atovaquone and proguanil (Malarone)

Atovaquone and proguanil is an anti-malarial medication. Atovaquone blocks mitochondrial electron transfer and thereby the production of energy for use by the parasites. Proguanil is metabolized into its active metabolite, cycloguanil, which blocks dihydrofolate reductase and enzymes required for making pyrimidine which is a chemical needed for production of DNA.
