The life cycle of malaria parasites. Sporozoites are introduced by a mosquito bite. They migrate to the liver, where they multiply into thousands of merozoites. The merozoites infect red blood cells and replicate, infecting more and more red blood cells. Some parasites form gametocytes, which are taken up by a mosquito, continuing the life cycle.

Antimalarial medications or simply antimalarials are a type of antiparasitic chemical agent, often naturally derived, that can be used to treat or to prevent malaria, in the latter case, most often aiming at two susceptible target groups, young children and pregnant women.

- Antimalarial medication

Mefloquine, sold under the brand name Lariam among others, is a medication used to prevent or treat malaria.

- Mefloquine

This parasite is the most frequent and widely distributed cause of recurring malaria.

- Plasmodium vivax

Most deaths are caused by P. falciparum, whereas P. vivax, P. ovale, and P. malariae generally cause a milder form of malaria.

- Malaria

Quinine is an alkaloid that acts as a blood schizonticidal and weak gametocide against Plasmodium vivax and Plasmodium malariae.

- Antimalarial medication

It is especially useful in areas where there is known to be a high level of resistance to chloroquine, mefloquine, and sulfa drug combinations with pyrimethamine.

- Antimalarial medication

Mefloquine is used as a treatment for chloroquine-sensitive or resistant Plasmodium falciparum malaria, and is deemed a reasonable alternative for uncomplicated chloroquine-resistant Plasmodium vivax malaria.

- Mefloquine

It is not recommended for severe malaria infections, particularly infections from P. falciparum, which should be treated with intravenous antimalarials.

- Mefloquine

The recommended treatment for malaria is a combination of antimalarial medications that includes artemisinin.

- Malaria

The second medication may be either mefloquine, lumefantrine, or sulfadoxine/pyrimethamine.

- Malaria

Where an artemisinin-based combination therapy has been adopted as the first-line treatment for P. falciparum malaria, it may also be used for P. vivax malaria in combination with primaquine for radical cure.

- Plasmodium vivax

Mefloquine is a good alternative and in some countries is more readily available.

- Plasmodium vivax

Chloroquine is a medication primarily used to prevent and treat malaria in areas where malaria remains sensitive to its effects.

]]Chloroquine has been used in the treatment and prevention of malaria from Plasmodium vivax, ''[[Plasmodium ovale|P.

In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.
