How Does Malarone Work?

Malarone belongs to the antimalarial class of medications. Malaria is a blood infection caused by tiny parasites called Plasmodium. Plasmodium are usually introduced into the bloodstream by the bite of an infected mosquito. Once in the bloodstream, these parasites start to reproduce.
Malarone prevents Plasmodium parasites from copying nucleic acid, an essential step in their reproduction. The two components of Malarone do this in slightly different ways, allowing them to work well in combination to prevent Plasmodium parasites from reproducing in the bloodstream.
