   “More on Malaria: Sterling-Winthrop Research Institute reports a new, effective antimalarial. Called hydroxychloroquine, its activity (with experimental animals) is equal to that of chloroquine, but it is much safer in large doses. Hydroxychloroquine can be taken orally or by injection and is retained in the blood for a longer period of time than chloroquine.”

   “Seventy-five patients suffering from P. falciparum malaria were treated at Gressier, Haiti, with a single oral dose of hydroxychloroquine, which has the chemical structure 7-chloro-4 (4'-(N-ethyl-N-B-hydroxyethylamino)-1-methylbutylamino)-quinoline diphosphate.”
