Definition: The most important of the alkaloids derived from cinchona; an antimalarial effective against the asexual and erythrocytic forms of the parasite, but having no effect on the exoerythrocytic (tissue) forms. It does not produce a radical cure of malaria produced by Plasmodium vivax, P. malariae, or P. ovale, but is used in the treatment of chloroquine-resistant strains of P. falciparum.
