    Proguanil is a biguanide derivative which is active against several protozoal species and is used in combination with atovaquone and chloroquine for the prevention and therapy of malaria. Proguanil has not been evaluated extensively as a single agent, but the combinations of proguanil with atovaquone or chloroquine have been used to treat malaria and have been linked to serum enzyme elevations. Infections should receive chloroquine prophylaxis 300 mg base po once a week during pregnancy. After delivery, patients with normal G6PD activity should be treated with primaquine or tafenoquine or continue with chloroquine prophylaxis for a total of 1 year. Primaquine can be used during breastfeeding if the infant is found Adult strength tablets 250 mg atovaquone; 100 mg proguanil per tablet PO once daily for 3 consecutive days. Guidelines recommend for chloroquine-resistant infections and for infections of unknown resistance; may also use for chloroquine-sensitive infections if necessary. For P. vivax infections, add primaquine phosphate.

    Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted. Malarone ® atovaquone-proguanil is an effective drug for the treatment and prophylaxis of multidrug-resistant falciparum malaria. However, first cases of resistance have been reported, which are associated with mutations at codon 268 of the parasite's cytochrome b gene. This deficiency explains the reduced ability of chloroquine-resistant parasites to concentrate chloroquine, and it suggests that chloroquine resistance is due to a decrease in the number, affinity, or accessibility of chloroquine receptor sites on a constituent of the malaria parasite.
