle. The life cycle of the malaria parasite in the host, from merozoiteinvasion of red blood cells to schizontrupture (merozoite → ring stage→ trophozoite→ schizont → merozoites).
What is malaria pigment?
Malaria pigment (haemozoin) A dark-brown granular material formed by malaria parasites as a by-product of haemoglobin digestion. Pigment is evident in mature trophozoites and schizonts. It may also be phagocytosed by monocytes, macrophages and polymorphonuclear neutrophils.
What is asymptomatic parasitaemia?
Asymptomatic parasitaemia. The presence of asexual parasites in the blood without symptoms of illness. Cerebral malaria. Severe P. falciparummalaria with coma (Glasgow coma scale < 11, Blantyre coma scale < 3); malaria with coma persisting for > 30 min after a seizure.
What is the name of the parasite that is infective to humans?
Severe falciparum malaria. Acute falciparum malaria with signs of severity and/or evidence of vital organ dysfunction. Sporozoite. Motile malaria parasite that is infective to humans, inoculated by a feeding female anopheline mosquito, that invades hepatocytes.
What stage of development is malaria?
The stage of development of malaria parasites growing within host red blood cells from the ring stageto just before nuclear division. Mature trophozoites contain visible malaria pigment. Uncomplicated malaria. Symptomatic malaria parasitaemia with no signs of severity and/or evidence of vital organ dysfunction.
What is the term for a high density of parasites in the blood?
Hyperparasitaemia. A high density of parasites in the blood, which increases the risk of deterioration to severe malaria (although the risk varies in different endemic areas according to the level of transmission) and of subsequent treatment failure.
