Mechanism Of Action and Pharmacodynamic Effects
Cycloguanil, the active metabolite of proguanil, is an inhibitor of Plasmodium dihydrofolate reductase (DHFR). Proguanil has a different mechanism of action when used in combination with atovaquone, with the prodrug having synergistic activity, leading to enhanced collapse of the mitochondrial membrane potential [2].
