Malaria is caused by a protozoal parasite called Plasmodium, which is carried by
mosquitoes. During a bite from an infected mosquito, the parasite passes into the body.
Once inside, it lives and reproduces, resulting in the disease known as malaria.
The malaria parasites have various stages in their lifecycle within the body. After entering
the bloodstream during a bite from an infected mosquito, they are carried to the liver where
they reproduce. They are then released back into the bloodstream where they infect red
In the red blood cells, the malaria parasites digest haemoglobin, the red protein within red
blood cells that is responsible for carrying oxygen. When this happens, the haemoglobin is
divided into two parts; haem and globin. Haem is toxic to the malaria parasites. They
protect themselves from it by producing a substance that converts the toxic haem into a
compound called haemozoin, which is not toxic to the parasites.
Artemether and lumefantrine both work by interfering with the ability of the malaria
parasites to convert haem into haemozoin. This causes levels of the toxic haem to rise,
which kills the blood stages of the malaria parasites and stops the infection from
