In essence, the parasite cell drowns in its own metabolic products. To avoid destruction by this molecule, the parasite biocrystallizes heme to form hemozoin, a nontoxic molecule. A. Chloroquine resistance in Burkina Faso increased slightly, with predicted purely resistant infection …. There is evidence to support the continued use of amodiaquine to treat uncomplicated malaria, although local drug resistance patterns need to be considered. Similar in structure and activity to chloroquine, amodiaquine is effective against some chloroquine -resistant strains, particularly Plasmodium falciparum, the most deadly malaria parasite Amodiaquine is more effective than chloroquine against P. falciparum chloroquine resistance in the 1950s, resistant strains have appeared throughout East and West Africa, Southeast Asia, and South America.
