Chloroquine (8; Figure 6) is a relatively safe, cheap, and effective medication for the treatment of malaria and amebiasis. Savarino et al. 63  reported its antiviral effects. At a molecular level, it increases late endosomal and lysosomal pH, resulting in impaired liberation of virions from endosomes or lysosomes. The virus is therefore unable to release its genetic material into the cell and replicate. 64 ,  65  Furthermore, they hypothesize that chloroquine might block the production of proinflammatory cytokines (such as IL‐6), thereby blocking the pathway that subsequently leads to ARDS. 63
