Chlorproguanil is a biguanide. Chlorproguanil is active against P. falciparum and P. malariae. Chlorproguanil acts by inhibition of dihydrofolate reductase after cytochrome P450-catalysed cyclization. Chlorproguanil combined with dapsone was developing for the treatment of falciparum malaria. The anti-malarial combination chloroproguanil and dapsone has been withdrawn following demonstration of post-treatment haemolytic anaemia in glucose-6-phosphate dehydrogenase (G6PD) deficient patients in a phase III clinical trial.
