Previously referred to as “Resochin”, Chloroquine was first discovered in 1924 at Bayer laboratories. Its first use was initially ignored as it was found to be toxic to people. Chloroquine and ciprofloxacin for typhoid prophylaxis Malaria pills chloroquine Chloroquine disposal For the last decade chloroquine-resistant Plasmodium falciparum CRPF has spread explosively in sub-Saharan Africa. In some areas of the continent, CRPF is so intense that chloroquine can hardly be said to have any efficacy. Chloroquine, used at recorded levels 190 tons hundreds of millions of treatment courses in Africa alone each year, has been a tremendous force driving the widespread replacement of chloroquine-sensitive by chloroquine-resistant P. falciparum. For example, chloroquine-resistant malaria is widespread in sub-Saharan Africa, including Nigeria, and resistance to sulfadoxine-pyrimethamine also occurs in this region. These trials showed that chloroquine eliminated malaria and was appropriate to be used as an antimalarial drug. Thus, it was not until World War II that the government of the United States sponsored the clinical trials of chloroquine as an antimalarial drug.
