Apo-hydroxychloroquine


However, resistance to the drug also rapidly emerged, with the first cases of Plasmodium falciparum not being cured by administration of chloroquine being reported in the 1950s For example, chloroquine can only be used to prevent Plasmodium falciparum in regions of South America because Plasmodium falciparum is completely resistant to chloroquine in Africa and Asia. Plasmodium vivax. The study objective was to assess the prevalence of hypoglycaemia and P. From 2012 to 2015, more than 75% of malaria cases in Shandong Province were P. In contrast, the proportion and pattern of chloroquine resistance stayed the same, potentially a result of ASAQ use or informal chloroquine use It is widely accepted that several polymorphisms play important roles in chloroquine-resistant P. Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance Abstract.
