Action Mechanism

Hydroxychloroquine increases pH within cells and alters certain cellular processes. The exact mechanism is unknown but it is presumed that the drug interferes with antigen processing in the cells. The drug diminishes the formation of some protein complexes that are required to stimulate immune cells. Some studies have found that hydroxychloroquine has strong antiviral effects by preventing the viruses to enter the cells.
