A mechanism for the synergistic antimalarial action of atovaquone and proguanil.
A combination of atovaquone and proguanil has been found to be quite effective in treating malaria, with little evidence of the emergence of resistance when atovaquone was used as a single agent. We have examined possible mechanisms for the synergy between these two drugs. While proguanil by itself had no effect on electron transport or mitochondrial membrane potential (DeltaPsim), it significa...
متن کاملLengthy antimalarial activity of atovaquone in human plasma following atovaquone-proguanil administration.
Recently, it was reported that sera from healthy volunteers given atovaquone-proguanil (Malarone) inhibited parasite transmission and asexual blood stage development for up to 6 weeks after treatment (1). The lengthy persistence of drug activity was quite unexpected because earlier studies had shown that proguanil and atovaquone had elimination halflives of about 14 to 20 h (2–4, 10, 11) and 2 ...
متن کاملRandomized trial of artesunate-amodiaquine, atovaquone-proguanil, and artesunate-atovaquone-proguanil for the treatment of uncomplicated falciparum malaria in children.
BACKGROUND Artemisinin-based combination therapies (ACTs) are recommended for the treatment of acute uncomplicated falciparum malaria in many malaria-endemic countries. Despite the emergence of artemisinin resistance, few alternative non-ACTs, including atovaquone-proguanil, are currently available. METHODS Plasmodium falciparum-infected Cameroonian children ≤5 years old (n = 338) were random...
متن کاملAtovaquone-proguanil for treating uncomplicated malaria.
BACKGROUND Many conventional treatments for uncomplicated malaria are failing because malaria parasites develop resistance to them. One way to combat this resistance is to treat people with a combination of drugs, such as atovaquone-proguanil. OBJECTIVES To compare atovaquone-proguanil with other antimalarial drugs (alone or in combination) for treating children and adults with uncomplicated ...
متن کاملAtovaquone and proguanil for the treatment of malaria in Brazil.
The purpose of this study was to compare an experimental regimen of atovaquone plus proguanil with the standard regimen of quinine plus tetracycline for the treatment of uncomplicated falciparum malaria. The study was designed as an open, randomized study of men presenting with symptoms of uncomplicated malaria and thick-smear slide confirmation of parasitemia (1000-100,000 ring forms/microL). ...
